Hello,
In my project I am using Non-Uniform Heatmap chart. My problem is that when I zoom in/out the performance is very poor and the FPS drops down a lot. First I thought the problem might be the size of heatmap I was rendering 10 x 3000, but then I tried to run example code from https://www.scichart.com/documentation/js/current/The-Non-Uniform-Heatmap-Chart-Type.html and it has the same performance issue with zValue of size 3×3
In my project I also use Uniform Heatmaps and these don’t have any visible performance issue, even for large amount of data.
I would be very grateful for your help in this matter

Hi Cezary,
Sorry for the late reply, for priority support we advise you to use https://support.scichart.com.
As for the injury, there is indeed a laggy zoom for the first few mousewheel ticks using the Non-Uniform HeatMap series. The size of the data can be much bigger, the bottleneck is the re-rendering of the textures working pixel-by-pixel as in the older WPF version, where it was not a problem. We are not sure yet about the fix or how long it will take, but we have added a ticket for it here: https://abtsoftware.myjetbrains.com/youtrack/agiles/68-17/69-1031
We could help in the meantime with other tips if you can give out more information about your use-case, maybe a UniformHeatMap, which does not have this problem, could suffice your needs.
Best,
