Estoy empezando a usar Google Charts API y estoy viendo algunos aspectos curiosos sobre su comportamiento. En primer lugar me di cuenta de que mi gráfico de muestra no se carga cuando me colocó el código de google gráfico dentro de la document. ready de jQuery. Entonces jugé y hice lo siguiente:

Esto funciona como esperaba, pero cuando abro herramientas de desarrollador veo que la solicitud GET para google. com/jsapi aparentemente falló (indicada por la X roja en las herramientas de desarrollo de Chrome). El gráfico ciertamente aparece en la página y funciona como yo esperaría, sin embargo. Por qué funciona esta iteración actual, mientras que la colocación de todo dentro de la document. ready no? Si yo quisiera usar gráficos de Google en un proyecto junto con jQuery esto sería un método viable de hacer tan?

No hay necesidad de poner el código de gráfico dentro de una llamada lista de documentos - de hecho, es más probable que encuentre problemas para hacer eso de lo que eres si lo dejamos por su cuenta:

En otra nota, veo que estás llamando $ ( '# chart'). FadeIn (); Después de dibujar el gráfico. Supongo que esto significa que el gráfico está oculto antes del dibujo, lo que puede causar problemas en algunos navegadores. El curso de acción recomendado es mostrar el div antes de dibujar y ocultarlo de nuevo inmediatamente después de dibujar (de un manejador de eventos "listo"). A continuación, puede llamar al efecto fadeIn:

El gráfico jqPlot más básico toma una serie de datos y traza una línea. No es necesario proporcionar ninguna opción. Los datos se transmiten como un conjunto de series. Una serie puede ser una matriz de valores y o una matriz de pares de datos [x, y]. Si sólo son valores y, los valores x se asignan como 1, 2, 3. Nota, para esta gráfica no necesita ningún complemento.

La siguiente trama utiliza varias opciones para definir el título, añadir etiquetas de eje y muestra cómo usar el complemento canvasAxisLabelRenderer para proporcionar etiquetas de eje giradas.

Hay numerosas opciones de estilo de línea para controlar cómo se muestran las líneas y los marcadores.

Gráficos dinámicos HTML5 y JavaScript

CanvasJS le permite crear gráficos dinámicos que se actualizan en un intervalo dado. Las gráficas dinámicas son útiles para mostrar datos que cambian con el tiempo como el precio de las acciones, la temperatura, etc. Las actualizaciones dinámicas son compatibles con todos los tipos de gráficos, incluyendo línea, área, columna, barra, pastel, etc. Gráficos Las cartas dinámicas también se conocen como cartas en vivo o cartas en tiempo real. Los ejemplos incluyen código fuente para todos los gráficos.

Los gráficos son una gran ayuda visual cuando se presentan datos. No puede crear un panel de administración profesional sin ellos. También son difíciles de configurar. Sin embargo, hay una nueva biblioteca que hace las cosas más fáciles & # 8211; XCharts. Hoy, vamos a usarlo junto con el selector daterange para Twitter Bootstrap. Para construir un gráfico bonito, AJAX-accionado para su uso de la tela que recoge datos de una tabla de MySQL.

El HTML

La estructura HTML de la demo es bastante simple & # 8211; Tenemos que agregar elementos en la página para la inicialización del gráfico y para el selector de fechas. Como estamos incluyendo bootstrap en la página de todos modos, podemos hacer uso de sus habilidades de estilo de formulario y los iconos para que se vea bien.

index. php

Estamos incluyendo una gran cantidad de recursos externos aquí. En la sección head, tenemos los archivos css para xcharts. El datepicker. Bootstrap (incluido desde cdn super rápido de cloudflare), y nuestro archivo style. css.

Antes de la etiqueta body de cierre, tenemos la biblioteca jQuery, d3.js (requerido por xcharts), xcharts. La elegante biblioteca de sugar. js (requerida por el complemento de rango de fechas), el complemento de rango de fechas y nuestro script. js. En los próximos pasos verá cómo todos estos trabajos juntos.

La tabla MySQL

Como mencioné en la introducción, el guión que estamos escribiendo buscará sus datos de una tabla MySQL y los mostrará en el gráfico. Puede encontrar el código SQL que creará la tabla en schema. sql en el archivo zip, disponible para descargar desde los botones de arriba. Esto es lo que parece la tabla:

Tiene sólo tres campos. Al campo de fecha se le asigna un índice único, lo que significa que no puede haber registros duplicados para el mismo día. El campo sales_ord contiene el número de ventas del día. Su base de datos seguramente será diferente, pero siempre y cuando devuelva la respuesta JSON correcta de su script PHP, no habrá ningún problema (más sobre eso en la próxima sección).

Nota . Recuerde introducir los detalles de conexión de MySQL en setup. php. A continuación, tendrá que crear una nueva base de datos MySQL, e import schema. sql de phpMyAdmin o su sistema de gestión de elección.

El código PHP

En nuestro script PHP, seleccionaremos los registros de la tabla que corresponden a la fecha de inicio y fin pasada, montaremos una matriz y la mostraremos como JSON:

ajax. php

Aquí estoy usando una biblioteca favorita mía & # 8211; Idiorm. Lo he usado antes en tutoriales en el sitio (y en muchos proyectos personales). Es sólo un archivo (ubicado en la lib / carpeta) y hace que trabajar con bases de datos sea una pura alegría. Todo lo que estoy haciendo es seleccionar todos los resultados de la base de datos, que tienen un valor de fecha entre el inicio y final timestamps pasó con la solicitud.

La respuesta JSON resultante es similar a esto:

Las propiedades de etiqueta contienen los valores de fecha MySQL para la fila respectiva y los valores & # 8211; El número de ventas para ese día. Depende de nuestro código JavaScript manejar correctamente estos datos y convertirlo en un formato adecuado para su uso con el complemento xCharts.

Pretty Charts con jQuery y AJAX

el JavaScript

Todo nuestro código JS se encuentra en assets / js / script. js. El código es un poco largo, y para que sea más fácil de seguir, se lo presentaré en trozos.

Primero declararemos algunas variables e inicializaremos el complemento selector de rango de fechas. Tenga en cuenta que el intervalo de fechas a las que he vinculado es un fork del complemento original. Decidí ir con esta versión, ya que el original depende de date. js & # 8211; Una biblioteca de fecha / hora muy antigua que entra en conflicto con xCharts. La bifurcación en su lugar utiliza sugar. js, que es una biblioteca de utilidad agradable con poderoso soporte de fecha y hora.

Assets / js / script. js

Como puede ver, estamos haciendo buen uso de sugar. js & # 8217; Fecha y hora para definir el punto inicial y final del rango. Estoy inicializando el script con los resultados de los últimos 7 días, y actualizando el campo de entrada del rango.

Ahora, cree el gráfico:

Primero defino un objeto de configuración para xCharts, con propiedades y funciones de devolución de llamada. En la propiedad dataFormatX, estoy transformando las cadenas aaaa-mm-dd devueltas de la solicitud AJAX, en objetos JavaScript Fecha adecuados, para que el complemento pueda mostrarlos correctamente y hacer sus cálculos.

También estoy pasando un controlador de eventos para los eventos de plugin mouseover / mouseout, y los uso para mostrar una información de herramientas (el plugin no viene con uno fuera de la caja).

Manejo de intervalos de fechas

Por último, aquí está la función JavaScript para cargar datos con AJAX:

XCharts expone el método setData para que pueda reemplazar fácilmente los datos mostrados. El atributo className es importante, ya que esto es lo que utiliza el complemento para identificar su gráfico. Si omite esta propiedad, se producirá todo tipo de errores extraños (confía en mí, lo sé).

