koolplot is freeware open-source. It is a very simple-to-use software library for drawing graphs from C or C++ programs. http://www.codecutter.net/tools/koolplot/ I think this only works under Windows based GCC compiler. But not sure see web site.

Plplot (libplplot) a scientific plotting package. 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. It works under Linux GCC.
