title: Screen size in multiplot mode of Gnuplot
body: <p>I have 5 sub-plots, and only four of them are showing. The code snippets are as follows, since the original code is quite long; I am not able to increase the screen size to accomodate the 5th plot, and as a result, only the first four shows up:</p>
  
  <pre><code>set output 'test.png'
  set size 1.75,1.75
  set terminal png font "/Library/Fonts/Times New Roman Bold.ttf, 10" size 1000,700   
  set origin 0,0
  set multiplot
  
  #1st
  set size 0.5,0.5
  set origin 0,0.5
  ...
  #2nd
  set size 0.5,0.5
  set origin 0,0
  ...
  #3rd
  set size 0.5,0.5
  set origin 0.5,0
  ...
  #4th
  set size 0.5,0.5
  set origin 0.5,0.5
  ...
  #5th, and this one is not showing up
  set size 0.5,0.5
  set origin 1,0.5
  ...
  </code></pre>
  
  <p>Where am I going wrong?</p>
