How to disable the tooltip when the data point has zero value in Angular Charts?

Description

This article shows how to disable the tooltip when the data point has zero value in Angular Charts.

Solution

When you hover over a data point with your mouse, a tooltip appears to show information about that specific point. The tooltipRender event is triggered when the mouse hovers over the data point. If you want to disable the tooltip for a data point with a zero value, you can enable the cancel argument in the tooltipRender event of the chart.

Code Snippet

public tooltipRender(args): void {
   if (args.point.y === 0) {
     args.cancel = true; // Cancel the tooltip if y-value is 0
   }
 }
