title: Run Octave remotely and display locally via X11
body: <p>I'm currently implementing some machine learning algorithm by octave and run in the remote server. Once I type some drawing commands such like hist() it shows that</p>
  
  <pre><code>warning: X11 DISPLAY environment variable not set
  </code></pre>
  
  <p>Is it possible that I set the environment as my local X11 service. How to do it? Thanks.</p>
