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

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
