Methods

setChartAttribute

Updates a chart’s attributes with a new attribute-value pair, thus updating the chart’s data definition root (the <chart> node in the XML data or the chart object in the JSON data).

This function is useful when a chart’s configuration has to be updated after it has been rendered once. The function internally retrieves the last data set for the chart using the getJSONData() method ( or the getXMLData() method, for XML data). It then updates the chart object (or the <chart> element) using the new attribute-value pair and sets this data back to the chart.

Parameters

attributes

: object or string

[+]

To set/update multiple attributes at once, an object containing all the key-value pairs is passed. In case of a single value, a string that is the key (the attribute name) is passed.

value

: string

[+]

If the attributes parameter is a single string value, the value parameter contains the value for that key.

Example

// Here we would render a chart in a DOM element with an id, say "chart-container", and upon clicking the
// chart, we would toggle the visibility of its legend.
FusionCharts.ready(function () {
    FusionCharts.render({
        id: 'salesChart',
        type: 'pie2d',
        renderAt: 'chart-container',

        dataSource: {
            chart: {
                caption: 'Revenue distribution'
            },
            data: [
                { value: '22', label: 'Redistribution' },
                { value: '54', label: 'Internal Circulation' },
                { value: '24', label: 'Sale' },
            ]
        },

        events: {
            chartClick: function (event) {
                var chart = event.sender,
                    // Check whether legend is currently visible by fetching the showLegend attribute
                    legendVisible = !!+chart.getChartAttribute('showLegend');

                // Set the opposite of the current state of the legend's visibility.
                chart.setChartAttribute('showLegend', legendVisible ? '0' : '1');
            }
        }
    });
});

getChartAttribute

Fetches value of chart attributes explicitly applied to the root chart object (or the <chart> node element).

If any attribute requested is not set for the chart or is internally computed but not explicitly set, the value is returned as undefined. For example, for multi-series column 2D charts, the default value of the showLegends attribute is 1. However, if the attribute is not included in the chart definition and its value is requested, the function returns undefined.

Parameters

attribute

: string or array

[+]

To fetch the value of a single attribute, pass the attribute name as a string. For multiple attributes, pass an array of attribute names. Values will be returned in the order of the attribute names in the array.

configureLink

Configured properties for LinkedCharts.This function accepts all properties that the FusionCharts constructor accepts. Any property passed to this function is applied to the LinkedCharts. If no properties are provided, LinkedCharts will inherit properties from the parent chart. This function lets you configure individual or multiple drill-down levels in linked charts.

The Overlay Button:

Other than the usual construction parameters of FusionCharts, this function also accepts configuration for the overlay button of LinkedCharts. When a LinkedChart is rendered on clicking a data point, a button is rendered on the top-right corner of the chart. When this button is clicked, it closes (disposes) the linked chart.

The cosmetics of this button can be configured by passing an overlayButton object as a parameter to this function. This object can have the following properties:

Button Parameter	Type	Description
`show`	boolean	Whether to show the button or not
`message`	string	Button label. Default: Close or Back
`bgColor`	string	Background color for the button
`borderColor`	string	Border color for the button
`font`	string	Font family of the button (comma-separated list of fonts)
`fontColor`	string	Color of the button label text
`fontSize`	string	Size of the button label text
`bold`	boolean	Specify whether the button label text is bold formatted
`padding`	number	Padding between the label and the edges of the button

Parameters

param

: object or array

[+]

Configuration properties for the LinkedCharts. To configure multiple levels at once, pass the level numbers as an array to this parameter. To configure the overlay button, pass the overlayButton object to this parameter.

level

: number

[+]

To configure a specific level of the drill-down chart, this parameter specifies the level number.

Default:

Example

myChart.configureLink({
    type: 'pie2d', // Set the linked-charts configuration to load all linked charts as Pie
    width: '80%', // The width of the charts would be 80% of their parent container
    overlayButton: {
        message: ' X ', // Set the button to show letter "X"
        bgColor:'#999999',
        borderColor: '#cccccc'
    }
});

// Configure linked charts to show the first level drill-down as bar chart, the next as line charts and
// the third level as pie charts.
myChart.configureLink([
    { type: 'bar2d' },
    { type: 'line' },
    { type: 'pie2d' }
]);

setChartDataUrl

Fetches chart data from the URL provided and passes it to the setChartData() method.

