JKQTPlotter - A Qt Plotting Library

This is an extensive C++ library for data visualization, plotting and charting for Qt (>= 5.0, tested with Qt up to 6.3). It is feature-rich but self-contained and only depends on the Qt framework.

This software is licensed under the term of the GNU Lesser General Public License 2.1 (LGPL 2.1) or above.

EXAMPLES-Page

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 tcmake to build. Some of them are also available with additional qmake build-files.

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

Building Using CMake

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 http://jkriege2.github.io/JKQtPlotter/page_buildinstructions.html.

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>" "-DCMAKE_INSTALL_PREFIX=<where_to_install>"
    $ cmake --build . --config "Debug"
    $ cmake --install . --config "Debug"

This will create CMake targets, which you can easily link against. For the main plotter library, the target's name is \c JKQTPlotter5::JKQTPlotter5 or \c JKQTPlotter6::JKQTPlotter6 depending on the Qt-Version you use. You can then simmply link against this via:

  find_package(JKQTPlotter6 REQUIRED)
  target_link_libraries(${PROJECT_NAME} JKQTPlotter6::JKQTPlotter6)

or on a Qt-version agnostic way via:

  find_package(JKQTPlotter${QT_VERSION_MAJOR} REQUIRED)
  target_link_libraries(${PROJECT_NAME} JKQTPlotter${QT_VERSION_MAJOR}::JKQTPlotter${QT_VERSION_MAJOR})

See https://jkriege2.github.io/JKQtPlotter/page_buildinstructions__c_m_a_k_e.html for details.

Usage via CMake's FetchConten-API

In addition to the method described above (i.e. build and install the library and then use it), you can also use JKQTPlotter via CMake's FetchContent-API.

For this method, you need to add these lines to your CMake project:

include(FetchContent) # once in the project to include the module
# ... now declare JKQTPlotter5/6
FetchContent_Declare(JKQTPlotter${QT_VERSION_MAJOR}
                     GIT_REPOSITORY https://github.com/jkriege2/JKQtPlotter.git
                     # GIT_TAG        v5.0.0)
# ... finally make JKQTPlotter5/6 available
FetchContent_MakeAvailable(JKQTPlotter${QT_VERSION_MAJOR})

These declare JKQTPlotter and make it available in your project. Afterwards you should be able to link against it, using

target_link_libraries(${PROJECT_NAME} JKQTPlotter${QT_VERSION_MAJOR}::JKQTPlotter${QT_VERSION_MAJOR})
