Why the hell would you want to do it with C++?

im looking for speed, the calculations that go into the graph are pretty long.

Just use Numpy like everyone else.

Use Python+Psyco. For graphics, use wxWidgets, I think I saw chart widgets somewhere. Or output something you can then feed GNUplot or something like that, I believe. Or do as I do, poor man's charts (AKA nigger charts):
Do it the Unix way: make the calculations in C, output it in a format suitable to feed to gnuplot, and pipe them together.

is there anyway to create like a virtual pipe/console in windows or dos? im already nigger piping (creating in.txt, system("xxx.exe < in.txt > out.txt"), then reading out.txt) another .exe to do some of the calculations
still working on it. im probably going to create a bitmap then display it. the piping part im not worried about yet since it still works well without it. (i would just integrate the .exe into my program since its open source but its library is sprawling shit) my next problem is screenscraping to detect certain images.
Also, get VC++ 6 or 7 (not dot net's 2002+). Most examples on the web can't be done without its MFC, and here is where free or open source alternatives fail. For example, if you want to even make an icon, you can't with just gcc. Your resource file has to be created somewhere else, even though cygwin has a resource compiler.
