<li>FIXED issue described in <a href="https://github.com/jkriege2/JKQtPlotter/pull/62">#62: Fix custom labels draw, because giving exactly two label-strings did not display all of them</a>, thanks to <a href="https://github.com/FalsinSoft">user:FalsinSoft</a></li>
<li>FIXED issue <a href="https://github.com/jkriege2/JKQtPlotter/pull/70">#70: Typo in jkqtplotter/CMakeLists.txt</a>, thanks to <a href="https://github.com/tedlinlab">user:tedlinlab</a></li>
<li>FIXED issue <a href="https://github.com/jkriege2/JKQtPlotter/pull/80">#80: Bug with multiple inheritance with Q_GDAGET with CLANG</a>, thanks to <a href="https://github.com/igormironchik">user:igormironchik</a>, caused by <a href="https://bugreports.qt.io/browse/QTBUG-104874">QTBUG-104874</a></li>
<li>NEW: JKQTPFilledCurveXGraph and JKQTPFilledCurveYGraph can now plot wiggle plots with different fill styles above and below the baseline (feature request <a href="https://github.com/jkriege2/JKQtPlotter/issues/68">#68 Wiggle Plots</a> from <a href="https://github.com/xichaoqiang">user:xichaoqiang</a> </li>
<li>NEW/BREAKING CHANGE: data tooltip can now also be shown when "just" moving the mouse (so far this was only possible when dragging the mouse with a button pressed). This also removes JKQtPlotter::getActMouseLeftAsToolTip() and adds JKQtPlotter::getActMouseMoveToolTip() instead! Also the default toolbars and context menus changed!</li>
<li>NEW/BREAKING CHANGE: changed JKQTPColorDerivationMode into a struct, which extends its capabilities above the previously available few enum-items</li>
<li>NEW: added debug-feature to show boxes around text in the plot</li>
<li>BREAKING: Print-Support can now be switched off with a CMAKE-option JKQtPlotter_BUILD_FORCE_NO_PRINTER_SUPPORT=ON. This also switches off PDF and SVG export, partly solves issue <a href="https://github.com/jkriege2/JKQtPlotter/issues/81">#81</a>, many thanks to <a href="https://github.com/sufuk">user:sufuk</a> for contributing part of the code and supplying the idea! </li>
<li>NEW: improved plotting speed for line-graphs by a compression algorithm (see JKQTPGraphLinesCompressionMixin) that removes overlaying lines (e.g. in JKQTPXYLineGraph)</li>
<li>NEW: improved plotting speed for line-graphs by a clipping algorithm (applies to JKQTPXYLineGraph, JKQTPGraphErrorStyleMixin, JKQTPSpecialLineHorizontalGraph, JKQTPSpecialLineVerticalGraph and others)</li>
<li>NEW: improved plotting speed for scatter-graphs by not calling draw functions for symbols outside the plot window (e.g. in JKQTPXYLineGraph)</li>
<li>FIXED: JKQTMathText added a little whitespace before and after the LaTeX-string. This was removed as it disturbed the layout of text in plots</li>
<li>FIXED: height-calculation of frac-like instructions: before the ascent and descent were equal, even if the numerator and denominator have different heights</li>
<li>FIXED: strikeoutPos was not correctly calculated in sub-/superscript node</li>
<li>FIXED/IMPROVED: JKQTMathText renders several LaTeX strings better (simple braces in math mode, \c +-*... as symbols with proper sizes in math mode, added some missing instruction aliases, improved size of \\vec and \\hat, corrrected fonts usage for \\mathrm</li>
<li>FIXED: \c \\sum and \c \\prod used the wrong symbol in XITS-mode</li>
<li>MODIFIED: brace node now calculates the extension of the child height above or below the strikeoutPos, in order to center braces around the strikeoutPos</li>
<li>IMPROVED: tokenizing and parsing of text in text-mode: now a lot of accents with commands like \c \\\"a, \c \\'e and variants (e.g. \c {\\\"a}, \c \\\"{a}, ...) are supported now</li>
<li>IMPROVED/BREAKING: refactored symbol node JKQTMathTextSymbolNode and changed font-lookup!</li>
<li>IMPROVED/NEW/BREAKING: refactored whitespace-processing node JKQTMathTextWhitespaceNode, now all major LaTeX whitespace commands are supported properly</li>
<li>IMPROVED/NEW/BREAKING: refactored LaTeX parser in JKQTMathText</li>
<li>REMOVED/BREAKING: \c \\v[a-zA-Z] and shorthand for \c \\vec{a-zA-Z} was removed, implementation of \c \\bbR,\c \\bbC,... changed</li>
<li>MODIFIED/BREAKING: new options interface for JKQTMathText::parse()</li>
<li>IMPROVED/REWORKED rendering of blackboard font: now several different rendering modes can be selected using JKQTMathText::setFontBlackboradMode()</li>
<li>BREAKING/CLEANUP: cleanup: Removed Parameter prevNodeSize from JKQTMathTextNode::draw() and JKQTMathTextNode::getSize()/JKQTMathTextNode::getSizeInternal(), since it is only really necessary for JKQTMathTextSubscriptNode and JKQTMathTextSuperscriptNode</li>
<li>BREAKING/CLEANUP: using JKQTMathTextNodeSize for all size-calculation functions and got rid of all functions that take the output parameters with call-by-reference, additional information can be outut by local size-classes that derive from JKQTMathTextNodeSize, see e.g. JKQTMathTextSymbolNode::NodeSize and JKQTMathTextSymbolNode::getSymbolSize()</li>
<li>NEW: JKQTMathTextVerticalListNode allows to typeset a vertical list of lines</li>
<li>NEW: JKQTMathText::parse() by default allows linebreaks in the LaTeX string to be parsed. This can be switched off by a parameter</li>
