How to format the tooltip text in JavaScript Chart?
By default, the x and y value of a point is displayed as the tooltip in JavaScript Chart when you place the mouse over a Chart point. The labelFormat property of horizontal axis used by the series is used to format the x value displayed in tooltip and the labelFormat property of vertical axis used by the series is used to format the y value of text displayed in tooltip.
JS
$("#container").ejChart({ commonSeriesOptions: { tooltip: { visible: true, } }, primaryYAxis: { labelFormat: '${value} K' } });
The following screenshot displays the Chart with formatted y value of the point in tooltip text.
