hi, you can use : subplot(m,n,i)

where m is the number of lines, n is the number of columns and i the position of the current graph, but i do not know how to generate the legend in the last subplot :

Example , three lines and 2 columns

 r=randn(100,1); % Gaussian noise ~N(0,1)
 subplot(3,2,1)
 plot(r)
 subplot(322)
 plot(1.2*r);
 subplot(3,2,3)
 plot(1.4*r);
 subplot(3,2,4)
 plot(1.6*r);
 subplot(3,2,5)
 plot(1.6*r);
 subplot(3,2,6)
 plot(1.8*r);
