# 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](https://qt.io).

## Main Features
|
|
- 2D Plotter widget class [JKQTPlotter](http://jkriege2.github.io/JKQtPlotter/group__jkqtplotter.html):
|
|
- high-quality plotting
|
|
- no other dependencies than Qt >= 5.0 ([CImg](https://cimg.eu/) and [OpenCV](https://opencv.org/) are optional dependencies)
|
|
- highly customizable axes/grids (linear/log, date/time, custom ticks ...)
|
|
- [JKQTMathText:](http://jkriege2.github.io/JKQtPlotter/group__jkqtmathtext.html) integrated LaTeX parser (pure C++, no dependencies) to render mathematical equations in axis labels, ticks, ...
|
|
- extensive user-interactions pre-programmed (several zooming modes, selecting regions, custom context menus, switch graph visibility, ...)
|
|
- full print and export (PDF,PNG,...) support with preview and parametrization out-the-box
|
|
- [highly customizable look and feel](http://jkriege2.github.io/JKQtPlotter/group__jkqtpplotter__styling.html)
|
|
- supports the Qt layout system for graphs and allows to symchronize several graphs with each other
|
|
- [centralized data management](http://jkriege2.github.io/JKQtPlotter/group__jkqtpdatastorage.html) in an internal datastore [JKQTPDatastore](http://jkriege2.github.io/JKQtPlotter/class_j_k_q_t_p_datastore.html):
|
|
- data organized by columns, can also represent image data (ropw-major)
|
|
- allows to reuse a column in several graphs
|
|
- access via Qt's model view framework
|
|
- external or internal datasets
|
|
- complete with GUI (table view)
|
|

|
|
- C++ standard iterator interface
|
|
- [statistics library](https://jkriege2.github.io/JKQtPlotter/group__jkqtptools__math__statistics.html) (basic statistics, boxplots, histograms, kernel density estimates, regression analysis, polynomial fitting)
|
|

There is a [large set of usage examples (with explanations for each) and tutorials](https://jkriege2.github.io/JKQtPlotter/example_tutorial_projects.html) in the folder [`./examples/`](./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](./screenshots/) contains several screenshots, partly taken from the provided examples, but also from other software using this libarary (e.g. [QuickFit 3.0](https://github.com/jkriege2/QuickFit3))

|
|
## Building Using CMake
|
|
|
|
[](https://github.com/jkriege2/JKQtPlotter/releases)
|
|
|
|
JKQTPlotter contains two different build systems: A modern [CMake](https://cmake.org/)-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](https://cmake.org/) 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${QT_VERSION_MAJOR})
|
|
```
|
|
See https://jkriege2.github.io/JKQtPlotter/page_buildinstructions__c_m_a_k_e.html for details.
|
|
|
|
## Usage via CMake's FetchConten-API
|
|
|
|
In addition to the method described above (i.e. build and install the library and then use it), you can also use JKQTPlotter via CMake's [FetchContent-API](https://cmake.org/cmake/help/latest/module/FetchContent.html).
|
|
|
|
For this method, you need to add these lines to your CMake project:
|
|
```
|
|
include(FetchContent) # once in the project to include the module
|
|
# ... now declare JKQTPlotter5/6
|
|
FetchContent_Declare(JKQTPlotter${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})
|
|
```
