@fcbman,
The issue seems to be with x-value that you are passing, please refer this stackoverflow thread for more info. Can you try passing time-stamp instead of date and see if it works?
If the issue still persists. kindly share sample project along with sample data over Google-Drive or Onedrive so that we can run it locally at our end to debug and help you resolve the issue.
