A library to plot data (lines, maps...) in MFC projects
In this article, you will see a library called PGL that encapsulates plot capabilities in a MFC project for VC6 and VC7. It can easily plot data generated in a project without the need of any external software.
// PGLFont.cpp: implementation of the CPGLFont class.