¡Con esto nuestros gráficos bonitos están completos!

Estamos hechos!

Puede utilizar este ejemplo para mejorar sus áreas de administración y para visualizar datos estadísticos en una interfaz hermosa.

Presentación de Bootstrap Studio

Una herramienta revolucionaria que los desarrolladores y diseñadores usan para crear interfaces hermosas usando el Bootstrap Framework.

A veces más que la aplicación en sí, me encanta cómo me han presentado a un montón de útiles bibliotecas del lado del servidor / cliente (heck, incluso migró mi blog a Linode gracias a las recomendaciones de este sitio, y no podría estar más feliz) . En este caso no conocía Idiorm, que parece perfecto para las aplicaciones que necesitan un DB, pero no un marco de pila completa. Claro que podría ensamblar varias bibliotecas de compositores para construirlo, pero que podría ser un poco & quot; demasiado.

Gracias, Martin.

Agradecimiento Pero tengo el estilo de la conexión del cambio de la bruja del problema. Conecto bruja

$ Db_host = 'xxxl'; $ Db_user = 'xxx'; $ Db_pass = 'xxx'; $ Db_database = 'xxx'; $ Link = mysql_connect ($ db_host, $ db_user, $ db_pass) o die ( 'error');

Mysql_select_db ($ db_database, $ link); Mysql_query (& quot; SET names UTF8 & quot;);

$ Results = & quot; SELECT suma (sales_order), fecha FROM chart_sales WHERE date & gt; = '& quot;. $ Start. & Quot;' Y date & lt; = '& quot;. $ End. & Quot;' GROUP BY fecha ORDER BY fecha ASC &;

Ahora estoy atascado bruja json_encode :( O podría explicar cómo utilizar Idiorm función pública suma?

Martin Angelov dice:

Deberías escapar de las variables $ start y $ end antes de incluirlas en tu consulta, ya que ahora tu código está abierto a ataques de inyección de SQL. Le aconsejo que utilice pdo o una biblioteca como idiorm que desinfectar sus variables automáticamente.

No estoy seguro de lo que quieres hacer con tu consulta. Desea mostrar una suma de todas las ventas del período? Si desea convertir sólo el código de Idiorm a funciones mysql_, no necesita la parte sum () - sales_order ya tiene la suma de las ventas del día.

Hola, tengo el campo de fecha de la bruja de la base de datos no se asigna un índice único.

id fecha | Sales_order 1 | 2013-01-01 | 10 2 | 2013-01-01 | 23 3 | 2013-01-02 | 67 4 | 2013-01-02 | 67 etc.

Ahora intento sum () 'sales_order' y la fecha GROUP BY. No sé utilizar Idiorm función sum () en este caso, por lo que estoy tratando de convertir el código de Idiorm a mysql_ funciones :) Gracias por su respuesta

OK, Ahora veo mi error. & Quot; .. siempre y cuando devuelva la respuesta JSON correcta de su secuencia de comandos PHP, no habrá ningún problema & quot ;. Tuve un error al crear mysql_ funciones :)

Tengo una solicitud: Puedes darme un ejemplo para escapar de las variables $ start y $ end? Todavía estoy aprendiendo :)

Actualización a jQuery Visualice: Gráficos accesibles con HTML5 desde el diseño con mejora progresiva

Publicado por Maggie el 03/12/2010

Hace un tiempo, creamos una técnica para crear gráficos y gráficos accesibles que usan JavaScript para raspar datos de una tabla HTML y generar visualizaciones de barras, líneas, áreas y gráficos circulares usando el elemento de lienzo HTML5. Esta técnica proporciona una forma sencilla de generar gráficos, pero lo que es más importante, ya que basa el gráfico en los datos que ya están en la página en un elemento de tabla HTML, es accesible a las personas que navegan por la Web con un lector de pantalla u otra tecnología de asistencia o Con navegadores que no soportan completamente JavaScript o lienzo HTML5. Lo empaquetamos como un plugin jQuery descargable llamado Visualize.

Hemos actualizado el complemento Visualize - agregando atributos de ARIA para aclarar el papel del gráfico a los usuarios de lectores de pantalla, por lo que están mejor informados sobre qué elementos contienen datos útiles; Y proporcionar dos variaciones de estilo para demostrar cómo se puede utilizar CSS para personalizar la apariencia de las cartas.

Cómo funciona el complemento Visualize

La visualización de datos accesibles en HTML siempre ha sido difícil de conseguir: las personas usan comúnmente elementos de imagen para gráficos estáticos, que proporcionan sólo la información textual más básica a los usuarios no visuales; O plugins propietarios para gráficos interactivos, que requieren descargas y actualizaciones por parte del usuario y no siempre abordan completamente los problemas de accesibilidad.

El elemento de lienzo HTML5 proporciona un avance importante comparado con los métodos tradicionales: su API de dibujo JavaScript nativa nos permite dibujar de forma dinámica imágenes de mapa de bits en la página, lo que significa que podemos usar Canvas para generar gráficos y gráficos basados en datos que ya están disponibles en HTML.

El complemento Visualize analiza elementos de contenido de clave en una tabla HTML bien estructurada y aprovecha la capacidad de dibujo de lienzo HTML5 nativo para transformarlos en una visualización gráfica o gráfica. Por ejemplo, los valores de datos de la fila de la tabla sirven como barras de gráfico, líneas o cuadrados de pastel; Los encabezados de tablas se convierten en etiquetas de valor y leyenda; Y los valores de título y título proporcionan etiquetas de título dentro de la imagen. Visualize también comprueba automáticamente los valores más altos y más bajos en el gráfico y los utiliza para calcular los valores del eje x para los gráficos de líneas y barras. Por último, el complemento incluye dos estilos CSS diferentes, uno claro y otro oscuro, que puede utilizarse tal como está o puede servir como punto de partida para personalizar la presentación de gráficos y gráficos para que coincida con cualquier estilo de aplicación.

Soporte de ARIA ahora incluido

Aunque este enfoque para crear gráficos y gráficos es inherentemente accesible - los datos de la tabla permanecen en el marcado de página para lectores de pantalla y navegadores que no soportan JavaScript - nos dimos cuenta de que el elemento canvas necesitaba atributos ARIA para identificarlo mejor como una visualización. En la última actualización de Visualize, editamos el complemento para asignar automáticamente dos atributos de ARIA al contenedor de gráficos para identificar más claramente su propósito para los lectores de pantalla:

Role = "image" - le dice a los lectores de pantalla que el gráfico es puramente visual, y por lo tanto se puede omitir

Aria-label = "Gráfico que representa datos de: [valor del título de la tabla]" - identifica específicamente el contenido del gráfico como perteneciente a la tabla asociada

Visualice en acción: una demostración rápida

En el siguiente ejemplo, tenemos una tabla HTML llena de datos de muestra de un número de empleados y sus ventas por departamento de tienda. Hemos generado 4 gráficos de esta tabla, que se muestran a continuación.

NOTA sobre el vínculo "Ver bajo ancho de banda": Esta demostración se ejecuta en nuestro marco EnhanceJS. Que aplica mejoras progresivas basadas en las capacidades del navegador y agrega un enlace "Ver versión de bajo ancho de banda" para permitir a los usuarios cambiar de una vista básica a mejorada, dejando una cookie en el cambio para registrar las preferencias del usuario. Si hace clic en el enlace para ver la versión de bajo ancho de banda de la versión parcial de programa, recuerde que tendrá que volver a hacer clic en ella para ver la versión mejorada de este sitio en vistas futuras. (Puede obtener más información sobre EnhanceJS en el siguiente artículo: Presentación de EnhanceJS: Una forma más inteligente y segura de aplicar mejoras progresivas.)

