How to display the ToolTip text in currency format?

By default, X value and Y value of a point are displayed in ToolTip text on placing mouse over a chart point. The labelFormat property of the horizontal axis is used to format the X value displayed in the ToolTip and labelFormat property of the vertical axis is used to format the Y value displayed in the ToolTip.

ToolTip is displayed in currency format by setting c (currency with two decimal places) as the value to the labelFormat property. Other possible values include c0, c1, c2, c3, etc., for displaying ToolTip text in currency format.

JS

$("#container").ejChart({
    commonSeriesOptions: {
        tooltip: {
            visible: true,
        },
        . . . . . .
    },
    primaryYAxis: {
        labelFormat: 'c2’
        . . . . . .
    }
    . . . . . .
});
