How to plot two sets of differing variables under one figure?

I have two sets of ECG variables;

X and Y as one set, X1 and Y1 as one set.

How do I plot them both in one Figure, with the first set of data above the second set of data?

offset = abs(max(x)) * 1.1;
plot(x, y, 'b', x1, y1+offset, 'k')

thanks!

do you happen to know on how to do it separately but still within the same figure? for instance, set 1 in one box, set 2 in one box below set 1.

subplot(2,1,1); plot(x,y);
subplot(2,1,2); plot(x1,y1);