Cómo usar Visualize

En primer lugar, necesitará crear el marcado de tabla:

Tenga en cuenta que hemos utilizado un elemento de título para resumir los datos de la tabla. Esto será utilizado por Visualize plugin para crear un título en su gráfico. También hemos definido los encabezados de nuestras tablas utilizando los elementos th, permitiendo al script saber qué celdas debe usar como títulos para un conjunto de datos.

Ahora que tenemos nuestra tabla HTML, podemos generar un gráfico. Sólo tiene que adjuntar jQuery y JavaScript de nuestro plugin Visualize y archivos CSS a su página, y llame al método visualize () sobre la tabla, como esto:

¡Eso es! De forma predeterminada, Visualize plugin generará el primer gráfico de barras que se muestra arriba y lo añadirá a su página directamente después de la tabla.

Encontrar un gráfico generado en la página

Una vez que llame al método visualize () en una tabla, el nuevo elemento de gráfico se devolverá al método, lo que le permitirá continuar su cadena jQuery actuando sobre el gráfico en lugar de la tabla. Las gráficas generadas por este complemento están contenidas dentro de un elemento div con una clase de "visualizar", así como una clase del tipo de gráfico, como "visualize-pie". Estas clases hacen que sea fácil encontrar su gráfico después de que se genere, para la presentación adicional y las modificaciones de comportamiento. Otra buena forma de hacerlo es almacenar el gráfico generado en una variable, como esto: var myChart = $ ( 'table'). Visualize () ;. A continuación, puede hacer referencia a myChart más adelante en su secuencia de comandos para realizar cualquier modificación en ella o eliminarla de la página.

Actualización de un gráfico

Cada gráfico generado por el complemento Visualize tiene un evento personalizado que se puede utilizar para actualizarse utilizando sus configuraciones originales, incluida la tabla de la que debe extraer los datos. Esto es útil para páginas dinámicas con gráficos que pueden actualizarse con frecuencia. De hecho, hicimos uso de este evento al crear el ejemplo de tabla editable anterior. Para actualizar un gráfico existente, simplemente desencadene el evento visualizeRefresh en el elemento del gráfico generado, de la siguiente manera:

Agregar el gráfico a otras áreas de la página

Puesto que llamar al método visualize () devuelve el nuevo elemento del gráfico, es fácil añadir inmediatamente el gráfico a otro área de la página usando el método appendTo de jQuery. Sin embargo, una vez que mueve el gráfico a otra área en el DOM, debe activar el método visualizeRefresh en él para que se muestre correctamente en Internet Explorer 6 y 7. El código siguiente muestra anexando el gráfico al final de la página, Y luego activar el método visualizeRefresh en él:

Estilizar las tablas con CSS

Tres archivos CSS acompañan al complemento Visualize que establece el diseño general, los colores de fondo y de texto de las etiquetas de clave, título, cuadrícula y eje:

Visualize. css - establece las propiedades estructurales como la visualización y el posicionamiento que controlan el diseño y la colocación. Esta hoja de estilo se requiere para que los gráficos aparezcan como lo hacen en la demostración.

Visualize-dark. css - contiene propiedades de estilo para el look-and-feel oscuro, como se muestra en la demostración anterior

Visualize-light. css - se puede utilizar en lugar de visualize-dark. css para un aspecto más ligero. (Ver una demostración.)

Configurar Visualize para crear gráficos personalizados

Las siguientes opciones están disponibles para configurar el tipo de gráfico y sus características visuales:

Tipo: cadena. Acepta 'barra', 'área', 'pie', 'línea'. Predeterminado: 'bar'.

Anchura: número. Ancho de la carta. El valor predeterminado es el ancho de la tabla

Altura: número. Altura del gráfico. Por defecto a la altura de la tabla

AppendTitle: boolean. Agregue el título al gráfico. Predeterminado: true.

Título: cadena. Título para el gráfico. El valor predeterminado es el texto del elemento Caption de la tabla.

AppendKey: booleano. Agregue la clave de color al gráfico. Predeterminado: true.

Colores: matriz. Los elementos de matriz son valores hexadecimales, utilizados en orden de apariencia. Predeterminado: [ '# be1e2d', '# 666699', '# 92d5ea', '# ee8310', '# 8d10ee', '# 5a3b16', '# 26a4ed', '# f45a90', '# e9e744']

TextColors: matriz. Los elementos de matriz son valores hexadecimales. Cada elemento corresponde con la matriz de colores. Los elementos nulos / indefinidos volverán al color de texto CSS. Defecto: [].

ParseDirection: cadena. Dirección para analizar los datos de la tabla. Acepta 'x' y 'y'. Valor predeterminado: 'x'.

PieMargin: número. Espacio alrededor del círculo exterior de la carta circular. Valor predeterminado: 20.

PieLabelPos: cadena. Posición de las etiquetas de texto en el gráfico circular. Acepta 'dentro' y 'fuera'. Predeterminado: 'inside'.

LineWeight: número. Peso del trazo para líneas en líneas y gráficos de área. Valor predeterminado: 4.

BarGroupMargin: número. Espacio alrededor de cada grupo de barras en un gráfico de barras. Valor predeterminado: 10.

BarMargin: número. Crea espacio alrededor de las barras en el gráfico de barras (agregado a ambos lados de cada barra). Predeterminado: 1

Para usar las opciones, basta con pasarlas como argumento al método visualize () utilizando la notación literal de objetos, al igual que la mayoría de los complementos jQuery a los que está acostumbrado (por ejemplo: visualize ();).

Soporte del navegador

Hemos probado este complemento en los siguientes navegadores: IE6, IE7, IE8, Firefox 2, Firefox 3.5, Safari 3 y 4, Opera 9.

Para la compatibilidad con Internet Explorer

Este complemento utiliza el elemento de lienzo HTML5, que no se admite en Internet Explorer en este momento. Afortunadamente, Google mantiene una biblioteca que traduce el script de lienzo en VML, llamado excanvas. js, que utilizamos para extender el soporte de Visualize a los navegadores de IE. Hemos incluido una versión ligeramente modificada de excanvas. js con el código zip del complemento Visualize que también es compatible con EnhanceJS. Nuestra biblioteca de pruebas de capacidades.

He añadido una nueva opción porque mis tablas se están cargando con jQuery grid con el formato.

StripFormatting: false // esto elimina la moneda y otro texto del encabezado myTd = "$ -23,333.05"; Cambiado el para cada bucle td a algo como esto

X = stripformatting. $ (This).find ( 'td') eq (i).text (). Match (/ [^ \ d \ .-].texto(); DataGroups. points. push (x * 1);

Comentario de Graham Wallis el 25/03/2010 a las 23:56

Estamos revisando este guión y es bastante impresionante! Sin embargo, encontramos un problema. Usando un gráfico circular, por ejemplo, si está comparando 4 conjuntos de datos y en un ejemplo sólo tiene 1 conjunto que es 100% del pastel, en safari y FF se muestra correctamente. Vemos un pastel completo con 100% en él. Sin embargo, en IE, tenemos una página en blanco. Esto es un problema si desea cargar datos de clientes en un gráfico b / c a veces no tendrá otros puntos de datos todavía, y usted puede tener sólo 1. Hay algo que podemos hacer para arreglar esto.

