Questions about refreshing components

Hi everyone,

I’m working on displaying 8 charts, each containing more than 1,000 double values (yes, that’s quite a lot of data). I’ve noticed that while the charts generate without issues during the initial page load, scrolling becomes choppy and laggy. I suspect this is because the charts are being recalculated every time there’s an event on the page.

My questions are:

  1. How does LVGL handle chart rendering? Are charts recalculated/redrawn on every page event?
  2. Is it possible to make a chart (or any object) “static”? I’d like to prevent unnecessary redrawing once the initial rendering is complete, especially during scroll events.
  3. Are there any recommended optimization strategies for handling multiple charts with large datasets?

Thanks in advance for any guidance!

Does anybody have an answer or some tips? Thanks
