[Mne_analysis] problem about plotting raw date

[谭 淦升]

        External Email - Use Caution        

Dear MNE community,


I would like to plot de rawEEGLAB data (<RawEEGLAB  |  iVC_s01.set, n_channels x n_times : 32 x 105219 (210.4 sec), ~25.8 MB, data loaded> using raw_eeg.plot(). Then I get this: ValueError: The number of FixedLocator locations (20), usually from a call to set_ticks, does not match the number of ticklabels (1).



The complete error message is:

---> 72 raw_eeg.plot()

I am not sure where is the problem. Plotting raw data in another computer works just fine. Could you help me with this?

Thanks,
Gansheng