Comentario de chuck Pearson el 03/26 a las 11:20 AM

Lo siento significaba reemplazar no coincidir

@ Sven: Gracias. Me alegra que te guste. Mientras una API de lienzo del futuro IE siga el estándar, debería ser una transición limpia. Usted nunca sabe con IE sin embargo ... :)

@Alexandre: Gracias por la retroalimentación. Creo que su primera sugerencia ya está en el rastreador de incidencias (http://code. google. com/p/dwpe/issues/detail? id=8). Para su segundo problema, es posible que pueda utilizar la opción yLabelInterval para obtener lo que necesita, pero también puede cambiar la parseDirection según su conjunto de datos. Su idea para un xLabelInterval es buena. Le importaría agregarlo al rastreador de incidencias como un problema de mejora? Por último, no se recomienda quitar la tabla de la página, ya que incluso cuando el gráfico está presente, la tabla proporciona una versión accesible de los datos para usuarios ciegos. Dicho esto, si sólo está pidiendo una opción para agregar automáticamente la clase "accessHide" a la tabla, que lo oculta fuera de la página, que suena como una buena idea, y sería fácil de implementar. Te importaría agregar un problema al rastreador para eso? ¡Gracias!

@Graham: Buena idea. Si puede ingresar eso en el rastreador de incidencias y adjuntar un parche, echaremos un vistazo e intentaremos incorporarlo al origen si cumple con un caso de uso común. Incluso si no lo incorporamos a la fuente, alguien más puede encontrar su parche útil allí. ¡Gracias!

@Chuck: Suena como un error. Te importaría presentar un problema en el rastreador? Entonces nosotros o quizás otra persona puede echar un vistazo. ¡Gracias! http://code. google. com/p/dwpe/issues/list

@Reed: Después de crear su gráfico, sólo dé a la tabla una clase de "accessHide" y será accesible oculto de la vista. Prueba esto:

Var myTable = $ ( 'tabla # mydata'); MyTable. visualize (); MyTable. addClass ( 'accessHide');

Comentario de Scott (Filament) el 03/30 at 10:17 AM

Esto parece realmente prometedor! Es genial que use una tabla en la página para generar los gráficos. Éste era uno de mi requisito al considerar los conectores de los gráficos de jQuery. Sin embargo, tengo una preocupación con respecto a uno de los ejemplos; El ejemplo del gráfico circular proporciona información agregada que no está disponible si el Javascript está desactivado. El complemento compila el número y genera un porcentaje que puede ser difícil para algunos usuarios. Sería mejor tener una segunda tabla con la información compilada que se utilizaría para el gráfico circular.

El gráfico circular también se puede utilizar para presentar un número y un porcentaje al mismo tiempo de una tabla. Considere este ejemplo ficticio sobre la representación de la primera lengua de una población del país. Aquí es cómo podría verse la tabla:

Primera Lengua de los ciudadanos en FictiveLand

Idioma: Inglés Número de ciudadanos: 2 000 000 Porcentaje de ciudadano: 50%

Idioma: Francés Número de ciudadanos: 1 200 000 Porcentaje de ciudadano: 30%

Idioma: Español Número de ciudadanos: 800 000 Porcentaje de ciudadanos: 20%

Comentario de Laurent Goderre el 03/30 at 01:26 PM

@ Laurent: Buena idea. Eso sería una buena manera de proporcionar una versión accesible de los porcentajes de pastel. Actualmente estamos elaborando una forma de trazar un subconjunto de las columnas o filas de una tabla, lo que le permitiría visualizar esa segunda tabla como un pastel, diciéndole que simplemente ignorara los datos de la columna%. Con el script actual, puede considerar agregar el% dentro del TH con el nombre del idioma (Language: French (30%)). No sería tan agradable como tener una columna separada, pero podría proporcionar una solución hasta que implementar la nueva característica ...

Comentario de Scott (Filament) el 03/30 at 01:42 PM

Cualquier idea sobre cómo solucionar nuestro problema.

Comentario de chuck pearson el 03/30 a las 14:40

@chuck: en un comentario anterior, le pregunté si no le importaría presentar un problema en el rastreador de este problema. Lo siento si fue enterrado entre otras respuestas. Es más fácil corresponderse acerca de los insectos particulares de allí. Http://code. google. com/p/dwpe/issues/list Por favor, especifique si el problema ocurre con celdas que tienen 0 para un valor o si está hablando de celdas que no tienen ningún valor. Adjuntar o vincular a una página de prueba sería una gran ayuda también. Gracias.

Comentario de Scott (Filament) el 30/03 a las 14:50

Oh genial, no lo vi. Lo haremos y les agradezco que echen un vistazo. Creo que nuestro desarrollador líder, Lance, lo publicará mañana.

Comentario de chuck Pearson el 03/30 a las 06:23 PM

Hasta ahora he utilizado protovis y flotr para visualizar gráficos web, pero mis primeras pruebas con su complemento parece prometedor, ya que realmente acelera el desarrollo. Qué necesitaría para introducir una tercera dimensión utilizando el enfoque de gráficos apilados? Vimos que agregar un valor a una celda separándolo por coma (como 190,10) no rompe el gráfico, pero crees que tu código es un buen punto de mira para implementarlo? Gracias Scott & amp; filamento;

Comentario de geraldo el 03/31 en 05:05 PM

Huh? Opera lo soporta desde las edades.

Hola. Esta es mi pregunta Cuántos caracteres en una web es posible visualizar, porque traté de utilizar en IE y lo hizo pero me muestran msj: el script en esta página causa que IE ejecutar lentamente quieres ejecutar este script?

No sé cómo puedo arreglar? Puedes ayudarme?

Comentario de ixio el 20/04 a las 11:00

En primer lugar, gracias por una excelente biblioteca gráfica! Ya ha resuelto muchas de mis necesidades, pero por desgracia, estoy atascado en un problema de renderizado en IE.

Estoy usando la biblioteca de gráficos para procesar las estadísticas de días en un mes determinado. Si tengo estadísticas por sólo uno de los días, y 0 para todos los demás, IE no mostrará ninguna barra. Si reemplazo '0' por 'null' o 'nbsp' por los días sin estadísticas, estoy recibiendo una barra que empieza correctamente, pero termina como una barra diagonal hacia la esquina inferior derecha.

Este problema no es un problema en los navegadores que admiten el elemento canvas. Si usted tiene sugerencia para una solución, yo estaría muy agradecido!

Comencé a trabajar en este gráfico y debo felicitarlo por el código limpio y conciso. Increíble plugin.

Estaré trabajando en más funciones, y también pretendo añadir una capa de interacción. Todavía no lo sé, pero creo que esto debería hacerse como un complemento separete. O por lo menos como una capa separada, así que uno podría utilizarla sin la interacción y la ganancia en el tamaño del byte.

Mi trabajo inicial fue implementar puntos en la línea y gráficos de área.

Sory por no usar SNV en Google Code. No es lo suficientemente ágil para el tiempo que tengo.

Hola, empecé a usar este plugin es muy bueno, pero tengo un problema con el gráfico circular cuando un solo elemento tiene 100% en IE no se coloca al 100% al elemento correspondiente, por ejemplo, color: Rojo - 100% púrpura - 0% Azul - 0%. Pero el gráfico circular mostrado en IE: Rojo - 0% púrpura - 0% -100% azul. Necesito usar esta tabla, y el único problema que tengo es esto. ¡Ayuda por favor!

Comentario de Erubire el 29/04 a las 11:25

Sólo una corrección: Rojo - 100% púrpura - 0% Azul - 0%. Pero el gráfico circular mostrado en IE: Rojo - 0% púrpura - 0% azul - 100%.

