Hello,

I am using the following function to scroll to my epoched data for  
visual inspection: Epochs.plot(scalings = 'auto', n\_epochs = 5,  
n\_channels = 6, block = True). According to the help I should be able  
to scroll through the figure with the arrow buttons. However, when I  
press an arrow (or any button listed in the help list) nothing  
happens. I am running the code on a Mac Os Sierra. When I run the same  
code on a windows system I am able to scroll through the figure.

Is this a known problem and is there something that I can do?

Best,

Dirk van Moorselaar

hi Dirk,

how do you use mne? in a notebook? via spyder? in a terminal?

you may need to change the matplotlib backend:
