How to display the tooltip text in currency format in ASP.NET Web Forms Chart?

3 mins read

By default, the x and y value of a point is displayed in tooltip text, when you place the mouse over a Chart point. The LabelFormat property of horizontal axis is used to format the x value displayed in the tooltip and the LabelFormat property of vertical axis is used to format the y value displayed in the tooltip.

You can display tooltip in currency format by setting c (currency with two decimal places) as value to the LabelFormat property. Other possible values include c0, c1, c2, c3, etc.., for displaying the tooltip text in currency format.

ASP

    <ej:Chart ID="container" runat="server">
        <CommonSeriesOptions><Tooltip Visible="true"></Tooltip></CommonSeriesOptions>
        <PrimaryYAxis LabelFormat="c "></PrimaryYAxis>
        . . . . . .

    </ej:Chart>

A new version of Essential Studio for ASP.NET is available. Versions prior to the release of Essential Studio 2014, Volume 2 will now be referred to as a classic versions. The new ASP.NET suite is powered by Essential Studio for JavaScript providing client-side rendering of HTML 5-JavaScript controls, offering better performance, and better support for touch interactivity. The new version includes all the features of the old version, so migration is easy.