Comentario de Erubire el 29/04 a las 11:28

Estoy trabajando mucho para mejorar este plugin para la interacción y para apoyar algunas nuevas características. He subido una demostración con mi código más reciente aquí:

Me gustaría aquí algunos comentarios (a través de github mensaje o comentario es muy bien) y, especialmente, del propio grupo de relleno. He hecho algunas opciones de arquitectura por mi cuenta y una gran cantidad de reescritura de código para mejorar el rendimiento, una mejor reutilización de código y apoyar plugins para mejorar la jquery visualizarse (sin mencionar la interacción en sí). Si los cambios que he hecho no son bienvenidos, puedo volver a escribirlos o puedo cambiar el nombre de mi fork para usar otro nombre de plugin y espacio de nombres. Sólo házmelo saber.

Espero que a todos les guste! =)

hello, this is my question how many chars in one web it’s possible to visualize, because i tried to used on IE and it maked it but show me msj: the script on this page cause that IE run slowly do you want running this script?

@Irae: awesome work! We love what you’ve done with the script. We haven’t had the time to fully look through your changes, but the demos look excellent. Any chance you’d like to collaborate further on some of the other features/bugs in our tracker? In the near future, we may move the official development of this plugin over to Github as projects seem to attract more contributors there. Thanks again and we’ll be sure to take a deeper look at the code very soon.

@Batıkent: We’re not sure on the upper limit of rows that Visualize can handle in a reasonable amount of time in IE. If you’re seeing some performance problems, you might consider checking out @Irae’s fork on Github, as it looks like he’s made a number of performance improvements.

Comment by Scott (Filament) on 05/27 at 08:52 AM

@Scott: Most of the enhancements I’ve made are for one project at work. I’ve reached our current milestone and will have to stop developing for some time. Later this year I will have another milestone that will need further development on the plugin, I plan to fix some of the issues on your bug tracker at that time. Also, Github is awesome for code collaboration, if you migrate your code, I can update my fork to point to yours, so my changes could apear on your fork queue.

@Batıkent: My improvements to performance are most focused on less DOM querying, witch is part of IE’s performance issue. The second part is that the whole querying, html insertion and graph drawing are done in one take. I’ve optimized the code so this steps can be separated, but I haven’t the time yet to separate them. I intend to do so and provide a loading message to the user. This can be done with postMessage in browsers that support it (IE8, FF3+, etc), and setTimout on the older ones, but I can’t promisse when I will have time to do so.

@Iraê, @Scott—I’m really impressed with the Visualize plugin so far. I’m working on a pretty big Drupal project that I’d love to and am planning on using Visualize with, and would love to contribute whatever I can coming out of the work on that project.

But now I’m faced with a conundrum—which version to use and contribute back to?

@David: It sounds like @Irae has made some great improvements, and from a quick a glance, the code organization appears to optimized as well. If that version has all the features you need (does it have charting of table subsets yet, for instance?), it might be a better starting point for you. We’ll keep track of updates on Git and at some point, merge all the good bits into the official source. In short, grab whichever one appears to be best for you and contribute away! We appreciate the help.

Comment by Scott (Filament) on 05/27 at 12:12 PM

@Scott—I suspected as much. The big win for me is the x-axis scaling and manipulation that is going in (all of which is freakishly recent). My application is a lot more “number-y” than the current version of Visualize would allow (as far as I can tell… I’m just getting started). In all events, features like scaling on the x axis are going to wind up being important for me.

I just don’t want to contribute to a split between the code bases, especially given how much I appreciate the work everyone has done to date—conceptually, visualize works exactly as I hoped.

@Scott, David: The only thing I’ve not merged so far was the table subsets. I’ve not merged it because the selector was being run even for full tables. It’s really straight forward to re-add this feature using some conditionals, specially now that I’ve moved all the DOM querying to a single place on the code. The other bugfixes and features are already merged into my version.

@David: Great to hear that you are willing to contribute. I second Scott here. Pick the version you think it more like to work to you. I’ve not commented much on the code and not documented all new features. If you have any questions regarding my code, just send me a private message at Github and I will gladly help. I’ll try to update the documentation and add one or two more examples to better illustrate the features.

@Iraê: For me, the table subset is not an important piece of functionality. On the other hand, being able to add a scatter plot chart type and use numerical values and control x-axis scaling and other properties is a very important piece of functionality.

@Scott, @Iraê: Thanks again, both of you.

Thanks for this plugin - so far it’s been fantastic in the compatibility and customisation stakes (as far as styling goes). There are a couple of things that seem like they’d be relatively simple to fix, but would make a huge difference to functionality for me:

1) The ability to specify the width of the canvas in the stylesheet instead of inline CSS as generated by the js:

- I have a necessarily fluid layout - very wide tables with width set at 100% - it would be fantastic if I could have a fluid-widthed graph/canvas as well.

- As a compromise, I’ve made my canvas

900px wide to optimise in 1024x768 resolutions, but this means printing in IE is broken - the graphs are too wide/cut off.

2) The ability to either customise the legend in the stylesheet, or at very least changing the legend from being displayed by a background colour to a border or somesuch (eg make it 1px #000 background, with border:6px solid #000?)

- My need for this is in the nearly-perfect rendering of the graphs when I print - the only thing missing is the legend, as background colours are by default turned off for printing in most browsers. CSS borders, however, still show up. So, a legend that looks practically the same but constructed of a very thick border around a single pixel would work wonders for me (just an idea - would gladly submit to any other solution that worked!).

I started working on this, but then I found Flot (http://code. google. com/p/flot/ ). Flot is already architected the way I was starting to re-architect this plugin…

Hello, I’m not JavaScript educated and could use a working example. tried copying the code locally including all the. js and. css files and updating the paths but no data is showing up in the first three examples and only the numbers with percent are displaying on the piechart.

Can you email me a text file working example? All I need at this time is the bar graph, but all will be useful.

Hello :) and thanks for that great code a question. is there a minimum data figure for the JS not to run stupid. just made an simple stupid familial application for the Mundial “Bets” here in Peru. all is fine fine. 13 players trying to make an European version for my friends back there in Belgium. under 8 (if I do remember well) just turn FF to run in the deep emptiness. any issue. Consejo. thanks any way Pat

Comment by pat on 06/15 at 10:45 PM

Thank you so much… that the great plug code.

Comment by karim on 06/17 at 09:21 PM

I’m using percentages as the values and they’re generally between 2% and 5%, if the top value for the y-axis is 1.91%, I get y-axis labels of 0, 1 and 1.91. Is there any way of rounding off the top y-axis value to 2 in this case. So the bar graph for the 1.91% level wouldn’t go all the way to the top as the top y-axis label would not be 2?

Thanks for a really great plug-in!

Comment by Richard on 07/04 at 02:04 PM

Never mind, i figured it out thanks,

I added the following to line 91 of visualize. jQuery. js within the topValue: function()

I’ve nested tables in a tab as:

<div id="Tab1"> <table> <tr> <td> <table id="data"> <caption>#caption</caption>

If the #data table is moved to the top level then $(’#data’).visualize() renders the chart correctly. However with the above code fragment, $(’table #data’) or $(’#data’) seems to show no results. <div> is rendered into a tab.

Any idea on how I can use the visualize plugin to render charts for nested tables.

The plugin is working fine in Firefox but it acts really weird. First it didnt show up at all because I forgot the excanvas. js file but when I added it, it rendered it without colors and in a small corner of the graph. Has anyone ever encountered this problem before?

