How to format the tooltip text in JavaScript Chart?

2 mins read

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.