If the chart is already rendered, it is updated with the new data as soon as it is fetched from the URL. If the chart is not rendered, data is fetched from the URL and stored locally till the chart is rendered.

Parameters

url

: string

[+]

URL to fetch the chart data

format

: FusionCharts~dataFormats

[+]

Format of the data being fetched. If the value for this parameter is not a valid dataFormat, then the default or previously set data format is assumed.

Example

// Render a chart and fetch data from a JSON file and then when a button is pressed, change the data.
FusionCharts.ready(function () {
    var chart = new FusionCharts({
        type: "column2d",
        renderAt: "chart-container",
        dataSource: "weekly-sales.json",
        dataFormat: "jsonurl"
    }).render();

    // Assign the functionality of updating data to a button which already
    // exists in page body and has a specific Id.
    document.getElementById("data-update-button").onclick = function () {
        // Specify the new Url to fetch data from.
        chart.setChartDataUrl("average-employee-sales.json", "json");
    };
});

setChartData

Sets the data for a chart.

When this function is called on a chart that is already rendered, the chart is instantly updated with the new data. When it is used to set data for a chart before it has rendered, data is initially stored internally and is passed to the chart when it is rendered.

Parameters

data

: string or object

[+]

Data to be passed to the chart

format

: FusionCharts~dataFormats

[+]

Format of the data being passed. If the value for this parameter is not a valid dataFormat, then the default or previously set data format is assumed.

Example

// Create a chart in a page and pass data to it in `JSON` format and on click of a
// button update it with newer data.
FusionCharts.ready(function () {
    var chart = new FusionCharts({
        type: "pie2d",
        renderAt: "chart-container",

                   dataSource: {
            chart: {
                caption: "Market Share",
                showPercentage: "1"
            },
            data: [
                { label: "Current Prototype", value: "30" },
                { label: "Revised Prototype", value: "35" },
                { label: "Previous Prototype", value: "25" },
                { label: "Recalled Prototype", value: "10" }
            ]
        },
        dataFormat: "json"
    }).render();

    // Set data on the chart using the setChartData function when a button is clicked.
    document.getElementById("update-data").onclick = function () {
        chart.setChartData({
            chart: {
                caption: "Market Share Impact",
                numberPrefix: "USD"
            },
            data: [
                { label: "Current Prototype", value: "13773" },
                { label: "Revised Prototype", value: "16069" },
                { label: "Previous Prototype", value: "11477" },
                { label: "Recalled Prototype", value: "4591" }
            ]
        }, "json");
    };
});

getChartData

Fetches the data set for a chart, in one of the valid dataFormats. The function needs to be called on an existing chart. If called on a chart that has no data, it returns an empty chart object for json data, an empty <chart /> node for xml data, and an empty string for csv.

Parameters

format

: FusionCharts~dataFormats

[+]

Format in which chart data has to be retrieved

Example

// Render a chart and upon click of a button alert the chart's data in
// CSV format.
FusionCharts.ready(function () {
    var chart = new FusionCharts({
        type: "column2d",
        renderAt: "chart-container",
        dataSource: "weekly-sales.json",
        dataFormat: "jsonurl"
    }).render();

    // Assign the functionality of retrieving and alerting CSV data to
    // click event of a button
    document.getElementById("alert-csv-data").onclick = function () {
        alert(chart.getChartData("csv"));
    };
});

dataReady

Determines whether a chart will render properly with the data set on it. This includes data that is set using the setChartData() or setChartDataUrl() methods.

If the function is unable to determine whether data is ready or not, it returns undefined.

The function returns true or false only after the chart has rendered (the renderComplete event is triggered). The function returns false when: no data is set faulty data is set data is incompatible with the chart type; for example, single-series data is set for a multi-series chart.

Parameters

available

: boolean

[+]

Setting this parameter to true returns the status of the data, irrespective of its compatibility with the chart type. In that case, this function will return false if data provided to the chart triggers the dataLoadError or dataInvalid events

Default:

false

transcodeData static function

FusionCharts supports a number of formats in which data can be provided. Click here to view the list of formats supported. This function allows data to be transcoded from one supported format to another, without initializing a new instance of FusionCharts. It is very useful when you already have a set of data stored or prepared in one FusionCharts data format and want to convert it to another format. The fact that we do not need to instantiate a new FusionCharts instance speeds the conversion process.

