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

## 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)
- export capabilities (e.g. to CSV, SYLK, ...)
- C++ standard iterator interface
- [statistics library](http://jkriege2.github.io/JKQtPlotter/group__jkqtcommon__statistics__and__math.html) (basic statistics, boxplots, histograms, kernel density estimates, regression analysis, polynomial fitting)
- large variety of [graphs](http://jkriege2.github.io/JKQtPlotter/group__jkqtplotter__graphsgroup.html) that can be added to a plot, e.g.:
- [scatter-plots](http://jkriege2.github.io/JKQtPlotter/group__jkqtplotter__linesymbolgraphs__param.html) (also parametrized color/size/symbol by a third data-column)
- [line graphs](http://jkriege2.github.io/JKQtPlotter/group__jkqtplotter__linesymbolgraphs__simple.html), [step graphs](http://jkriege2.github.io/JKQtPlotter/class_j_k_q_t_p_special_line_horizontal_graph.html), [impulses](http://jkriege2.github.io/JKQtPlotter/group__jkqtplotter__barssticks.html)
- [filled curves](http://jkriege2.github.io/JKQtPlotter/group__jkqtplotter__filledgraphs.html)
- [barcharts](http://jkriege2.github.io/JKQtPlotter/group__jkqtplotter__barssticks.html) (also stacked)
- extensive support for different [styles of error indicators](http://jkriege2.github.io/JKQtPlotter/group__jkqtplotter__basegraphserrors.html)
- [integrated mathematical function parser](http://jkriege2.github.io/JKQtPlotter/group__jkqtptools__math__parser.html) for [parsed function plots](http://jkriege2.github.io/JKQtPlotter/group__jkqtplotter__parsed_fgraphs.html) (with intelligent rendering algorithm)
- line/scatter graphs can also be [based on C/C++ functions](http://jkriege2.github.io/JKQtPlotter/group__jkqtplotter__functiongraphs.html) instead of data series (C++11 support!)
- [statistical plots)](http://jkriege2.github.io/JKQtPlotter/group__jkqtplotter__statgraphs.html) (e.g. boxplots, violinplots, ...)
- large variety of [image plots](http://jkriege2.github.io/JKQtPlotter/group__jkqtplotter__imagelots.html) (inclusing different color-scale modes, RGBA-plots, overlays/masks)
- [contour plots](http://jkriege2.github.io/JKQtPlotter/group__jkqtplotter__imagelots__contour.html)
- [geometric forms](http://jkriege2.github.io/JKQtPlotter/group__jkqtplotter__geoplots.html) / [annotations](http://jkriege2.github.io/JKQtPlotter/group__jkqtplotter__annotations.html)
- can be easily extended by deriving a new graph from [JKQTPPlotElement](http://jkriege2.github.io/JKQtPlotter/class_j_k_q_t_p_plot_element.html), [JKQTPPlotAnnotationElement](http://jkriege2.github.io/JKQtPlotter/class_j_k_q_t_p_plot_annotation_element.html), [JKQTPGeometricPlotElement](http://jkriege2.github.io/JKQtPlotter/class_j_k_q_t_p_geometric_plot_element.html), [JKQTPGraph](http://jkriege2.github.io/JKQtPlotter/class_j_k_q_t_p_graph.html)
- optional: [OpenCV interface](http://jkriege2.github.io/JKQtPlotter/group__jkqtpinterfaceopencv.html), [CImg interfaces](http://jkriege2.github.io/JKQtPlotter/group__jkqtpinterfacecimg.html)
- CMake-based build system
- extensive set of [Examples/Tutorials](./examples/README.md)
- extensive doxygen-generated [Documentation](http://jkriege2.github.io/JKQtPlotter/index.html)
## [Documentation](http://jkriege2.github.io/JKQtPlotter/index.html)
A Documentation (auto-)generated with [doxygen](http://www.doxygen.nl/) from the trunk source code can be found here:
**[http://jkriege2.github.io/JKQTPlotter/index.html](http://jkriege2.github.io/JKQtPlotter/index.html)**
There are also some subpage of general intetest:
- [TODO List](http://jkriege2.github.io/JKQtPlotter/page_todo.html)
- [Release Notes & Version Overview](http://jkriege2.github.io/JKQtPlotter/page_whatsnew.html)
## [Examples](./examples/)
There is a [large set of usage examples (with explanations for each) and tutorials](./examples/) in the folder [`./examples/`](./examples).
All test-projects are Qt-projects that use qmake to build. You can load them into QtCreator easily.
## [Screenshots](./screenshots/)
The [Screenshots-page](./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
[![Lates Release](https://img.shields.io/github/v/release/jkriege2/JKQtPlotter)](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>"
$ cmake --build . --config "Debug"
```
