Solvedamcharts4 XYChart Line tooltips are overlapping (reopened #2)
✔️Accepted Answer
Found one of the issues regarding my comment above.
As per some of the demo charts, to put the tooltip text you should use the column template property:
https://www.amcharts.com/demos/simple-column-chart/
Problematic Line: series.columns.template.tooltipText = "{categoryX}: [bold]{valueY}[/]";
By modifying the template, the tooltip overlapping function that takes care of the position of the tooltips, loses track of where it it, and hence the issue.
The tooltip property to set the text should be:
series.tooltipText = "{categoryX}: [bold]{valueY}[/]";
And if needed, you can set the Y position of the tooltip by using:
series.tooltipY = am4core.percent(50);
That said, here is the chart with the wrong ToolTipText property being used:

And here is the chart with the correct ToolTipText property being used:

Other Answers:
I too am having overlapping tooltips in a Date/Value chart when using a panXY cursor.
In a XYChart, when y values are close to each other, tooltips are overlapping.
