title: How to start at x = 0 with given xrange in gnuplot?
body: <p>in gnuplot, is it possible to start the graph at x = 0 in given x range?</p>
  
  <p>Let say that I have this code:</p>
  
  <pre><code>set xrange [100:500]
  plot "input.txt" using 2:1:(1.0) notitle with lines lw 1
  </code></pre>
  
  <p>Consequently, the graph will start at x = 100 and end at x = 500. 
  I want the graph to start at x = 0 and end at x = 400 with the given range [100:500].
  How can I do this?</p>
  
  <p>Thanks!</p>