Comment by Laurent Goderre on 09/15 at 11:25 AM

Another comment I would make is about the optimization of the CSS. It would be easier to maintain and to change the style if most of the styles were move from the dark and light CSS to the main CSS and have the dark and light them only specify the color. Currently, if you use either the dark nor the light, it looks really weird.

Here’s how it would look like

Andrew if you look on the url under my previous post you can try my circlediagram in your browsers, because at my end everything is just working fine.

Ante todo. GREAT plug-in. Very easy to use, customize an deploy. I am using this in a reporting tool I’ve built at work and it’s going to work out very well.

I did, however find the need for more control over styling when trying to use multiple charts on the same page. I added a bit of code to the plug-in to essentially add a class to the generated chart. I called the variable ‘chartName’ which would serve as an identifier as well as a class for CSS styling. There may already be method built into this project that allows for this, but I was unable to find it, so if anyone has any other suggestions then i’d be happy to hear them. Otherwise, I’ve found this to grant me a fair amount of control and I’m seeing success so far. Here are the steps I took:

In the “visualize. jQuery. js” file:

Add this option to ‘o’ (options) variable near the beginning of the plug-in: `chartName: null,`

Add this to each chart type function in the ‘createChart’ variable: `canvasContain. addClass(o. chartName);`

Then add the ‘chartName’ option to the call to the chart when you instantiate the plug-in: `$(’#rateTrend’).visualize(

I’ve been at this for just a few hours this morning and here is a sample of what I have so far:

Hi Guys, I just have a quick question about the how the charts would handle <tfoot> data wounf this be added in as a footnote to the chart? as you can probably tell i haven’t tried this yet but thought id ask as the sit i am planning to use this on has lots of data tables and may have important footnotes. many thanks for sharing all your hard work with us

Thanks David ps if i have missed somthing please feel free to correct me.

sorry one more thing some of the data Im working with has £(£) inthe table cells as it is financial data but this seems to breack the chart.

OK one last think promise Where are you hiding the links “View low-bandwidth version” in the code as i have many tables on the one page and the text in the link is not meaningful when taken out of the context of the page. Thanks for putting up with me.

This was one of my requirement when considering jQuery graphs plugins. However, I have a concern regarding one of the examples; The pie chart example provides aggregated information that is not available if javascript is turned off.

David, I’ve faced the same issue. Here’s an option for enhance. js:

enhance( appendToggleLink: false, // default is true. see enhance. js loadScripts: [ . snip. >);

Oh great, I didn’t see it. We’ll do that and I appreciate you guys taking a look. I think our lead developer Lance is going to post it tomorrow…

Comment by zerocool on 01/24 at 09:47 AM

Hi, i just started learning jQuery and now i’ve my first problem: I’m looking for the possibility to show the values on top of a bar, similar to the percent on a pie, but just the value from the table. If there is a 12 in the table it should be the same on top of the bar. Please, can somebody explain (and perhaps demonstrate) how to realize it.

Is it possible to give a “fluid” width to charts? I mean, i’ve got an admin panel with two columns, and widgets into them… Depending on the screen width of the client, these two columns can be very large or very small… And I need to put charts into widgets… So, how can I tell Visualize to adapt width. Thanks in advance for your answers.

thanks very good ordu

thanks very good hok

First off, awesome plugin!

FWIW, I was able to successfully implement this plugin for a project I am working on once I changed every reference from “canvas. width()” to “canvas. attr(’width’)” and the same for height. Without this fix, the chart background and title would render, but all data and labels were stacked on top of each other due to the “bottom” CSS attributes all being 0 (which stemmed from the canvas width error).

If anyone could provide insight as to why this occurred or if anyone wants screenshots, let me know.

I’ve started using visualize for a couple of calculators. I’m also playing around with Iraê’s version.

I do like the interaction but I’m having trouble getting everything styled. I’ll probably play around with it and contact Iraê about submitting any meaningful changes.

That is soo cool! I wish there was a wordpress plugin which could do this straight from tables. Does anybody know if there is any? All my search attemps have been unsuccesful, leading me only to this page but not a single plugin which can do this.

Comment by SorinNedelcu on 06/04 at 03:36 PM

i love the plugin. but what i would love even more would be a parameter representing a range for the x and y values. When you visualize a table with only high values which don’t vary much you get mostly free space until the actual graphs. The best would be to implement x/yRange parameters which allow specific values for the range and dynamic ones would be nice too. So if I have values from let’s say 80 - 100, you could say yRange[ 75,105 ] and the graph would start at 75 and not 0, thus providing more detailed graphs due to lack of the whole free space. Even better would be the option to say yRangeDynamic: 10% and it leaves 10% space above and below the graph.

Comment by NetCrack on 06/04 at 09:02 PM

during further research i stumpled uppon the issue on the google code issue tracker, where a guy called mr. teecee posted a nice snippet to solve the problem, thank him very much btw: http://code. google. com/p/dwpe/issues/detail? id=8#c6

Comment by NetCrack on 06/05 at 05:16 PM

I noticed in both visualize-dark. css and visualize-lite. css files have styles being applied to global elements like so:

No big deal as this can be edited down to only effect the charts but recently got the updated version and the above styles had to be edited again.

Just wondering if body is neccessary and if it would be possible to edit the source files so that all the table stlyes apply to only classes and ids used on chart elements.

This way it wouldnt be necessary to edit this css on every update.

Other than that Great work!

Comment by justclint on 06/17 at 05:20 PM

Im new to jQuery, so please forgive my noob question. Can someone tell me how to apply graph to a single table? My page consists of several tables, among them I want to chart a specific table by providing ID. Can someone help me plz?

Comment by Vyas on 06/24 at 02:26 AM

@Vyas: Add an ID to your <table ID=’HTMLTable’> and then use the ID when calling visualize() $(’#HTMLTable’).visualize()

EASY PIE CHART

Lightweight jQuery plugin to render and animate nice pie charts with the HTML5 canvas element

View the Project on GitHub rendro/easy-pie-chart

easy pie chart

Easy pie chart is a jQuery plugin that uses the canvas element to render simple pie charts for single values. These charts are highly customizable, very easy to implement, scale to the resolution of the display of the client to provide sharp charts even on retina displays, and use requestAnimationFrame for smooth animations on modern devices .

Browser support

This plugin supports all major browsers that support the canvas element. With excanvas you can even render the charts on IE 7+8.

Get started

To use the easy pie chart plugin you need to load the current version of jQuery (testet with 1.7.2) and the source (css+js) of the plugin. You can also use bower to install the component:

Then just add the following lines to the head of your website:

The second step is to add a element to your site to represent chart and add the data-percent attribute with the percent number the pie chart should have:

Finally you have to initialize the plugin with your desired configuration:

Configuration parameter

You can pass a set of these options to the initialize function to set a custom behaviour and look for the plugin.

It is simple to create a number of different types of pie charts in Flot. I’ve provided examples of various Flot pie charts below.

For a more in depth introduction to Flot and how to use it in your web pages, take a look at the tutorial how to add charts to your web pages using Flot.

The code for all of the pie charts shown in this page is quite similar, so to save space I will only provide the full code for the first pie chart (don’t worry – it is easy to create other pie charts from this):

You will see that the data in all of the pie charts is the same – see the data in the above code.

To create each pie chart, just replace the code inside $(document).ready(function() ); with the code next to each pie chart.

In addition to this, the width and height of the pie charts varies slightly. I’ve included the width and height for each pie chart next to the chart. Replace the CSS in the above code for #placeholder with the CSS next to each pie chart.