<li>NEW: added functions to set the font-size in pixels (as alternative to the existing functions that set them in points), implements request <a href="https://github.com/jkriege2/JKQtPlotter/issues/76">#76</a> from <a href="https://github.com/igormironchik">user:igormironchik</a> </li>
<li>NEW: additional method JKQTMathtext::getSizeDetail() that returns all size-properties as a convenient struct, also added matching varinat JKQTMathTextNode::getSize() </li>
<li>NEW: additional method JKQTMathtext::drawIntoPixmap(), JKQTMathtext::drawIntoPicture(), JKQTMathtext::drawIntoImage() which returns a QPixmap, QPicture and QImage respectively that contains the render result of the currently parsed markup</li>
<li>NEW: array/tabular-environments have limited support for formatting string like \c l|r|c and for \c \\hline , \c \\hdashline , \c \\toprule , \c \\midrule , \c \\bottomrule</li>
<li>NEW: reworked code structure: broke up large, single CPP-files into several smaller files!</li>
<li>NEW: reworked node class tree: inserted base-class nodes for single-child, dual-child!</li>
<li>NEW: improved frac-rendering: font-scaling takes nesting-level into account, overall-rendering, sizes, if a brace surrounds a frac, the heights are equal above and below to center the brace , ...</li>
<li>NEW: \c \\limits and \c \\nolimits works as in LaTeX now (before it was simply removed and the functionality implemented for a fixed list of symbols)</li>
<li>NEW: added command line tool \ref JKQTMathTextRenderCmdLineTool that renders LaTeX into images, using it to generate the documentation images for JKQTMathText</li>

<li>removed/BREAKING change: removed the usage of some deprecated functions and objects (e.g. QMatrix)</li>
<li>removed/BREAKING change: removed the overlay elements (derived from JKQTPOverlayElement), which were not very well set up and are more confusing than useful.</li>
<li>improved/BREAKING change: geometric objects now use an adaptive drawing algorithm to represent curves (before e.g. ellipses were always separated into a fixed number of line-segments)</li>
<li>improved/BREAKING change: geometric elements constructor: removed all styling properties, added setStyle()-functions to replace them. This is necessary to better work with the extended Styling system</li>
<li>improved: constructors and access functions for several geometric objects (e.g. more constructors, additional functions to retrieve parameters in diferent forms, iterators for polygons, ...)</li>
<li>improved/BREAKING change: reworked class hierarchy of parsed function plots and declared several setters as slots.</li>
<li>improved/BREAKING change: reworked class hierarchy of bar & impulse charts.</li>
<li>improved/BREAKING change: reworked class hierarchy of range charts.</li>
<li>improved/BREAKING change: reworked class hierarchy of special line (step) graphs.</li>
<li>improved/BREAKING change: reworked class hierarchy of filled line graphs.</li>
<li>improved/BREAKING change: reworked class hierarchy of range plot elements (JKQTPVerticalRange and JKQTPHorizontalRange).</li>
<li>improved/BREAKING change: reworked class hierarchy of boxplots.</li>
<li>improved/BREAKING change: reworked class hierarchy of violin plots.</li>
<li>improved/BREAKING change: extended styling system for graphs.</li>
<li>improved/BREAKING change: reworked graph Base-Classes (promoted several setters to slots, added Q_PROPERTY- and Q_ENUM-declarations...)</li>
<li>improved/BREAKING change: made more functions and function parameters const</li>
<li>improved/BREAKING change: image plots now manage CONST-data, not plain pointer arrays... This is OK, since the raw data is never owned nor modified by the plot, only referenced!.</li>
<li>new: added support for high-dpi devices (thanks for <a href="https://github.com/jkriege2/JKQtPlotter/pull/55">PR #55: Enable high-dpi support for plots </a> by <a href="https://github.com/akenmorris">user:akenmorris</a>.</li>
<li>new: added geometric plot objects JKQTPGeoArrow to draw arrows (aka lines with added line-end decorators, also extended JKQTPGeoLine, JKQTPGeoInfiniteLine, JKQTPGeoPolyLines to draw line-end decorator (aka arrows)</li>
<li>new: all geometric objects can either be drawn as graphic element (i.e. lines are straight line, even on non-linear axes), or as mathematical curve (i.e. on non-linear axes, lines become the appropriate curve representing the linear function, connecting the given start/end-points). The only exceptions are ellipses (and the derived arcs,pies,chords), which are always drawn as mathematical curves</li>
<li>new: a new graph class JKQTPXYFunctionLineGraph draws parametric 2D curves ( \\f$ [x,y] = f(t) \\f$ ), see \ref JKQTPlotterEvalCurves for an example</li>
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.
<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: 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>
This is the final version of JKQTPlotter, which is still compatible with the <a href="https://github.com/jkriege2/QuickFit3">QuickFit 3.0</a> code base. It contains minor changes as compared to \ref page_whatsnew_V2015_10 "v2015.10":
This is the initial release of the library. It was developed initially as part of <a href="https://github.com/jkriege2/QuickFit3">QuickFit 3.0</a> and then separated out into a separate repository.
