title: How do I get gnuplot to read my time format and keep the times in order of the input file?
body: <p>I'm trying to get gnuplot to (a) read my input time format and (b) plot the time in order of the input file.  I'm trying to plot changes to a value over the past 24 hours starting at 18 UTC.</p>
  
  <p>It doesn't appear to like:</p>
  
  <pre><code>set xdata time
  
  set timefmt "%H%M"
  </code></pre>
  
  <p>It also likes to plot my xaxis values from 0000 UTC to 2300 UTC and drops leading zeros.  See below for input file.  I would like the newest data (1800UTC in this case) to be on the right side of my xaxis.  Thanks.</p>
  
  <pre><code>1900 23
  
  2000 22
  
  2100 22
  
  2200 22
  
  2300 22
  
  0000 22
  
  0100 22
  
  0200 21
  
  0300 21
  
  0400 21
  
  0500 21
  </code></pre>
  
  <p>and so on...</p>
