title: How do I include greek letter in gnuplot?
body: <p>I'm using ubuntu 14.04 and gnuplot-x11, and found that for greek letter alpha,</p>
  
  <p>{/symbol a} will work, but that just shows me {/symbol a}, not greek letter alpha.</p>
  
  <p>I tried {\symbol a} or other options, but that does not work..</p>
