How to Apply Rounded Corners to Column Series points in Angular Chart?

This article explains how to apply rounded corners to column series points in an Angular Chart based on the point value. Using the chart’s pointRender event, you can dynamically set top corner radii for positive values and bottom corner radii for negative values.

Steps to Implement

1. Add a Column series to the Angular Chart.
2. Bind the pointRender event to the chart.
3. In the event handler:
   • Check the point’s y value.
   • Set series.cornerRadius accordingly:
     • For positive values, apply topLeft and topRight corner radius.
     • For negative values, apply bottomLeft and bottomRight corner radius.

Code Example

app.component.html

<ejs-chart (pointRender)="pointRender($event)">
    ........
</ejs-chart> 

app.component.ts

public pointRender(args): void {
   if (args.point.y > 0) {
     args.series.cornerRadius = {
       topLeft: 5,
       topRight: 5,
       bottomLeft: 0,
       bottomRight: 0,
     };
   } else {
     args.series.cornerRadius = {
       bottomLeft: 5,
       bottomRight: 5,
       topLeft: 0,
       topRight: 0,
     };
   }
 }
