Hello, which version auf MNE-Python are you using? You stated 3.8, but this is most likely your version of Python, not MNE-Python. This problem actually should not occur with the latest stable release, 0.22, anymore. ---

@drammock, any idea what might cause this? ---

It’s a matplotlib error related to setting margins, probably in a call to subplots\_adjust(). Without a reproducible example is hard to say any more than that. Can you provide a code sample that reproduces the error, and tell us more about what you were doing when it happened (resizing the window perhaps?) ---

I am having the same error I am simply reading in EDF data and trying to plot it. Like : data = mne.io.read\_raw\_edf(raw\_path) data.plot() I am also using the %matplotlib qt, but I get the same error for the backend matplotlib.use(‘Qt5Agg’) and the TkAgg backend too. I think what happened is my mouse slipped and I resized the window so small, now I cant open anything. I tried using things like: plt = data.plot(duration = 30, start = 292, show = True) plt.subplots\_adjust(bottom=0) plt.subplots\_adjust(top=1) plt.subplots\_adjust(right=1) plt.subplots\_adjust(left=0) plt Nothing works. I hope you can help me @richard @drammock ---

Hello, a possible way to fix this is by resetting your MNE configuration. By default, MNE retains the size of your plotting window; if you delete the configuration file, the setting will be gone too, hopefully fixing your issue. You can find out where the config file is located by running: ```python import mne print(mne.get_config_path()) ``` If you then remove this file and restart Python / MNE-Python, all should be back to normal. ---
