How to format trackball tooltip text in ejChart?

Platform: ASP.NET Web Forms |
Control: Chart |
Published Date: February 12, 2015 |
Last Revised Date: July 2, 2019

By default, trackball displays the “x” value and “y” value of a point as tooltip text when you move the mouse over the Chart area. The “x” value in trackball tooltip text is formatted based on the LabelFormat property of the Horizontal axis used by the series and the “y” value displayed in trackball tooltip text is formatted based on the LabelFormat property of the Vertical axis used by the series.


    <ej:Chart ID="container" runat="server"> 
        <Crosshair Type="Trackball" Visible="true"></Crosshair>
        <PrimaryYAxis LabelFormat="${value} K"></PrimaryYAxis>


The following screenshot displays trackball with formatted “y” value.
