Have a look at gnuplot: http://www.gnuplot.inf o/
It will be very helpful :-)

Yes, write the output from your program to a file, which you then read into gnuplot. Try the "plot" command:

gnuplot> plot "my_data_file.d at"

Yes, gnuplot is a stand-alone program, not a library or something, if that's what you mean.

I never used gnuplot under Windows, though ...
