ValueError: Unrecognized marker style None

[davidglitvin]

If I run through the steps provided here for the "Cycle-by-cycle analysis of resting state data" tutorial on simulated data the plotting function bg[1].plot(xlim=(0, 10), figsize=(16, 3)) produces an error message stating "Unrecognized marker style None" and an incomplete figure (see attached).
I get the same error with my own data, or if I use the steps shown here. I also tried several generic fixes for matplotlib suggested on various boards. No luck so far. Any suggestions on how to deal with this? Any help would be much appreciated.

Hi, matplotlib update their API recently, see #144 for the fix. You could install from the main branch, rather than pypi. Or you could roll back you matplotlib version. I need to release the main branch on pypi soon - on my todo list for next week at the latest. Thanks!
