@nerviozzo96,
The dynamic chart seems to be working fine at our end even for longer durations.
Can you kindly create a sample project reproducing the issue you are facing and share it with us over Google-Drive or Onedrive along with the sample data so that we can run the code locally at our end, look into the chart-options being used by you and help you out?
