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

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.

    <ej:Chart ID="container" runat="server">
