[Eeglablist] plotting channel/component activations

[Dorothy Bishop]

Fantastic. And I have found that if I modify it to specify 'color' on, then each channel is a different color!

i.e.
eegplot(EEG.icaact([1 2 3],:,:), 'srate', EEG.srate, 'events',  EEG.event,'color','on');

Many thanks.

Dear Dorothy,

a simple way to plot a subset of channels is to call eegplot from the  
command line.

eegplot(EEG.data([1 2 3],:,:), 'srate', EEG.srate, 'events', EEG.event);

For components

eegplot(EEG.icaact([1 2 3],:,:), 'srate', EEG.srate, 'events',  
EEG.event);