Parameters

data

: string or object

[+]

Data to transcode

source

: FusionCharts~dataFormats

[+]

Source format

target

: FusionCharts~dataFormats

[+]

Target format

advanced

: boolean

[+]

Request the transcoding to return data in a verbose format where it returns the conversion result along with additional trancosing information. In advanced mode, the returned data of this function is in the following format:

Property	Type	Description
`data`	object, string	Result of the transcoding process
`error`	object	Object containing the error message

Default:

false

Example

// We would convert JSON data that is already in FusionCharts data format into CSV data format.
FusionCharts.ready(function () {
    var salesData = {
        chart: {
            caption: "Harry's SuperMart",
            subCaption: "Top 5 stores in last month by revenue",
        },
        data:[{
            label: "Bakersfield Central",
            value: "880000"
        },
        {
            label: "Garden Groove harbour",
            value: "730000"
        },
        {
            label: "Los Angeles Topanga",
            value: "590000"
        },
        {
            label: "Compton-Rancho Dom",
            value: "520000"
        },
        {
            label: "Daly City Serramonte",
            value: "330000"
        }]
    };

    // Alert the data after converting it to CSV data format.
    alert(FusionCharts.transcodeData(salesData, 'json', 'csv'));
});

getCSVData

Fetch chart data set in the CSV format.

The data returned is the closest possible comma-separated value representation that has been provided to the chart. The exported data does not contain any functional or cosmetic attribute that was set on the chart. However, the following chart attributes can be set to customise the CSV output:

Chart Attribute	Type	Description
`exportDataSeparator`	string	Sets the CSV delimiter string. Default: , (comma)
`exportDataQualifier`	string	Sets the CSV qualifier string. Default: {quot}
`exportDataFormattedVal`	boolean	Sets whether the output will be a formatted string or a pure number
`exportErrorColumns`	boolean	Forces error output on the error bar, error line, and error scatter charts

For the exportDataSeparator and exportDataQualifier attributes, you can provide the quotation mark, the apostrophe, and the tab character using the {quot}, {apos} and {tab} short-codes, respectively.

This function needs to be called on an existing chart that has been loaded and has a valid data. If this function is called on a chart which has no data set on it, it returns an empty stringokay.

getDataAsCSV

Fetch chart data as comma-separated values. The delimiter can be changed by passing relevant chart attributes.

getJSONData

Fetches chart data in the JSON format. This function needs to be called on an existing chart; if called on a chart that has no data set for it, it returns an empty chart object.

setJSONData

Sets chart data in the JSON data format. When this function is called on a chart that has already rendered, it immediately updates the chart with the new data. The function can also be used to set data for a new chart.

Parameters

data

: string or object

[+]

JSON data to be set for the chart, as a string or as a JavaScript object

setJSONUrl

Fetches chart data from the URL provided, in the JSON format. When this function is called on a chart that has already rendered, it immediately updates the chart with the new data. The function can also be used to set data for a new chart.

Parameters

url

: string

[+]

Path to the JSON data file

render

Renders a chart inside a container element on a page. If the chart is already rendered, it can be re-rendered inside the same container DOM element or a different element.

Creating a chart using new FusionCharts() only creates a JavaScript instance for the chart; this function is called to render the chart. Usually, the renderAt construction parameter specifies the element on the page, inside which the chart will be rendered. If renderAt is not provided, then the container element is specified as the parameter to this function.

Parameters

containerElement

: string or DOMElement

[+]

Reference or ID of the DOM element inside which the chart is to be rendered. If this argument is not provided, it is assumed that the renderAt attribute is provided during chart creation.

insertMode

: FusionCharts~DOMInsertModes

[+]

Method for inserting the chart’s DOM element within the containerElement. Click here to read more about the DOM insert modes.

Default:

replace

callback

: FusionCharts~renderCallback

[+]

Callback function executed after the chart is successfully rendered. If the last parameter to the render() function is a function, it is treated as a callback.

resizeTo

Resizes the chart to the specified width and height. The values for the width and height are passed, in pixels or percentage, as parameters to this function. If the function is called without any parameters, it returns the current value of the chart width and height.

This function is useful in controlling the chart dimensions based on changes in the dimensions of a resizable dialog box. It is also useful in resizing charts for responsive layouts, based on device orientation change.

