Here is a script I botched together for converting GNUPlot files into PNGs. To see its output go to User:Mattrix/Scripts. If you'd like any help using it then please ask on the talk page. Here's some hints:

  • It requires gnuplot, LaTeX (including dvips and a few packages) and ImageMagick.
  • You might like to fiddle with the number after -density on the convert line.
