Hi,

I’ve been following your instructions on linking multiple charts here: https://www.scichart.com/documentation/js/current/webframe.html#Tutorial%2009%20-%20Linking%20Multiple%20Charts.html

I have found that one chart in isolation runs at the full 60fps smoothness, but with each chart that is synchronised, it gets progressively slower until 5+ synced charts, at which point it becomes almost unusable. This is definitely an issue for our use-case, which will require a large number of synchronised charts.

This is currently using uniform heatmap charts only, I haven’t tried it with any others.

The issue occurs with and without data, i.e. a completely empty heatmap.

I also found that if I follow the instructions to the letter (i.e. a full two-directional link, with one chart pushing position changes to the other, and vice-versa), I get “Maximum depth exceeded” errors due to the infinite loop.

Am I doing something wrong? Are you able to recreate this issue?

Thanks
Joe

This “how do I” is primarily born from my question about multi-click annotations. This could also be it’s own topic so here goes:

How do I link annotations so that when the X2Y2 of line1 moves, X1Y1 of line 2 will move? Doing this in one direction I’ve been able to do. However, when I move X1Y1 of line2, line 1’s X2Y2 aren’t updated so they separate. Ideally, this should probably be event based. Is there a way to subscribe to the movement of the handles of a BaseAnnotation? My annotations are created dynamically so the linking method would need to be run time compatible.
