Hello,

I'm using MNE with the IDLE IDE for Python 3.7 and am having problems
making my raw plot interactive. I was able to overcome this problem when
doing everything in Jupyter.

My input file is edf and not fif. The relevant commands from within my
script are as follows:

directory='/Users/fishbacp/Desktop/my_file.edf'
raw = mn.io.read_raw_edf(directory, preload=True)
raw.plot()

The graph appears, but the scrolling features don't function, nor the HELP
button.

Thanks for any assistance.

Do you have matplotlib interactive mode enabled? For example with
`plt.ion()` in plain Python, or `%matplotlib qt` in IPython?

Hi Eric,

Thanks for the suggestion. I tried using plt.ion() since I'm working in
plain Python, but that didn't fix the issue.

I'm doing everything on a Mac with Catalina 10.15.4. Might that have
anything to do with the problem.

Your second suggestion for IPython is what always worked for me in Jupyter.

Thanks again.

Does `mne sys_info` under "matplotlib" say that you are using the MacOSX
backend for matplotlib? If you do `matplotlib.use('Qt5Agg')` at the top of
your script does it work? The MacOSX backend sometimes has
issues, generally the Qt5Agg backend tends to work better.

Unfortunately, neither backend solves the problem.
