Lifecycle Events using Java

Events are signals that let you execute specific actions—such as sending data to the server, and so on—using JavaScript, in response to any interactions/updates for a chart. FusionCharts Suite XT includes advanced features that let you add more context to your chart and make data visualization simpler. These features include chart updates, and events.

The sample in this article lists the basic lifestyle events at the time of rendering the chart using FusionCharts JSP wrapper.

A chart is shown below:

FusionCharts will load here..
    "chart": {
        "caption": "Countries With Most Oil Reserves [2017-18]",
        "subCaption": "In MMbbl = One Million barrels",
        "xAxisName": "Country",
        "yAxisName": "Reserves (MMbbl)",
        "numberSuffix": "K",
        "theme": "fusion"
    "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"

        FusionCharts column_chart = new FusionCharts(

        column_chart.addEvent("dataLoaded", "onDataLoaded");


  1. Import and resolve the dependency fusioncharts.FusionCharts

  2. Include the necessary libraries and components using <script> tags. For example, fusioncharts.js, fusioncharts.theme.fusion.js.

  3. Within the <body>:

    • Include a <script> tag that contains the dataLoaded event.

    • Include a <div> tag with id same as the value of the renderAt attribute of the instance of FusionCharts (explained in the next step), within which the chart will be rendered.

    • Include a <% %> tag, where:

      • Declare a string jsonData and use it to assign the chart configuration as a JSON string.

      • Create a new instance named column_chart of the FusionCharts constructor, and pass the values of its arguments:

        • Set the chart type as column2d. Find the complete list of chart types with their respective alias here.

        • Set the id as column_chart.

        • Set the width and height of the chart in pixels. You can also provide them as percentages.

        • Set the renderAt as column2d.

        • Set the dataFormat as json.

        • Set the dataSource to jsonData which has been declared and defined above.

    • Include a <%= %> tag that contains column_chart.render().
