[Eeglablist] EEGlab channel data - negative signals on positive y-axis

[JIMENEZ, MIKEL]

Hi,


I’m visualizing my EEG data using channel data (scroll) on EEGlab. However, I see that the negative signals are plotted on the negative y-axis, while I’d need them to be plotted on the positive y-axis.


Is there any way I could do that? I see that there is this similar question posted on Eeglablist, however I’m unable to find the optional parameter window to introduce ‘ydir’,-1 (e.g., On the EEGLAB graphic interface, you can usually enter 'ydir',-1 to obtain the desired effect in the optional parameter window).


Any help with this would be very much appreciated!

Thanks in advance,

Mikel
