Think you could help me "pop" the data so the segment in the window scrolls past a fixed time segment instead of continuously appending? I'm able to get past a couple of other obstacles but this one I don't have a clue on. It works fantastically other than this, same with several examples from pyqtgraph BUT I can't seem to get how to control the x axis to show a fixed segment of time....
If you are on linux, you can use picocom to read the serial data and pipe it into a file.
Hit ctrl-c if you want to stop logging. You can use tee to see and log the stream at the same time.
If you want to do it in python, you just have to take the above code and write the variable line to a file.
