[Eeglablist] Sorry for my bad English!

[Ettore Coppola]

Sorry for my bad English and for my stupid problem!
I am a newbe in EEGLAB; I imported data from Matlab. When I try to plot the raw EEG data, in Plot-Channel Spectra and Maps I got a good map with the 8 colored channels (the first attacched image);
on the contrary, in Plot- Channel Data (scroll) I dont’see anything (the second attacched image)!!!
Have you some suggestion to undertand how I made my mistake?
Thank you very much!
Ettore
