# JKQtPlotter
This is an extensive library of function/data plotter classes for Qt (>= 4.7, tested with Qt up to 5.11).

This software is licensed under the term of the GNU Lesser General Public License 2.1

## Examples
This section assembles some simple examples of usage. 
You can find more (complex) examples for the classes in this repository in the subfolder "test". 
All test-projects are Qt-projects that use qmake to build. You can load them into QtCreator easily.
