title: Octave-Gnuplot-AquaTerm error: set terminal aqua enhanced title "Figure 1"...unknown terminal type"
body: <p>I've installed Octave and gnuplot via Homebrew, and downloaded AquaTerm.dmg. 
  When I try to plot, I get the following message:</p>
  
  <p><code>octave:4&gt; plot(x,y)</code></p>
  
  <p><code>gnuplot&gt; set terminal aqua enhanced title "Figure 1"  font "*,6"</code></p>
  
  <pre><code>                  ^
       `line 0: unknown or ambiguous terminal type; type just 'set terminal' for a list`
  </code></pre>
  
  <p>In a bash terminal <code>set terminal</code>, <code>set Terminal</code>, <code>set term</code>, (and the same, followed by "aqua" too) etc gives nothing.
  I've tried plotting again from octave having the "AquaTerm" already open, but nothing. I've tried plotting directly from gnuplot but same problem.. How can I do this "set terminal aqua"?</p>
  
  <p>Gnuplot starting message says "<code>Terminal type set to 'x11'</code>" but no idea how to change it, the previous commands didn't work neither.</p>
  
  <p>Since AquaTerm wasn't installed from Homebrew maybe octave/gnupot can't find it... but no idea. 
  Any guess? Thanks!</p>
