Hi everyone,

I was wondering if it is possible to save a figure without displaying it (because I do not have a graphic card on my working computer).

Thanks a lot !

Try this:

figure( h );
plot(....,'Visible',off);
hgsave(h,'filename');
close h;

If I remember correctly, when you open it elsewhere, you will have to set visibility to 'on' again.

h=open('filename.fig');
set(h,'visible','on')

Thanks a lot "vortse_a", I'm replying to your answer because I have the same problem.    I have tried your suggestion, and it works.

Only, I would like that the figure, the .fig file, when double clicked, just simply be displayed in MATLAB without the need of issuing any command to activate visibility.  As it works now, the .fig file, when doble clicked, produces no display.

So the final question, at least from my side, is:  is it possible, in a batch program, to save a few figures without interacting with the screen at all?  And the saved figures should be .fig (with graphics files, all is ok, for example .png works fine).

Best regards

one of the many solutions

     tmpl='afig';     % <- the file name template...
for  i=1:3
     fnam=sprintf('%s_%2.2d',tmpl,i);     % <- current file name...
     clf;
     plot(rand(10,1));
     saveas(gcf,fnam,'fig');
end
     dir('afig*.*');
%    afig_01.fig  afig_02.fig  afig_03.fig

thanks us, probably I did not explain correctly what I'm looking for.
I would like to save without any plot activity on the screen!
Imagine the following scenario... a long MATLAB application, running "in background", needing now and then to save a few plots.  The user on the PC is doing something else ... every plot command produces a popup window that interrupts any other activity, jumping in the foreground.  
Your example, in my understanding, does work, and is familiar to me, but it opens a "figure" window 3 times.   What I need is something like a "silent" saving of figure.
Best regards & thank you

That could happen if the stored figure happens to have 'Visible' set to 
'off'. If so, then you cannot display it without using at least one 
command at some point in time.
