Charles, I just checked with the programmer and he's happy let wider information out about his plotting application, Graf. It's a proper Mac app, not a macport install. Sorry, no manual at present but the help file is useful: miocene.anu.edu.au/Graf <http://miocene.anu.edu.au/Graf>
It's a phenomenal little program, and among many other things makes publication-ready PDF plots.
