Как изменить стиль курсора в сложенных LineSeries Amchart

Я знаю, как изменить их в ColumnSeries и PieSeries, с помощью:

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

или

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

Но я не могу заставить его работать в стековых LineSeries.

Вам необходимо установить это в шаблоне LineSeries 'segments. Это также требует включения взаимодействий на нем, так как они по умолчанию отключены: 

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

Демо: 

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

chart.data = [{