Note that you will need to include the pie chart plugin – include jquery. flot. pie. min. js underneath jquery. flot. js in the head section of your HTML document:

Pie Chart with a Legend

Pie Chart with Labels Instead of a Legend

Pie Chart with Coloured Labels

Flot data format

We`ve learned about how to make a basic line chart in the last chapter, so in this chapter we will talk about the most important part - data format, beofre you make any charts it`s important to make data in the right format that Flot needs, if the data is incorrect or not in the right format, the charts will not come out right. This chapter is all about the data parameter for calling $.plot.

Basic data format

Flot data format is consist of multiple data seires array, like the following format.

And each data series is consist of values of x axis and y axis.

Put it all together, Flot data will be the following format.

Below are the correct data formats

In addition, the values of x axis and y axis must be number format(integer or float), no string format allowed, even if you`re using time series format data, you have to convert into javascript timestamps, that is, milliseconds since 1/1/1970 00:00:00 UTC. You can also use null value in Flot, if value of a data point is set to nulll, that particular data point will be ignored when drawing.

Below shows how to take parameters into function when calling $.plot (label attribute can be omitted, but data attribute must be specified)

Bar chart with null value

Time series data format

If you`re using time series format as data, In addition to convert time into javascript timestamps format, you also need to set axis. mode value to "time" in the options, and include jquery. flot. time. js plugin, below shows you how to use time series.

Time series line chart

Multiple data series format

Data formats we mentioned above are all have single data seires, but there are times that we need to use multiple data series, the following code shows you how to do it.

add more data series subsequently if needed

Mutiple data series chart

Bar Charts / Basic usage

Descripción

The Kendo UI chart is a data visualization widget which allows you to output a graphical representation of your data. It is useful when you would like to utilize modern browser technologies such as SVG or Canvas (with a fallback to VML for older IE versions) for interactive data visualizations. The chart supports various chart types such as area, bar, line, scatter, pie and donut, etc. as well as stock (OHLC).

A Bar chart displays data as horizontal or vertical bars whose lengths vary according to their value. You can use a Bar chart to show a comparison between several sets of data (for example, summaries of the unique and total site visitors for certain period).

To instantiate a Kendo UI chart, you need to specify an empty div with an id on the page, select this div with a jQuery selector and invoke the kendoChart() function. As a result, the chart is registered as a standard jQuery plugin.

The chart can fetch data for its series from either local or remote data source. It can also use the Kendo UI DataSource as a mediator for processing data.

Additional information about how to use the Kendo UI chart widget can be found in this section of the product documentation.

How to Use Google Chart Tools with Web Applications

Google Charts makes it easy to show data visually and beautifully. You can show historical trends or by categories. Depending on the data your site gathers, you can show which users have the best reputation, which products sell best, or which topics are most active. You can display data with pie charts, bar graphs, or area charts. You could even display a map showing the importance of each country or city when looking at the number of users or the amount of time and money they spend on your site.

Want to take advantage of these cool capabilities? In this article, I show you the process.

How well is your site doing? What can you tell about your users and how they use your site? In the era of Lean Development, we developers (and our bosses and clients) want to know more about what our website is doing, how well it’s doing it, and how the users are using it. Ideally this guides us in selecting features to emphasize, where to focus development efforts, and when to perform system maintenance.

Nothing beats visualization to show us what we need to know at a glance. This is where Google Chart Tools come in: making pretty pictures out of often-dry data. The tools offer a variety of charting options, from the ubiquitous bar chart to the “geomap,” a map showing the relative importance of each country or state.

Just a little taste

Google Chart Tools can be quite powerful, but we can start with a simple chart quickly. Here is an example of the HTML and JavaScript code to create a basic pie chart:

This gives us the following chart using data from NPR as a data source:

There are two important parts in the sample above: the <div> that holds the chart, and the code that generates it.

The first script is the Google Loader. which lets you use JavaScript to decide which pieces of the various Google APIs to load, instead of having to sprinkle your page with <script> tags. Google Loader also loads the scripts asynchronously, so the whole page loads faster. In this case, we load the basic JavaScript classes, data structures, and code that implement the core aspects of visualization, and “corecharts,” a package that contains the basic chart types.

You can also load each chart type individually if want to minimize resources on the client’s system. Loading “corecharts” means I can change chart types easily, without changing the load statement. During the exploration phase of development, I like to optimize for programmer time. This way, I can change the line

and get a different chart:

In this case, the obvious and possibly redundant chart of choice is clearly the pie chart.

Loading data

Google Chart Tools uses a DataTable JavaScript object to hold the data to be visualized. There are a number of ways to create and populate this object.

As we saw in the example above, the easiest way is to convert an array to a DataTable. Actually, we start from an array of arrays. The first element of the array is the header line, an array of strings. Every element after that is an array of values. For our pie chart, these values are a string and a single numeric value. Other chart types (such as line or bar charts) work with more values, representing each column with a different color line or bar, or bubble, etc. The first element of each data row is the label, and it’s often a string or a timestamp.

For an example with multiple values, let’s graph the average snowfall per month in a few American cities:

which, when put in a bar chart, gives us:

You can also create and populate the DataTable by hand. You instantiate the object with new (as you would other JavaScript objects), then use addColumn() for each column of data, and addRow() or addRows() to add the actual data. This way of specifying the data gives you more flexibility on some of the aspects of the charts generated. For example, if your data contains dates or the time of day, calling addColumn and specifying the data type makes sure the data is displayed correctly.

With this method, you can also generate the content dynamically, rather than work with a fixed dataset:

Finally, the most powerful way to populate the DataTable object is to load it from a remote source, using AJAX. Unfortunately, pulling the data from AJAX requires a little bit of work; there is no simple method you can call and let the magic happen, so you need to write a bit of code.

AJAX, as you already know, means “Asynchronous JavaScript and XML.” There’s the dreaded word: asynchronous . Asynchronous programming isn’t always easy. It almost always requires callbacks, which can get confusing. In the examples so far, we already use a callback, to tell the Google API to fire off the drawChart() function once all the library pieces are loaded.

Now, we have to insert a step between that moment and when we draw the chart. In this new step, we load the data we want to use through an AJAX call, and pass the data to our drawChart() method.

If you are testing this code by loading the HTML file from your own computer, without using a Web server, you may not be able to load the JSON file without jumping through some hoops. Some browsers do not let you load files through AJAX when the document is loaded locally. If you are using Chrome, you must start it from the command line with the --allow-file-access-from-files parameter to get around the restriction. With Internet Explorer, you need to change

to get the same result. Safari and Firefox let you load the document happily, but they do not set the xhr. status to 200 (which makes sense; seeing how the document wasn’t loaded with HTTP, it should probably not return an HTTP code).

This is why I checked that xhr. status is either 200 or 0 in the onreadystatechange function/callback. Normally, you only want to proceed with drawChart if the status is 200 . but we’re just playing with our chart for now, so we can relax the rules a bit, right?

The last step to make this work is a data file called countryPopulation. json which looks like

and we get this very pretty picture:

JSON data into the DataTable ourselves, the actual format is not that important. We only need to write the code that turns our format into calls to build the DataTable. One common format has metadata at the top level of the JSON object, and an array that holds the data. In that case, the call to draw the chart would look like

Why would you want to go through all this trouble to fetch data through AJAX? You can just generate it into your HTML page with JSP, PHP, etc. so why the extra trouble? It all depends on the nature of the data. If all you have is a flat data file that’s never updated, then the only reason to use AJAX is because you like doing the programming equivalent of playing in the mud: It’s messy, but it’s fun. Where it becomes useful is when the data is dynamic. You could, for example, have files representing your company’s sales over the last 10 years, and you load the file corresponding to the year the user selected. Another advantage is that by fetching data through AJAX instead of loading a whole new page (which you would have to do with JSP or PHP), the response is much faster if you load additional files of data, say in response to user interaction.

