title: gnuplot postscript terminal not showing transparent symbols
body: <p>Hopefully, this is a stupid question, and easy to fix. When I run this simple gnuplot script:</p>
  
  <pre><code>#!/usr/bin/env gnuplot
  
  set term png
  set out "out.png"
  
  plot "&lt;jot -r -p 2 500 1 2" not w p pt 7 ps 4 lc rgb "#908DB6CD"
  
  set term post eps enhanced color
  set out "out.eps"
  
  replot
  
  exit
  </code></pre>
  
  <p>The png file looks like this:</p>
  
  <p><a href="https://i.stack.imgur.com/wKR2u.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/wKR2u.png" alt="png output"></a></p>
  
  <p>And the eps looks like this:</p>
  
  <p><a href="https://i.stack.imgur.com/bbhTg.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bbhTg.jpg" alt="eps output"></a></p>
  
  <p>The <code>pdfcairo</code> terminal also gives me transparency. Any clues on how to make the eps files show transparency?</p>
  
  <p>Many thanks in advance!</p>
