Adding Drill Down using React

With FusionCharts, you can create unlimited levels of drill-down with a single data source. The parent chart contains all data — for the parent chart as well as all descendant (child, grandchild) charts. The links to all the descendant charts are defined in the parent chart.

You can drill-down to descendant charts by simply clicking the data plot items on the parent chart. A descendant chart can either replace the parent chart with an option to drill-up or it can open in a new window or frame.

Features of the FusionCharts JavaScript Class

  • Automatically creates and shows a detailed descendant chart when you click on the corresponding data plot item linked in the parent chart

  • Clones all chart configuration settings from the parent chart to create the descendant charts

  • Accepts specific properties for descendant charts when you configure them using the configureLink() function.

  • Uses events to notify your code when a link is invoked, a link item is opened, or a link item is closed

  • Supports drill-down to an unlimited number of levels

Create drill-down charts

As an example, we will consider a simple scenario of a parent chart with a single level of drill-down.

The parent chart is a column 2D chart showing yearly sales of the top three juice flavors, over the last one year. When you click on the data plot for a particular flavor, it drills down to show a pie 2D chart showing the quarterly sales figures for that flavor.

The above chart, when rendered, looks like the following:

Click here to edit the above chart.

The above chart has been rendered using the following steps:

  1. Included the necessary libraries and components using import. For example, react-fusioncharts, fusioncharts, etc.

  2. Stored the chart configuration in a JSON object. In the JSON object:

    • The chart type has been set to column2d for the first chart. For Column 2D chart, the alias is column2d. Once the data plots in the Column charts are clicked, the rendered chart is a Pie 2D chart (alias name: pie2d). Find the complete list of chart types with their respective alias here.
    • The width and height of the chart has been set in pixels.
    • The dataFormat is set as JSON.
  3. A DOM element has been created and the react-fusioncharts component is passed directly to the ReactDOM.render() method.