Where using AJAX gets even more powerful is when, instead of loading a file, you call a web service that generates the data for you, likely from a database. That service may take parameters to refine the data, such as a date range, or the flavour of cupcakes sold, or the demographics of the user who tried a new feature on your site.

There is one more way to load data into your chart: You can get the data from the cloud. You can query a Google Spreadsheet or other data sources that support the Chart Tools Datasource protocol. That is beyond the scope of this article; see the documentation for details.

Back end support for AJAX calls

If you have control of the application’s back end, you can devise the web service that generates the data to be as powerful as you need. When deciding what to graph, consider the data you already have, and the data you can collect. Ask yourself how you may arrange that data to tell a story, or try to find fun questions to ask of it. If you recently implemented a new feature to send email reminders to users, who has set up more reminders, men or women? Younger or older users? Do users with a gmail. com address spend more money on your site than users with a hotmail. com or yahoo. com address? You may find that you want to record more information about your users’ behaviour, but you can likely start with what you have. Once your boss or client sees what you can do, it will be easier to get additional development approved.

When crafting the database queries to answer those questions, make sure you set up some reasonable default date ranges. That way, if the user did not ask for a specific time frame, you don’t tally all the data ever gathered, much of which is probably not relevant anymore. Also consider your tables and indexes; your schema may benefit from an index that starts with the date/timestamp you query on. You usually want the timestamp as the first (or only) column in that index, since that lets the database exclude the most data faster. This is particularly relevant as time goes on, since you’ll have more and more data.

If your queries use more than one table, be sure to optimize for the join condition too. The speed of execution of the queries becomes more important as more people use your cool new charts more often. As in all things, however, consider the place of these queries in the whole system, and optimize for the overall good of the system.

To group data per day of the week or hour of the day, you need to refer to your database’s date handling functions; they tend to differ between database engines. For example, in MySQL, I found out which days were more lucrative for my clients with

select dayofweek(date), sum(amount) from transaction group by dayofweek(date);

Manipulating data on the client side

You don’t have access to the back end to create a data service? You don’t want to spend your server’s precious cycles computing data for pretty pictures? You just don’t have enough data to bother? That’s okay; you can also process the data on the client side.

The DataTable object in the previous examples is the basic object used to represent chart data. It is a mutable list of rows of data, with each row organized in columns of predefined format. You can add columns and rows programmatically or change the values in the cells (at a specific row and column). Redraw your chart to show the changes.

The DataView object is another way to pass data to the chart. Like a database view, it represents a specific “take” on the data in a DataTable . You can use the DataView to hide columns or rows, to filter the rows, or to sort them. You can also use a DataView to add computed columns. For example, tally the results of a bake sale where the students decided on the price of the baked goods. Given a DataTable with the number of items sold and the money earned by each student, you can also chart the items’ unit price. We can choose to display only the students who sold at least 10 items, by first getting a list of the matching rows (from the DataTable ) using the getFilteredRows() method, and passing it to the DataView ’s setRows() method.

While you can modify an existing DataTable to add computed columns and perform other manipulations, using the DataView lets you leave the original data unchanged. To add controls next to the chart to change filter options or to hide and show columns, you can just create a new view and redraw the chart. It also means that you do not need to duplicate all the data each time you change the chart’s parameter. Your users (or at least their browsers) will feel better for it.

Another way in which you can effectively manipulate the data is by adjusting the axes on your chart. By default, the Google Chart Tools find the best range for the axes by looking at all the data being charted, and making sure it all fits nicely. But you can override that setting by providing minimum and maximum values for the axis, or by requesting that a logarithmic scale be used, if the data warrants it.

In our bake sale example, if we were to chart the total amount earned by students on the same scale as the unit price, we would barely see the unit price, as it’s so small. What we can do is set up a second axis, and assign each data series (each column) to one axis or the other.

Our last example shows some of these client-side manipulations:

Presentation Options

We have seen a few of the chart types available. You should look at the documentation and the playground to see all the options.

There are two implementation styles. All the ones I showed you use SVG or VML to create the chart. That is, the chart code modifies your document’s DOM to display the chart. This makes it possible to interact with the DOM elements in the chart to show additional information. Chart types using this implementations are those Google recommends and maintains.

The other implementation style, “images,” gathers all the data, and uses it to call a Google service to generate an image file representing the chart. ImageBarChart . ImageLineChart . and ImageCandlestickChart are examples of this implementation style. Google officially deprecated them last year, but they remain available. If you really want to use these charts, review their deprecation policy first.

You can style your chart by selecting its size and color (or colors), and passing those as entries in the options object you pass to the chart’s draw() method. Each chart type also has other parameters that can be tweaked, such as the location of the chart legend, or the part of the world visible on the GeoChart. Refer to the documentation for each chart type for the complete list of options it accepts.

With all these options, what will you chart? More importantly, what will it tell you about your site? It wouldn’t be the first time that a little bit of visualization confronts long held, yet inaccurate beliefs!

[this. series('Hello World', [60, 40])]

Provide the data values to be charted. You can create the series objects directly or you can use the series function to generate a new series object. Since an x-y line chart requires a special format for the series, you should use the seriesForXYLines function to assist in that case. Series data can also be loaded from external sources via the seriesFromCsv and seriesFromXml functions.

Each entry in the array is an object with the following attributes:

label (string, optional) the display text for this series,

data (number[]) the data values to be plotted,

color (string or string[], optional) the colour for the series - see the section on colour for more details; provide an array to specify colours for each item in the series; if fewer colours than the number of segments are given, the colours are recycled for the remaining segments,

fillColor (string, optional) the background colour between this series and the next one or a gradient or stripe definition with which to fill the current bar,

minValue (number, optional) the minimum value for this series,

maxValue (number, optional) the maximum value for this series,

lineThickness (number, optional together with lineSegments ) the width (pixels) of the line for this series,

Since 1.2.0 - color may be an array. Since 1.4.2 - fillColor may be a gradient or stripe.

Indicate how many series should be drawn directly. The remainder are still available for use with markers. A value of 0 means that all series should be drawn. The visible series must appear first in the list of series .

Specify the labels to apply to each of the data items in the series. Whereas the series labels apply to the entire series, these labels apply to all the first, second, etc. items across all the series.

Add data functions to be applied to your chart. You can use the fn and fnVar functions to assist in creating data function definitions.

Each entry in the array is an object with the following attributes:

series (number) the target series into which the calculated values are written; often this would be a dummy series ( $.gchart. series([0]) ),

data (object or object[]) one or more variable definitions for this function; use the fnVar function to create variable definitions,

fnText (string) the function to evaluate for each input value; it is specified using muParser function syntax .

Define any number of axis labels for your chart, including multiple sets of labels for one axis. Default labels range from 0 to 100 with 10 steps in between. You can use the axis function to assist in creating axis definitions and the GChartAxis functions to modify them.

_range (number[2 or 3], optional) the start and end points of the range of values depicted, which may be given as highest to lowest to invert the labels; an optional third entry specifies the interval between points in the range; if not specified a range of 0 to 100 and an interval of 1/10th the range is assumed,

_color (string, optional) the text colour for the labels; see the section on colour for more details,

_alignment (string, optional) the alignment of the labels ('left', 'center', 'right'); the default alignment changes per axis,

_size (number, optional) the size (pixels) of the text for the labels,
