Overlapping should be possible by using the hold command, enabling you to create more than one plot in the same figure.
hold on
plot1
plot2
and so on
hold off
Framing can be done by specifying the values of your data that you want to process, for example:
EEG = [ 0.4 ; 0.5 ; 0.6 ; 0.7 ; 0.6 ; 0.5 ; 0.4 ]
EEG_peak = EEG(3:5,1)
EEG_peak = [0.6 ; 0.7 ; 0.6]
And there you have the data just around the peak in this very simple example. The syntax is: data(rows,columns) so the previous example is rows 3 through 5 in column 1.
