Main Features


A Documentation (auto-)generated with doxygen from the trunk source code can be found here:

There are also some subpage of general intetest:


There is a large set of usage examples (with explanations for each) and tutorials in the folder ./examples/. All test-projects are Qt-projects that use qmake to build. You can load them into QtCreator easily.


The Screenshots-page contains several screenshots, partly taken from the provided examples, but also from other software using this libarary (e.g. QuickFit 3.0)



Lates Release

JKQTPlotter contains two different build systems: A modern CMake-based build and an older (and deprecated!) QMake-based build (which works out of the box with Qt 5.x and QT 6.x). Both systems are explained in detail in

With CMake you can easily build JKQTPlotter and all its examples, by calling something like:

    $ mkdir build; cd build
    $ cmake .. -G "<cmake_generator>" "-DCMAKE_PREFIX_PATH=<path_to_your_qt_sources>"
    $ cmake --build . --config "Debug"
