I have developed a Fortran-callable PostScript plotting
library called PSPLOT and have used it extensively to
create publication-quality graphics. It's written
in Fortran-77, supports the standard 35 PostScript fonts
and color, and is free for non-commercial use.
Disclaimers: It's not a pushbutton-type library, that is,
you can't create a graph with a single call.
However, it gives you almost total control
over your plots, which is why I developed it
in the first place.
It's 2-dimensional only.
No built-in screen support. It produces .ps files
only. You can view them with your PS viewer of choice.
You can get an overview of PSPLOT at http://www.nova.edu/ocean/
