\section page_whatsnew_V2019_11 v2019.11: Major rework of the library
Starting in summer 2018, JKQTPlotter received some major workover. During this, it lost compatibility to the <a href="https://github.com/jkriege2/QuickFit3">QuickFit 3.0</a> code base. 

\subsection page_whatsnew_V2019_11_OVERVIEW v2019.11: Overview
Changes, compared to  \ref page_whatsnew_V2018_08 "v2018.08" include:

  <li> new: checked builds with continuous integration from AppVeyor: <a href="https://ci.appveyor.com/project/jkriege2/jkqtplotter/branch/master">https://ci.appveyor.com/project/jkriege2/jkqtplotter/branch/master</a> </li>
  <li> new/update: support for building with Microsoft Visual Studio (Win), MinGW (Win), GCC (Linux/MacOS) </li>
  <li> update: massively improved (doxygen-generated) <a href="http://jkriege2.github.io/JKQtPlotter/index.html">Online-Documentation (http://jkriege2.github.io/JKQtPlotter/index.html)</a> (automatically generated after each commit using ravis CI) </li>
  <li> update: refactoring of the library's directory structure </li>
  <li> update: refactoring/renaming of API, including the function anming scheme and class names </li>
  <li> changed: using static const variables instead of <code>#define</code> for fixed default values (e.g. JKQTPImageTools::LUTSIZE, JKQTPImageTools::PALETTE_ICON_WIDTH, JKQTPlotterDrawinTools::ABS_MIN_LINEWIDTH, JKQTMathText::ABS_MIN_LINEWIDTH ...)</li>
  <li> Updates to JKQTPlotter: 
    <ul>
	  <li> new: added JKQTPSingleColumnSymbolsGraph for single-column data, e.g. drawn as (random) scatter or bee-swarm or rug plots </li>
	  <li> new: stacked barcharts with JKQTPBarVerticalStackableGraph, JKQTPBarHorizontalStackableGraph </li>
	  <li> new: use/support of C++11 features (e.g. \c std::function<> and lambda functions in JKQTPXFunctionLineGraph / JKQTPYFunctionLineGraph )</li>
	  <li> new: \ref jkqtpinterfaceopencv  "optional OpenCV interface" </li>

	  <li> new: frames (plot viewport, key/legend ...) may be rounded off at the corners</li>
	  <li> new: diverse new styling options (default font name/size ...)</li>
	  <li> new: additionl options for styling coordinate axes</li>
      <li> new: Mix-In classes to unify plot styleing functions (setters/getters) in all graphs </li>
      <li> new: additional options for graph filling (color gradients, textures, ...) as provided by QBrush </li>
      <li> new: added a general feature to JKQTPPlotElement which allows to show a graph in a highlighted state (if supported by the derived graph class!) </li>
      <li> new: JKQTPXYParametrizedScatterGraph: added functors to transform column values into symbol type+size and line-width to give even more control </li>
      <li> new: user-interaction tool that shows coordinates of data points near the current mouse position (when mouse is dragged, while mouse button is pressed), see: jkqtpmdaToolTipForClosestDataPoint </li>
      <li> new: user-interaction tool that measures distances and angles when mouse is dragged, while mouse button is pressed), see: jkqtpmdaRuler </li>
      <li> new: advanced styling options for boxplots + example for the styling: \ref JKQTPlotterBoxplotStyling </li>
      <li> new: notched boxplots, see: \ref JKQTPlotterBoxplotStyling </li>
      <li> new: several new plot symbols, see: JKQTPGraphSymbols </li>
      <li> new: Statistics library with functions to calculate histograms, regression, kernel density estimates, ... see: \ref jkqtptools_math_statistics </li>
      <li> new: iterator interface and improved documentation for JKQTPDatastore </li>
      <li> new: violin plots (see \ref JKQTPlotterViolinplotGraphs ) </li>
      <li> changed: removed old selection-code and replaced by general highlighting feature </li>
      <li> changed: JKQTPStepHorizontalGraph has been renamed to JKQTPSpecialLineHorizontalGraph (vertical variants also) and have gained additional features (baseline for filling and drawing of symbols) </li>
      <li> changed: filled curve graphs (e.g. JKQTPSpecialLineHorizontalGraph) are now merely a specializedly initialized JKQTPSpecialLineHorizontalGraph </li>
      <li> removed: Removed datarange-feature </li>
      <li> update: \ref JKQTPLOTTER_USERINTERACTION "reworked user interactions API" </li>
      <li> update: \ref jkqtplotter_basegraphserrors "reworked error indicator base classes" </li>
      <li> update: improvements to contour plots (e.g. highlighting single contour levels, split into a class for simple C-arrays [JKQTPContourPlot] and one for image data in a JKQTPDatastore column [JKQTPColumnContourPlot]) + added example, see JKQTPColumnContourPlot and \ref JKQTPlotterContourPlot </li>
	  <li> fixed: colorbars at top were positioned over the plot label </li>