Parameters

width

: number or percent

[+]

Chart width to set, in pixels or percentage

height

: number or percent

[+]

Chart height to set, in pixels or percentage

dispose

Disposes a chart completely, when called on an instance of FusionCharts. This clears the entire chart object and removes it from the DOM tree structure. When the chart is successfully disposed, chartInstance.disposed is set to true.

configure

Configures status messages that are displayed while rendering a chart. For example, while a chart’s data is being fetched from a remote URL, the chart will display the message Retrieving data. Please wait.

Parameters

option

: FusionCharts~chartStatusMessages

[+]

To configure a single attribute, specify the attribute (the key) as a string. To configure multiple attributes, this can be an object having key-value pairs of all configuration options.

value

: string

[+]

If the option parameter has a single value as the key, this parameter is the value of that key.

setCurrentRenderer static function

Sets the default renderer for all the charts that are subsequently instantiated. The renderer changes depending upon the variant of charts being rendered (example: flash, javascript)

Parameters

name

: string

[+]

The name of the renderer (variant of chart rendering method) that is used.

getCurrentRenderer static function

Gets the current renderer that will be used during instantiation of new charts.

render static function

Uses a one-line argument parameter to render FusionCharts directly into the container specified in the arguments.

Calling this function directly is same as creating a new instance of FusionCharts and calling .render() on it. For example, var chart = FusionCharts.render({...}); is same as var chart = new FusionCharts({...}); ... chart.render();.

Parameters

options

: object

[+]

Chart configuration options required to create a chart. The options must include the renderAt parameter for the chart to render instantly.

callback

: FusionCharts~renderCallback

[+]

Callback function executed when the chart is successfully rendered

        dataSource: "data.json",
        dataFormat: "jsonurl"
    });
});

getXMLData

Fetches chart data in the XML format. This function needs to be called on an existing chart; if called on a chart that has no data set for it, it returns an empty <chart /> element.

setXMLData

Sets chart data in the XML data format. When this function is called on a chart that has already rendered, it immediately updates the chart with the new data. The function can also be used to set data for a new chart.

Parameters

data

: string or object

[+]

XML data to be set for the chart, as a string

setXMLUrl

Fetches chart data from the URL provided, in the XML format. When this function is called on a chart that has already rendered, it immediately updates the chart with the new data. The function can also be used to set data for a new chart.

Parameters

When called globally on the FusionCharts object, the function applies the configuration settings to all numbers on the chart.

Parameters

num

: number

[+]

Number to be formatted

type

: string

[+]

When called globally on the FusionCharts object, the function applies the configuration settings to all numbers on the chart. This parameter selectively formats numbers based on chart elements, by taking yaxisvalues, xaxisvalues, and datalabels as values.

        chart.centerLabel("The central label", {bold: true, toolText: "center label tooltext"});
    };
});

startingAngle

Rotates the pie/doughnut chart to a specific angle or by a specific angle. The mode of operation is controlled by the optional second parameter.

Parameters

angle

: degrees

[+]

Angle measure by which the pie/doughnut chart will be rotated

Default:

relative

: boolean

[+]

Mode of operation for the rotation. Specifies whether the angle being set is relative to the current angle or is w.r.t absolute 0

[+]

Hides all buttons on the chart

Default:

true

Example

// In this snippet of code, we will render a chart on a page and

               // assuming a button exists on page with a specific id
               var button = document.getElementById('print-button');
               button.onclick = function () {
                   event.sender.print();
               };
           }
       }

   });
});

exportChart

Exports a chart as an image or as a PDF document.

To enable exporting of a chart, the exportEnabled attribute (of the chart object) should be set to 1.

When exporting is done programmatically using this method, the export configuration is passed as parameters to this function.

To read on how you can export charts using the export-related context menu, click [here]tutorials/interactivity/exporting-as-image-and-pdf/introduction.md.

Parameters

The exportChart method takes the following parameters:

options

: {

exportFormat

: string

[+]

A chart can be exported in one of the following formats:

Export Format

Description

| ——— | :————-|

png Exports the charts in the high quality lossless PNG format

jpg Exports the chart in the high quality JPEG image format

pdf Exports the chart as a PDF document

Default:

png

exportFileName

: string

[+]

File name for the chart being exported, excluding the extension. The extension is automatically appended depending on the value of exportFormat parameter.

Default:

FusionCharts

exportTargetWindow

: string

[+]

When the exportAction parameter is set to download as , this parameter lets you configure whether the return image or PDF will open in the same window (as an attachment for download), or in a new browser window (_blank).

