## Main Features
2022-07-16 19:06:59 +08:00
- 2D Plotter widget class ([JKQTPlotter](http://jkriege2.github.io/JKQtPlotter/group__jkqtplotter.html)
2019-01-14 00:18:27 +08:00
- high-quality plotting
2022-04-23 02:19:25 +08:00
- no other dependencies than Qt >= 5.0 ([CImg](https://cimg.eu/) and [OpenCV ](https://opencv.org/ ) are optional dependencies)
2019-01-14 00:18:27 +08:00
- highly customizable axes/grids (linear/log, date/time, custom ticks ...)
2022-07-16 19:06:59 +08:00
- [JKQTMathText: ](http://jkriege2.github.io/JKQtPlotter/group__jkqtmathtext.html ) integrated LaTeX parser (pure C++, no dependencies) to render mathematical equations in axis labels, ticks, ...
2019-01-14 00:18:27 +08:00
- 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
- supports the Qt layout system for graphs and allows to symchronize several graphs with each other
- centralized data management in an internal datastore:
- 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, ...)
2019-05-30 04:47:26 +08:00
- C++ standard iterator interface
2019-06-02 00:20:36 +08:00
- statistics library (basic statistics, boxplots, histograms, kernel density estimates, regression analysis, polynomial fitting)
2019-01-14 00:18:27 +08:00
- large variety of graphs that can be added to a plot, e.g.:
- scatter-plots (also parametrized color/size/symbol by a third data-column)
- line graphs, step graphs, impulses
- filled curves
- barcharts (also stacked)
- extensive support for different styles of error indicators
- integrated mathematical function parser for function plots (with intelligent rendering algorithm)
- line/scatter graphs can also be based on C/C++ functions instead of data series (C++11 support!)
- statistical plots (e.g. boxplots)
- extensive library of image plots (inclusing different color-scale modes, RGBA-plots, overlays/masks)
- contour plots
- geometric forms/annotations
2020-09-21 19:15:57 +08:00
- can be easily extended by deriving a new graph from JKQTPPlotElement, JKQTPPlotAnnotationElement, JKQTPGeometricPlotElement, JKQTPGraph
2019-11-16 20:50:43 +08:00
- optional: OpenCV, CImg interfaces
2019-06-21 04:38:51 +08:00
- CMake-based build system
2019-01-14 00:18:27 +08:00
- extensive set of [Examples/Tutorials ](./examples/README.md )
2019-01-21 16:31:13 +08:00
- extensive doxygen-generated [Documentation ](http://jkriege2.github.io/JKQtPlotter/index.html )

2019-01-12 21:15:08 +08:00
## [Examples](./examples/)
There is a [large set of usage examples (with explanations for each) and tutorials ](./examples/ ) in the folder [`./examples/` ](./examples ).
2018-11-27 05:35:21 +08:00
All test-projects are Qt-projects that use qmake to build. You can load them into QtCreator easily.

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.
2019-06-22 20:21:32 +08:00
With [CMake ](https://cmake.org/ ) you can easily build JKQTPlotter and all its examples, by calling something like:
2019-06-21 04:44:42 +08:00
```
$ mkdir build; cd build
2019-06-22 20:21:32 +08:00
$ cmake .. -G "< cmake_generator > " "-DCMAKE_PREFIX_PATH=< path_to_your_qt_sources > "
$ cmake --build . --config "Debug"
2019-06-21 04:44:42 +08:00
```
