How to change cursor style in Amchart's stacked LineSeries

Question

I know how to change them in ColumnSeries and PieSeries, via:

series.slices.template.cursorOverStyle = am4core.MouseCursorStyle.pointer

or

series.columns.template.cursorOverStyle = am4core.MouseCursorStyle.pointer

But I cannot make it work in stacked LineSeries.

Answer 1

You need to set this on the LineSeries' segments template. This also requires enabling interactions on it as they are disabled by default:

series.segments.template.interactionsEnabled = true;
series.segments.template.cursorOverStyle = am4core.MouseCursorStyle.pointer;

Demo:

var chart = am4core.create("chartdiv", am4charts.XYChart);

chart.data = [{
  "year": "1994",
  "cars": 1587,
  "motorcycles": 650,
