How to render text at the end of each line in an Angular Line Chart?

Description

This article shows how to render the text at the end of each line in the Angular Charts.

Solution

The data labels are text elements that provide additional information about individual data points. You can render a random text at the end of each line by using the text argument in the textRender event of the chart.

The textRender event is triggered for each data label in the Chart. You can change the text using the text argument if the point index is the same as the length of the data. Additionally, you can prevent the rendering of text by enabling the cancel argument in the textRender event.

Code Snippet

   public textRender(args: ITextRenderEventArgs): void {
       if(args.point.index == args.series.dataSource["length"] - 1)
           args.text = args.text + "th";
       else
           args.cancel = true;
   };
