How to make spaces between graphs in a subplot

I am using subplot to plot a number of graphs (see program below). The graphs in the subplot are too close to each other and the title of the graph (on top of each graph) is overlapped with the x axis of the above graph. Is there a way to increase the row space between the graphs? Many thanks in advance.

for i = 1:nvar subplot(8,5,i); plot(cell2mat(nonstnlist(2:end,i))); set(gca,'XLim',[1,obs]); title(nonstnlist(1,i),'interpreter','non'); saveas(gca,'nonstnlist.fig'); end
