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

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

Screenshot	Description	Notes
