an extensive Qt4/Qt5 Plotter framework (including a fast variant and a LaTeX equation renderer!), written fully in C/C++ and without external dependencies
Here is a list of all modules:
[detail level 123456]
 JKQTFastPlotter: Speed-Optimized Plotter classThis is an indepent (and fully self-contained) plotter class, which is optimized for drawing speed, rather than output quality. It lacks several of the advanced features of JKQTPlotter, but can be used in cases, where fast update of plots or real-time plotting is required
 JKQTMathText LaTeX-Renderer for QtThis group contains JKQTMathText, a self-contained LaTeX-renderer for Qt. It is used to renderer labels in JKQTPlotter, but can be used independently. The class does not depend on any library, except Qt. In particular it actually parses a LaTeX string and draws it in pure C++. It does NOT rely on an installed LaTeX for the rendering!

 Support Function library (e.g. for JKQTPlotter)This group contains several tool functions and datatypesthat are neccessary for JKQTPlotter, JKQTMathtext and the other major classes in this library, but may also be used separately. The functions and datatypes are sorted into several functionaly groups
