Hi Timo,
Yes. Essential Chart supports InteractiveCursors - the cursor that follows the mouse automatically. Please refer the sample under [Installed Drive]:\Program Files\Syncfusion\Essential Studio\version number\windows\Chart.Windows\Samples\User Interaction\ChartInteractiveCursor
Note: This feature has been included only from Essential Chart version 3.3.0.0 onwards.
To set the stripline within the chart region use the following code snippet:
private ChartStripLine optimalZone = new ChartStripLine();
if((this.optimalZone.Start >= this.chartControl1.PrimaryXAxis.VisibleRange.Min )&& (this.optimalZone.End <= this.chartControl1.PrimaryXAxis.VisibleRange.Max))
this.optimalZone.Enabled = true;
else
this.optimalZone.Enabled = false;
Note: In case of zooming this coding should be included within the VisibleRangeChanged event of the chartControl. There is a KB article on this available at the following link:

I hope this helps you.
Thanks and Regards,
Geetha
