Example (JKQtPlotter): Examples & Tutorials

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

	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
	Plotting Geometric Objects

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

GUI Tools and Plot Layout

Screenshot	Description	Notes
	Layouting Several Plots	Combining plots in Qt Layouts linking plot axes copy data from a std::map int the datastore print plots/print preview
	Placing JKQtPlotter into a Qt User-Interface-XML-file (*.ui)	using Qt Form Designer parsed function plots (JKQTPxParsedFunctionLineGraph)
