title: gnuplot: Plotting X,Y coordinates and their label
body: <p>I have the following file (test.dat): </p>
  
  <pre><code>A   149 127
  B   19  157
  C   49  127
  D   149 147
  E   9   127
  F   49  12
  G   129 127
  </code></pre>
  
  <p>I would like gnuplot to plot these points with their label (a dot a position (149, 127), another dot at (19, 157), etc.). How can I do this?</p>
  
  <p>Thanks!</p>
