title: Matlab: image plot caption overlapping the image
body: <p>I'm plotting several image subplots into one Matlab figure. (using <em>imshow()</em> and <em>subplot()</em>, respectively <em><a href="http://www.mathworks.com/matlabcentral/fileexchange/3696" rel="nofollow">subaxis()</a></em>)</p>
  
  <p>Using title() to describe the images consumes too much space in the figure.</p>
  
  <p>Therefore, I would like to write a caption overlapping part of the image (something like <em>legend()</em> for function plots), but I can't find a corresponding function for that.</p>
  
  <p>Is there some common way how to do that?</p>
  
  <p>Thanks in advance!</p>
