title: Converting a single col into mutiple rows (GNUPLOT file)
body: <p>I'm trying to make a gnuplot picture from a file, have a problem with the distribution of <code>'data.txt'</code> file. The actual distribution is :</p>
  
  <pre><code>1 4  x1 
  1 16 x2
  4 4  x3
  4 16 x4
  8 4  x5
  8 16 x6
  </code></pre>
  
  <p>The first line makes reference to the number of lines that i want, and the other colums make reference to the x and y axis.</p>
  
  <p>I'm trying two approximations to make the picture without success:</p>
  
  <ol>
  <li><p>Use some gnuplot function to sketch the picture using the actual distribution that my file have. I have not found this command.</p></li>
  <li><p>Make a bash script to convert the actual file into another with the correct distribution</p></li>
  </ol>
