Hello Frank,
Thank you for your video, I managed to reproduce the issue with our online demo.
However, I would like to note that I did not manage to determine the exact steps to reproduce the issue stably.
I have to move focus between different labels several times or move a mouse outside the chart in order to replicate this behavior.
In any case, we will investigate what can cause this issue and check for a suitable solution to resolve it.
If you have the exact steps which can be used to replicate the issue with our demo stably, please share it here.
It will be a great assistance to us.
If you move (pretty fast) from one tooltip to another and immediately leave the chart.
Hello Frank,
Thank you for the clarification. You are right, the issue is reproduced more stably if you move focus from one series to another quickly.
We will update the status of this ticket once we have any results.
Hi Oleg,
Any progress on this? When I run/debug it in VS this hardly happens, but on the production server it does:
