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
To create drill-down charts, follow the steps given below:
Create the JSON/XML data for the parent chart. This is called the parent data source.
Append the data string or the data URL for the descendant charts within the parent data source. If you append a data string, the data for each descendant chart is embedded within the parent data source and is linked using unique data identifiers.
Once you implement these steps, the FusionCharts JavaScript class takes care of the rest. Let's see the steps in details.
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:
The JSON data to render the above chart is shown below:
