\mainpage JKQTPlotter - A Qt Plotting Library
This is an extensive library of function/data plotter classes for Qt (>= 4.7, tested with Qt up to 5.11).

\section jkqtp_main_features Main Features
- Extensive Scientific 2D Plotting framework (JKQTPlotter/JKQTBasePlotter)
  - high-quality plotting
  - no other dependencies than Qt >=4.7 (compatible with Qt 5.xx)
  - 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
  - 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 (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)
  - built-in export capabilities for datatables (e.g. to CSV, SYLK, ...)
- 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 
  - geometric forms/annotations, see: \ref jkqtplotter_geoplots 
  - can be easily extended by deriving a new graph from JKQTPPlotElement or JKQTPPlotObject
- optional: OpenCV interface, see: \ref jkqtpopencvinterface 
- integrated LaTeX parser/renderer JKQTMathText:
  - pure C++ 
  - no dependencies in particular no installed LaTeX required
  - can be used independently of JKQTPlotter
  - see: \ref jkqtmathtext
- a second plotter widget JKQTFastPlotter:
  - is optimized for fast plotting, but is not as feature-rich as JKQTPlotter
  - may be used independently of JKQTPlotter
  - \see jkqtfastplotter
- extensive set of Examples and Tutorials, see: \ref exampleTutorialProjects
- extensive doxygen-generated <a href="http://jkriege2.github.io/JKQTPlotter/index.html">Online-Documentation (http://jkriege2.github.io/JKQTPlotter/index.html)</a>
- source code hosted&developed on GitHub <a href="https://github.com/jkriege2/JKQTPlotter">https://github.com/jkriege2/JKQTPlotter</a> (including continuous integration builds: <a href="https://ci.appveyor.com/project/jkriege2/jkqtplotter/branch/master">https://ci.appveyor.com/project/jkriege2/jkqtplotter/branch/master</a>)
