Hello,

I am building up subplots in a loop like:

            h2(nn-1)=subplot(6,4,nn-1);
            mytitle=name;
            plot(x,y0,'k.',x,y,'r-',x,yp,'b-');

where nn is looping. Before I go to the next nn, I'd like to save off a full size version of the subplot to a .fig. Everytime I try something, the saved off works, but somehow the subplot doesn't build up anymore (there is only the last lower corner plot existing on the subplot). Somehow the save-off interfers with the main subplots.

What's the right way to build subplots while also saving off copies?

Thanks.

Before the loop do

fig = gcf;

Then change

h2(nn-1)=subplot(6,4,nn-1);

to

h2(nn-1)=subplot(6, 4, nn-1, 'Parent', fig);

I suggest you look at export_fig from the File Exchange. It can take an axes handle; it recreates the content of the axes in a figure and then saves the copy.
