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: <>

It's a phenomenal little program, and among many other things makes publication-ready PDF plots.
