title: Octave plotting with FLTK: Subplots getting smaller and smaller..?
body: <p>I'm using Octave 3.8.1.</p>
  
  <p>Consider the following code:</p>
  
  <pre><code>I=4;
  J=6;
  for j=1:J
      for i=1:I
          g=subplot(I,J,(i-1)*J+j);
          imagesc(rand(20,20));
      end
  end
  </code></pre>
  
  <p>This produces the following plot:
  <img src="https://i.stack.imgur.com/qrEYP.png" alt="strangely sized subplots"></p>
  
  <p>Why aren't the subplots equally sized?
  What do I need to do to get them equally sized?</p>
  
  <p>I'm using the default FLTK module for plotting.</p>
