How to Change the Tooltip Text Color in Angular Spline Charts?

This article explains how to change the tooltip text color based on the series color in Angular Spline Charts. You can dynamically change the tooltip text color in Syncfusion Angular Spline Charts based on the series color. This customization is achieved using the tooltipRender event of the chart.

The tooltipRender event is triggered just before the tooltip is displayed. Within the event handler, you can set the textStyle.color property of the tooltip to match the interior (fill color) of the corresponding series. This ensures the tooltip text color aligns visually with the series color.

The following code snippet shows how to implement this in Angular Spline Charts:

app.component.html

<ejs-chart (tooltipRender)='tooltipRender($event)'>
</ejs-chart>

app.component.ts

public tooltipRender(args: ITooltipRenderEventArgs): void {
   args.textStyle.color = args.series.interior;
};

The following screenshot illustrates the output of the above code snippet:
