title: Gnuplot: transparency of data points when using palette
body: <p>Is there a way to plot transparent data points when using palette?</p>
  
  <p>I currently have the following code:</p>
  
  <pre><code>set style fill transparent solid 0.2 noborder
  set palette rgb 22,13,-22
  plot 'mydata.dat' u 1:2:3 ps 0.3 palette
  </code></pre>
  
  <p>My feeling is that transparency is overwritten by the arguments of the plot command.</p>
