QIPGraph is a set of C++ libraries and Excel interfaces to
interact with gnuplot, a fast
command line driven graphic software. Using QIPGraph, you can create complex
graphics with a few simple lines of C++ or in Excel.
Here is a simple example and the matching graph output by gnuplot using C++:
Plot plot(false,300,200); // get an instance of gnuplot
[-pi:pi] cos(x)" );
