title: Missing pgnuplot
body: <p>I'm trying to use gnuplot.py through cygwin, but it looks like I need to install pgnuplot (I get "/bin/sh: pgnuplot.exe: command not found" trying to run the demo.py file).</p>
  
  <p>The README provides an ftp link, but either its outdated or I don't think I understand how to use it. Could someone provide a way to easily install pgnuplot.exe? I've tried searching this, but couldn't decipher anything I found.</p>
