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
