how to plot each profile with a distance from the other in a 2D plot ?

I want to plot something like this http://www.nature.com/nprot/journal/v9/n6/fig_tab/nprot.2014.090_F7.html or like this one http://file.scirp.org/Html/11-2200285/ff6819f9-5db9-4121-852d-a8d5c302a5a4.jpg I have a 2D matrix.

I tried to plot it like this but did not work

figure;
hold on
for i = 1:size(X,1)
 plot(X(i,:)+10)
end

any suggestion?
