How to display the zooming scrollbar initially in Angular Charts?

Description

This article explains how to display the zooming scrollbar initially in Angular Charts.

Solution

The zooming scrollbar allows you to zoom in and zoom out of the chart. This scrollbar is displayed only when a zooming operation is performed on the chart.

You can display the zooming scrollbar during the initial render of the chart by setting the zoomFactor property to 0.3 in the primaryXAxis, enabling the enableScrollbar property to true in the zoomSettings property, and activating the isZoomed property in the load event of the chart.

Code Snippet:

The following code shows how to display the zooming scrollbar on the first load:

 zoomSettings = {
    enableSelectionZooming: true,
    mode: "X",
    enableScrollbar: true
  };
  
  primaryXAxis = {
      zoomFactor: 0.3
  };
  
  public load(args: ILoadedEventArgs): void {
       args.chart.zoomModule.isZoomed = true;
  };
