QT Graphing packages

QWT looks quite nice, maybe not as polished as KDChart, but definitly the nicest log/log graphs I've seen.

You have to use the still beta v1.5 if you using QT 4.0.

To build with MSVC-2005 you need to change the scope variable on the LIBS. There's no such scope as win32-msvc !!



Qwt (opensource)
KDChart (not free, but quite nice IIRC)
