So call plot() 3 different times, specifying the axes you want the plot to show up in. Not sure what the difficulty is.
suplot(3, 1, 1);
plot(fft1, 'b-');
suplot(3, 1, 2);
plot(fft2, 'b-');
suplot(3, 1, 3);
plot(fft3, 'b-');

Hi, Thanks for the fast reply. Based on my understanding, the answers you given is for multiple subplot, the kind of plot I want is multiple fft on the same plot as the imagine I attached.

Try waterfall() or ribbon().
Or check out a bunch of possibilities in the gallery:
