All figures in subplot saved to animated gif file.

Hi,

I am attempting to save a sequence of figures created using the subplot() function to a .gif animation.

Currently, only one plot of the two presented in subplot is saved. The plot also does not have a title or xtick labels.

What modifications to my code do I need to make in order to save the subplot as it appears on my screen to the .gif file?

for ii = 1:5

      subplot(1,2,1);
      imagesc(rand(10))
      title(num2str(ii))
      daspect([1 1 1])

      subplot(1,2,2)
      imagesc(rand(10))
      title(num2str(ii))
      daspect([1 1 1])

      filename = 'saved_gif.gif';
      del = 0.1; % time between animation frames

      drawnow 
      frame = getframe(gca);
      im = frame2im(frame);
      [imind,cm] = rgb2ind(im,256);
      if ii == 1;
        imwrite(imind,cm,filename,'gif','Loopcount',inf,'DelayTime',del);
      else
        imwrite(imind,cm,filename,'gif','WriteMode','append','DelayTime',del);
      end

end

I think I have solved this myself. I will leave the answer here in case anyone else has a similar problem.

Ammended code:

fig_num = 1; % sets number of figure to be opened

for ii = 1:5

      figure(fig_num)

      subplot(1,2,1);
      imagesc(rand(10))
      title(num2str(ii))
      daspect([1 1 1])

      subplot(1,2,2)
      imagesc(rand(10))
      title(num2str(ii))
      daspect([1 1 1])

      filename = 'saved_gif.gif';
      del = 0.1; % time between animation frames

      drawnow 
      frame = getframe(fig_num);
      im = frame2im(frame);
      [imind,cm] = rgb2ind(im,256);
      if ii == 1;
        imwrite(imind,cm,filename,'gif','Loopcount',inf,'DelayTime',del);
      else
        imwrite(imind,cm,filename,'gif','WriteMode','append','DelayTime',del);
      end

end

Essentially, you need only to declare a figure number and call that number with getframe later in the script.

I hope this is helpful.
