JKQtPlotter

This is an extensive Qt5 Plotter framework (including a feature-richt plotter widget, a speed-optimized, but limited variant and a LaTeX equation renderer!), written fully in C/C++ and without external dependencies.

Main Features

• 2D Plotter widget class (JKQTPlotter)
  • high-quality plotting
  • no other dependencies than Qt >= 5.0
  • highly customizable axes/grids (linear/log, date/time, custom ticks ...)
  • integrated LaTeX parser (pure C++, no dependencies) to render mathematical equations in axis labels, ticks, ...
  • 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
  • supports the Qt layout system for graphs and allows to synchronize several graphs with each other
• centralized data management in an internal data store:
  • data organized by columns, can also represent image data (ropw-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)
  • export capabilities (e.g. to CSV, SYLK, ...)
  • C++ standard iterator interface
  • statistics library (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
  • bar charts (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 (including different color-scale modes, RGBA-plots, overlays/masks)
  • contour plots
  • geometric forms/annotations
  • can be easily extended by deriving a new graph from JKQTPPlotElement or JKQTPPlotObject
• optional: OpenCV, CImg interfaces
• CMake-based build system
• extensive set of Examples/Tutorials: https://jkriege2.github.io/JKQtPlotter/exampletutorialprojects.html
• extensive doxygen-generated Documentation: https://jkriege2.github.io/JKQtPlotter/index.html
