# 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
|
|
(LGPL 2.1) or above.

## 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.
