Thanks @RyanAtSense,
Seems to be working though I’m not using on my highest res external monitor right now. But it was failing on with my current external monitor as well, and now works. I’m in the middle of a project to pull data from the web app, so I’m really focused on getting the highest resolution display of the daily waveform.
The size of the browser window influences the amount of data behind the waveform displays. Earlier, with the bug, I was limited to about 4288 data points. Now I’m seeing 7680 with a wider browser window.
