Addition of custom text like percentage in tooltip

Hello Team,
I am using Helical Insight 3.1 EE. I have created a chart which is showing percentage information. However I would like to append and show a Percentage symbol in front of the numeric values in tooltip. Is that possible?

Thank You

Hello Harika,

you can create the chart. Then in editor portion of the chart you can add the below JS function. This will append %.
In a similar way you can add other symbols / make other changes also as per your needs.

var viz_Options = c.get("viz_Options");
viz_Options.chartOptions.tooltip = {
format: {
value: function (value, ratio, id) {
return value + ' %';

After applying the above script the chart tool tip is appearing as below

Thank You
