JKQtPlotter

This is an extensive library of function/data plotter classes for Qt (>= 4.7, tested with Qt up to 5.11).

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

Building

Building instructions can be found here:

• include necessary files into QMake project: ./lib/*.pri
• build a static library: ./staticlib/*.pro
• build a shared library (DLL): ./sharedlib/*.pro

Examples

This section assembles some simple examples of usage. You can find more (complex) examples for the classes in this repository in the subfolder "test". All test-projects are Qt-projects that use qmake to build. You can load them into QtCreator easily.

Different Plot Data Styles

Screenshot	Description	Notes
	Very Basic Example (Line Graph)	JKQTPxyLineGraph C++-style QVector arrays of data
	Line Graph with Live Data / Speed Test	JKQTPxyLineGraph external std::array<double,N> data, not owned by datastore live-data, measure plotting speed tipps to increas plotting speed
	Line Graph with Different Symbols and Line Styles	JKQTPxyLineGraph C++ vector of data setting line styles and symbol styles automatic graph coloring
	Step Line Plots in Different Styles	JKQTPstepHorizontalGraph (and JKQTPxyLineGraph) C++ vector of data different step modes, filled and line-only
	Simple Line/Symbol Graph With Errorbars	JKQTPxyLineErrorGraph C-style arrays of data
	Different Types of Error Indicators	JKQTPxyLineErrorGraph different styles of error indicators for x- and y-errors C++-style QVector for data styling error indicators moving key and formatting plotter grid
	Simple Bar Charts	JKQTPbarVerticalGraph C-style arrays of data
	Stacked Bar Charts	JKQTPbarVerticalStackableGraph, JKQTPbarHorizontalStackableGraph C++-style vectors of data
	Filled Curve Plots	JKQTPbarVerticalGraph setting/altering data in JKQTPdatstore directly transparent plots calculating histograms
	Impulse Plots	JKQTPimpulsesVerticalGraph and JKQTPimpulsesHorizontalGraph C++-style QVector as plot data
	Scatter Graph with Parametrized Symbols/Colors	JKQTPxyParametrizedScatterGraph C++-style QVector as plot data modify scatter/points/line-graph properties by data
	Draw an Artistic Image with a Parametrized Scatter Graph	JKQTPxyParametrizedScatterGraph C++-style QVector as plot data rectangular arrangement of scatters generative computer graphics
	Plotting Parametric Curves	JKQTPxyLineGraph and JKQTPxyParametrizedScatterGraph C++-style QVector as plot data parametric curve plotting
	Plotting Mathematical Functions as Line Graphs	JKQTPxFunctionLineGraph diretly plotting C/C++-functions
	Plotting Parsed Mathematical Functions as Line Graphs	JKQTPxParsedFunctionLineGraph plotting functions with the internal math equation parser/evaluator

Styling the Plot, Keys, Axes, ...

Screenshot	Description	Notes
	logarithmic axes	JKQTPxyLineGraph and JKQTPgeoText C++ vector of data logarithmic axes and styling plot line styles internal LaTeX parser add commenting text to a graph
	date/time axes	JKQTPxyLineGraph and JKQTPfilledVerticalRangeGraph C++ vector of data date/time axes plot min/max range graph internal LaTeX parser data from CSV files

Image data Plots

Screenshot	Description	Notes
	QImage as a Graph	JKQTPImage QImage drawn onto a plot with arbitrary scaling)
	Basic 1-channel Raw C Image Plot	JKQTPColumnMathImage image data copied from C-style row-major array into a single column of the internal datastore Describes several options of the image plotting classes (different ways of color coding, what to do with data above/below the limits etc.)
	Modifier-Feature of Image Plots	JKQTPColumnMathImage image data copied from C-style row-major array into a single column of the internal datastore Image is modified by a second image to display two data dimensions at the same time
	Basic 1-channel Raw C Image Plot without the internal datastore	JKQTPMathImage image data in a C-style row-major array, not using internal datastore
	1-channel OpenCV cv::Mat Image Plot	JKQTPColumnMathImage image data copied from OpenCV cv::Mat-structure into a single column of the internal datastore
	RGB OpenCV cv::Mat Image Plot	JKQTPColumnRGBMathImage image data copied from OpenCV cv::Mat-structure into three columns of the internal datastore
