External Email - Use Caution
Hello MNE users,
I am seeking help with figuring out how to prevent the figures from
displaying when using this function:
https://martinos.org/mne/stable/generated/mne.viz.plot_topomap.html#mne.viz.plot_topomap
In using this mne.viz.plot_topomap, my aim is to save out the figure as a
.png without it opening in a new window and without me having to manually
close the figure. Here is how I am using the function:
fig_a=plt.figure()
mne.viz.plot_topomap(data_array,
pos=mne.channels.read_montage('biosemi64').pos[:64,:2])
plt.close(fig_a)
fig_a.savefig('/home/dcellier/data_array_topoplot.png')
The result is that the topomap figure is popping up and pauses the script
until I close it. This is problematic because this code is nested in a for
loop and will be called upon >100 times. It does successfully save the
topomap in the intended directory.
What I've tried, to no avail:
import matplotlib.pyplot as plt
plt.ioff() #turning interactive plotter off
print(matplotlib.is_interactive()) #returns False
matplotlib.use('Agg')
as well as plt.close(). I also tried assigning the output of
mne.viz.plot_topomap() to a variable, but it doesn't work to suppress the
figure.
Thank you in advance for any assistance!!
Best wishes,
Dillan
