Scientific plotting library (fortran bindings)
PLplot is relatively small, portable, freely distributable, and is rich enough to satisfy most users. It has a wide range of plot types including line (linear, log), contour, 3D, fill, and almost 1000 characters (including Greek and mathematical) in its extended font set. The package is designed to make it easy to quickly get graphical output; only a handful of function calls is typically required. For more advanced use, virtually all aspects of plotting are configurable. . This package contains the Fortran 95 bindings for PLplot. Note: the Fortran 77 bindings have been deprecated upstream for some time and have now been dropped from the Debian packages.