Default:

_self

exportHandler

: string

[+]

URL of the export server

exportAction

: string

[+]

Specifies whether the exported image will be sent back to the browser as download, or whether it will be saved on to the server.

Action Value

Description

| ———-| :————————|

download The exported chart image or PDF will be downloaded as file.

save The exported chart will be saved on the server.

Default:

download

exportCallback

: function

[+]

Callback JavaScript function executed when the export process is complete. If this parameter is not assigned a value, then the window.FC_Exported is executed.

Default:

FC_Exported

getSVGString

Fetches the SVG of a chart, created by FusionCharts while rendering the chart, as a string.

lockResize

Controls a chart’s automatic resizing ability when its dimensions are in percentage. This function has to be called before a chart has rendered. Using the hasRendered() method can be useful here. If the lockResize() function is called without a parameter, it returns the current state of the resize lock.

Parameters

state

: boolean

[+]

Setting this parameter to true will lock the automatic percentage-based resizing. If resize is already locked, sending false unlocks it.

showChartMessage

Shows a text message on a chart.

Parameters

text

: string

[+]

Text message to be displayed

modal

: boolean

[+]

Boolean value to indicate whether the message will be shown on an overlay button or on the chart.

Default:

false

cancelable

: boolean

[+]

If set to true, the modal can be closed by clicking. Defaults to false.

Default:

false

zoomOut

Zooms out the zoom line chart by one level.

zoomTo

Zooms the zoom line chart to view a specific range of data.

Parameters

startIndex

: number

[+]

Index of the data point starting at which the chart will be zoomed into

endIndex

: number

[+]

Index of the data point until which the chart will be zoomed into

resetChart

Resets all the zooming, panning, and pinning actions performed on a zoom line chart.

setZoomMode

Switches between the zoom mode and pin mode of a zoom line chart programmatically.

Parameters

yes

: boolean

[+]

Set to true to activate the zoom mode, set to false to activate the pin mode

getViewStartIndex

Returns the index of the first visible data point (in order of its definition in the source data) on the canvas of a zoom line chart.

getViewEndIndex

Returns the index of the last visible data point (in order of its definition in the source data) on the canvas of a zoom line chart.

getSWFHTML

Gets the HTML of SWF

addVariable

Adds variable to Flash chart. Equivalent to configure for JavaScript charts

getXML

Returns the chart configuration and data in the XML format.

setDataXML

Sets XML data for a chart, equivalent to the setXMLData() or the setChartData() methods.

This method can be called only after the loaded event is triggered. Alternatively, the setXMLData() method can be used, which does not have this limitation.

setDataURL

Sets the URL to fetch the XML chart data from.

This method can be called only after the loaded event is triggered. Alternatively, the setXMLUrl() method can be used, which does not have this limitation.

hasRendered

Returns true if the chart has rendered successfully, false if it has not.

setTransparent

Sets the background color of the container DOM element, within which the chart is rendered, as transparent.

Parameters

transparency

: boolean

[+]

Passing true implies that the chart is transparent.

getObjectReference static function

Returns the DOMElement created inside the chart container by FusionCharts. This is equivalent to accessing the DOMElement using the ref property.

Parameters

id

: string

[+]

ID of the chart, whose DOMElement is to be referenced.

Example

// Iterate on all charts rendered on a page and move them to a common location
var sidebar = document.getElementById('sidebar-html-div'), // assuming that your common container is this
    chart;

for (chart in FusionCharts.items) {
    sidebar.appendChild(FusionCharts.getObjectReference(chart).parentNode);
}

// The above can be done without using this deprecated getObjectReference method.
for (chart in FusionCharts.items) {
    chart = FusionCharts.items[chart];
    chart.ref && sidebar.appendChild(chart.ref.parentNode);
}

addEventListener static function

Listens to events across all FusionCharts instances on a page and executes custom functions when an event is triggered.

Parameters

type

: string or array

[+]

Type (name) of the event to listen to. To register the listener for multiple events in the same registration call, provide all event names as an array.

listener

: FusionCharts~eventListener

[+]

Function to be exceuted when the event is triggered. If multiple listeners are bound to an event, the listeners are executed in the order of definition, with arguments specific to the triggered event.

