title: GNUPlot TimeFmt Issue
body: <p>So I'm pretty new to GnuPlot, and I can't seem to find out why I'm getting the error I am.</p>
  
  <p>Here's a sample of my data.txt file in the format <strong>(irrelevant id,name,time)</strong> :</p>
  
  <pre><code>3|Harpos|2010-08-28 02:44:55
  4|Harpos|2010-08-29 02:22:25
  5|Harpos|2010-08-29 02:09:19
  26|Harpos|2010-09-03 03:01:09
  </code></pre>
  
  <p>With the following configurations (the xrange is the ultimate bounds of my data):</p>
  
  <pre><code>set xdata time
  set timefmt x "%Y-%m-%d %H:%M:%S"
  set xrange ["2010-08-28 02:44:55":"2010-12-19 16:46:55"]
  set yrange [0:500]
  </code></pre>
  
  <p>What I'm trying to plot is this:</p>
  
  <pre><code>plot '/Users/kyleturner/Desktop/Harpos-placeholder.txt' using 0:3
  </code></pre>
  
  <p>As I'm trying to generate the # of occurrences (0 being the sequence # for each occurrence) in my data that happen at a specific time (over series of months).</p>
  
  <p><em>However, I keep getting the error:</em></p>
  
  <pre><code>"Bad format character"
  </code></pre>
  
  <p>Am I executing the "using" command incorrectly?  Can someone steer me in the right direction?  Once I get this down I'll be able to run some extensive sqlite queries to start generating some visuals.  </p>
  
  <p><strong>Thank you for your help, please let me know if I missed any details.</strong></p>
