that's the ideal manual solution for working with data and plots after testing.
However, having a real-time visual display (customizable) would be ideal. Even if the Serial Plotter's background could be set to transparent with option to show/hide the scales and labels, the user could move and re-size the Serial Plotter window over a datasheet plot, scope trace or any image for comparison and also use this feature to overlay on an image with new scaling and labels.
- An enhanced form of "visual" debugging while troubleshooting or calibrating
- User could showcase their code/project using the serial plotter as a customized display device
EDIT: Whoops ... my apologies ... thanks for the link. I'll definitely take a look into this!