Example

// Show a message when a number of charts have been rendered on a page.
FusionCharts.ready(function {
    var counter = 0,
        threshold = 3;

    FusionCharts.addEventListener("rendered", function (eventObject) {
        counter++;
        if (counter > threshold) {
            alert("More than " + threshold + "charts rendered!");
        }
    });
});

removeEventListener static function

Removes the event listener(s) bound to an event.

Parameters

type

: string or array

[+]

Type (name) of the event whose listener(s) has to be removed

listener

: function

[+]

Listener function to remove

ready static function

Allows to register callback functions that are executed when the FusionCharts library is ready to be used. In general, the FusionCharts framework is ready after the DOMContentLoaded browser event has been triggered and all the initial dependent files/modules are available.

Multiple callbacks can be attached by calling this function any number of times. Callback functions are executed even when attached after the FusionCharts framework is ready.Therefore, it is recommended that all entry-point and initialization codes are written within the ready() function. This also helps to neatly organize all the code in a script file or the page <head> tag as well as contextually separate code from HTML blocks.

Parameters

readyCallback

: FusionCharts~readyCallback

[+]

Callback function executed when the FusionCharts framework is ready

args

: *

[+]

Argument to be passed to the callback function

Default:

FusionCharts

context

: function

[+]

To execute a function, passed using the fn parameter, in a different scope than the default FusionCharts scope, pass the appropriate class object here.

Default:

FusionCharts

Example

// Render a chart within a chart container `div` element.
FusionCharts.ready(function (FusionCharts) {
    var chart = new FusionCharts({
        type: "column2d",
        renderAt: "chart-container-div",
        dataSource: "my-chart-data.json",
        dataFormat: "jsonurl"
    });
    // Since we are in the `ready` block, the `chart-container-div`
    // element should be available by now.
    chart.render();
});

addEventListener

Used to listen to events triggered by a specific chart.

Parameters

type

: string or array

[+]

Type (name) of the event to listen to. To register the listener for multiple events in the same registration call, provide all event names as an array.

listener

: FusionCharts~eventListener

[+]

removeEventListener

Removes the event listener(s) bound to an event using the addEventListener() method.

Parameters

type

: string or array

[+]

Type (name) of the event whose listener(s) has to be removed

listener

: function

[+]

Listener function to remove

clone

Creates a copy of a chart instance, creating a new chart with identical construction properties of the chart being cloned. The cloned chart, assigned an auto-generated ID, is rendered in a container DOM element that is explicitly provided.

Parameters

overrides

: object

[+]

Object containing instructions for changes in the cloned chart. For example, passing pieChart.clone({type: 'column2d'}); will clone the pie chart, but set its chart-type as column2d. It accepts all the construction parameters of a new FusionCharts instance.

argsOnly

: boolean

[+]

Set to true, if a new FusionCharts object is not required. In that case, it causes the function to return a serializable object that can later be passed to create a new FusionCharts instance, and therefore, create a clone.

Default:

false

isActive

Denotes whether a chart is “active” or not after being rendered. This is primarily relevant for Flash variant of the charts since they tend to loose functionality when hidden or scrolled away as a measure to save system resources. For JavaScript charts, this returns false when a chart has not been rendered. As such, using the function hasRendered is more relevant.

chartType

Gets or sets the chart type of a FusionCharts instance. To get the current chart type, call this function without any parameters. To set a new chart type, pass the chart type as the first parameter to this function. When a new chart type is set, the chart is automatically re-rendered and the chartTypeChanged event is triggered.

Parameters

value

: string

[+]

New chart type to set

When changing the chart type, additional options can be passed to this method to update chart data and re-render the chart.

options

: {

dataSource

: string or object

[+]

New source of data while changing the chart type

dataFormat

: FusionCharts~dataFormats

[+]

Data format for the new data source. If this is not provided, then the existing/default data format is used.

Example

// Render a column chart and on click of a button toggle it from column to pie and vice versa.
FusionCharts.ready(function () {
    var chart = new FusionCharts({
        type: 'column2d',
        renderAt: 'chart-container',
        dataSource: 'weekly-sales.json',
        dataFormat: 'jsonurl'
    }).render();

    // Assign the functionality of toggling chart type when clicked on
    // a button (with an id toggle-chart-type).
    document.getElementById('toggle-chart-type').onclick = function () {
        if (chart.chartType() === 'column2d') {
            chart.chartType('pie2d');
        }
        else {
            chart.chartType('column2d');
        }
    };
