Add Plus Sign To Column Chart Values (Tooltip)

[intapiuser]

You can accomplish it via JavaScript - you could make the value appear in that format within the data point tooltip of the column chart widget i.e. the box that appears when you hover over the columns.

widget.on("beforedatapointtooltip", function (w, arg) {
  
  if (arg.context.pointScope.y > 0) {
    arg.context.points[0].value = "+" + arg.context.points[0].value;
  }
});

This is a widget level script for the column chart widget you wanted this formatting to be applied to.
