Setting Data Source Using URL

FusionCharts lets you pass the complete JSON/XML chart data as a static string to the dataSource attribute. Alternatively, you can also save the chart data in a .json or .xml file and then pass the relative URL of this file as value to the dataSource attribute.

The only difference between the two methods is the value that is passed to the dataFormat attribute. For the first method, the dataFormat attribute takes json or xml as values, depending on the chart data. For the second method, the values will be jsonurl and xmlurl.

This article explains how you can set the chart data using the URL of the corresponding file.

Load data using JSON as URL

Let's build the same revenue chart which we built in the first example using JSON, and use a .json file as the data source.

FusionCharts will load here..

The data for this chart is represented in the table below:

Country No. of Oil Reserves
Venezuela 290
Saudi 260
Canada 180
Iran 140
Russia 115
UAE 100
US 30
China 30

The JSON representation for the above table looks as shown below:

    // Chart Configuration
    "chart": {
        "caption": "Countries With Most Oil Reserves [2017-18]",
        "subCaption": "In MMbbl = One Million barrels",
        "xAxisName": "Country",
        "yAxisName": "Reserves (MMbbl)",
        "numberSuffix": "K",
        "theme": "fusion",
    // Chart Data
    "data": [{
        "label": "Venezuela",
        "value": "290"
    }, {
        "label": "Saudi",
        "value": "260"
    }, {
        "label": "Canada",
        "value": "180"
    }, {
        "label": "Iran",
        "value": "140"
    }, {
        "label": "Russia",
        "value": "115"
    }, {
        "label": "UAE",
        "value": "100"
    }, {
        "label": "US",
        "value": "30"
    }, {
        "label": "China",
        "value": "30"

Copy this into a file, name it oilReserves.json, and store it in the same folder as your HTML page.

If you are using multi-lingual characters in your JSON, make sure that you save the JSON data with UTF-8 encoding.

The data structure needed to render the above chart is given below:

FusionCharts.ready(function() {
    var fusioncharts = new FusionCharts({
        type: 'column2d',
        renderAt: 'chart-container',
        width: '700',
        height: '400',
        dataFormat: 'jsonurl',
        dataSource: ''

When rendering your charts locally (without a web server, even if on the localhost), you will not be able to load data from XML or JSON files present on your hard-drive. This is due to security restrictions enforced by most modern browsers.

Load data using XML as URL

The XML representation for the above chart looks as shown below:

<chart caption='Countries With Most Oil Reserves [2017-18] ' subcaption='In MMbbl = One Million barrels ' xaxisname='Country ' yaxisname='Reserves (MMbbl) ' numberprefix='K ' theme='fusion '>
    <set label='Venezuela ' value='290 ' />
    <set label='Saudi ' value='260 ' />
    <set label='Canada ' value='180 ' />
    <set label='Iran ' value='140 ' />
    <set label='Russia ' value='115 ' />
    <set label='UAE ' value='100 ' />
    <set label='US ' value='30 ' />
    <set label='China ' value='30 ' />

Copy this into a file called oilReserves.xml and store it in the same folder as your HTML page.

If you are using multilingual characters in your XML, make sure you save the XML data with UTF-8 encoding.

To initialize the chart and instruct it using XML URL, use the following code:

FusionCharts.ready(function() {
    var myChart = new FusionCharts({
        "type": "column2d",
        "renderAt": "chart-container",
        "width": "700",
        "height": "400",
        "dataFormat": "xmlurl",
        "dataSource": ""
