title: superscript/subscript in the labels for gnuplot read from data file
body: <pre><code>1 1 A_{3}
  2 2 C_{2}
  3 3 ^{5}C_{1}
  </code></pre>
  
  <p>I have an input file like this to be plotted. The third column is for the labels on that point (in latex format). How do I get to appear these labels on the plot as they would appear after the latex compilation (as superscript/subscript/Greek alphabet etc.)</p>
