Main Features

Extensive Scientific 2D Plotting framework (JKQTPlotter / JKQTBasePlotter)
- high-quality plotting
- no other required dependencies than Qt5 or Qt6
- highly customizable axes/grids (linear/log, date/time, custom ticks ...)
- integrated LaTeX parser/renderer JKQTMathText for axis labels, ticks, notes ...
- 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 (styling system)
- 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 (row-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)
- built-in export capabilities for datatables (e.g. to CSV, SYLK, ...)
- C++ standard iterator interface
- Statistical Computations (basic statistics, boxplots, histograms, kernel density estimates, regression analysis, polynomial fitting)
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
- vector field plots
- financial charts (candlestick, OHLC, ...)
- geometric forms/annotations
- can be easily extended by deriving a new graph from JKQTPPlotElement or JKQTPGeometricPlotElement
OPTIONAL: Interfaces to external libraries
- OpenCV interface
- CImg interface
integrated LaTeX parser/renderer JKQTMathText :
- pure C++
- no dependencies in particular no installed LaTeX required
- can be used independently of JKQTPlotter
- for more details, see: JKQTMathText LaTeX-Renderer for Qt
an additional, simplified but speed-optimized plotter widget JKQTFastPlotter :
- is optimized for fast plotting, but is not as feature-rich as JKQTPlotter
- may be used independently of JKQTPlotter
- for more details, see: DEPRECATED: JKQTFastPlotter: Speed-Optimized Plotter class
CMake-based build system, see: Build using CMake
