v5.0.0-beta1

[jkriege2]

First Beta-Release for upcoming 5.0.0 of JKQtPlotter

Changes, compared to v4.0.0 include:

General/Build-System:

• BREAKING: renamed library JKQTCommonStatisticsAndMath to JKQTMath. Note: A CMake-ALIAS-Library JKQTCommonStatisticsAndMath was also added to ease transition for users
• BREAKING: JKQTFastPlotter class and library are now deprecated and will be removed in future versions!
• BREAKING: The QMake build system is deprecated and will not get the same love and atttention as the recommended CMake system. The QMake scripts might be removed in future versions!
• FIXED/SECURITY not using sprintf() any more ... replaced by e.g. snprintf() , which is more secure.
• FIXED issue #102: Fix CMake Compile Error: JKQTCommonLib no properly linked in JKQTMath static build (thanks to user:Neumann-A for reporting)
• CLEANUP (BREAKING) of library structure
• NEW: Using precompiled headers in CMake-build to speed up build times
• NEW/BREAKING: split jkqtcommon into basic tools and jkqtmath for advanced math tools not used by all libs
• NEW: When using a MSVC compiler, the generated PDB files are installed to CMAKE_INSTALL_PREFIX/bin/
• NEW: Added CMake option JKQtPlotter_BUILD_WITH_TIMING_INFO_OUTPUT, which activates several runtime-measurement guards of type JKQTPAutoOutputTimer (output via qDebug())
• NEW/BREAKING: provide general targets JKQTPlotter5/6::JKQTPlotter5/6, JKQTPlotter5/6::JKQTMathText5/6, ... which are independent of the type of build (shared/static)
• NEW/BREAKING: refactor CMake-Code, so static/dynamic switch is done via BUILD_SHARED_LIBS, which retires JKQtPlotter_BUILD_STATIC_LIBS, JKQtPlotter_BUILD_SHARED_LIBS and removes the capability to build static and shared libraries in one location (fixes issue Fix CMake usage for downstream consumers. #104)
• NEW: prepareed library for CMake's FetchContent-API
• NEW: the different sub-libraries JKQTPlotter, JKQTFastPlotter (DEPRECATED), JKQTMath, JKQTMathText can be activated/deactivated with CMake options JKQtPlotter_BUILD_LIB_JKQTPLOTTER, JKQtPlotter_BUILD_LIB_JKQTFASTPLOTTER, JKQtPlotter_BUILD_LIB_JKQTMATHTEXT, JKQtPlotter_BUILD_LIB_JKQTMATH

• NEW CSS-parser JKQTPCSSParser in order to parse e.g. linear-gradient() specifications in jkqtp_String2QBrushStyleExt()
  JKQTPlotter:

JKQTPlotter

• BREAKING/REWORKED: Updated default styling of graphs. They are now more modern!
• BREAKING/REWORKED: Implement better/more access functions to the graphs (inlcuding sorting, moving up/down, appending/prepending, graphs-iterators ...), solves issue #97, thanks to user:sim186 for bringing this up
• BREAKING/FIXED: fixed issue #96: JKQTPlotter::saveAsPixelImage() does not add a border around the image any longer (can be reacivated by a new optional function parameter), thanks to user:nmielcarek for reporting
• BREAKING/FIXED: JKQTPXFunctionLineGraph and JKQTPYFunctionLineGraph do no longer contribute to auto-scaling, as that depends on the current plot-axes (hen-egg-problem).
• BREAKING/FIXED: graph symbols were not properly applied when reading styles (in fact they were shuffled under some circumstances)
• BREAKING/NEW: rework layouting of keys/legends: new classes JKQTPBaseKey, JKQTPMainKey ... and removed several styling function for the main key from JKQTBasePlotter and JKQTPlotter (these are now accessible via JKQTBasePlotter::getMainKey()
• BREAKING/DEPRECATED: deprecated JKQTBasePlotter::zoom() and JKQTPlotter::zoom(), use JKQTBasePlotter::setXY() and JKQTPlotter::setXY() instead
• FIXED issue described in #62: Fix custom labels draw, because giving exactly two label-strings did not display all of them, thanks to user:FalsinSoft
• FIXED issue #70: Typo in jkqtplotter/CMakeLists.txt, thanks to user:tedlinlab

• FIXED issue #73: Symbol thickness differs in actual plot and legend, thanks to user:sim186
• FIXED plot-size calculation for filled graphs
• FIXED issue Problem with mouse coordinate(s) in JKQTPlotter::wheelEvent() #98: Signal JKQTPlotter::plotMouseWheelOperated() was called with wrong x/y-position-coordinates, thanks to user:fpalazzolo for reporting this bug
• FIXED: first symbol in symbols rotation was never used
• FIXED: color palettes with few entries (i.e. "step"-palettes) were not applied correctly
• FIXED: fixes strange rendering with distortions (especially in text!), by correcting size calculation of internal image buffer
• FIXED: exporting gridPrinting plots when using only a JKQTBasePlotter
• FIXED: fixed impleentations of JKQTPlotter::beginGraphs(), which actually returned the end-iterator (COPY-PASTE-ERROR!!!)
• FIXED issue #99: Clipping of Tick Labels: for horizontal axes, additional space at the left and/or right of the plot is allowed so labels are no longer clipped (thanks to user:allenbarnett5 for reporting)
• FIXED issue #99: Height of one-column key/legend was too large (thanks to user:allenbarnett5 for reporting)
• FIXED issue mentioned in #110: Lock the panning action to certain values: View zooms in, when panning close to AbosluteXY (thanks to user:sim186 for reporting)
• FIXED: jkqtpstatSum() and jkqtpstatSumSqr() did not work, as a non-existing function is called internally
• FIXED removed unnecessary operators (<,>,<=,>=) from JKQTPColumnIterator and JKQTPColumnConstIterator, which lead to exceptions on some compilers (MSVC)
• FIXED/IMPROVED issue #100: Add option to disable resize delay feature by setting the delay to zero (thanks to user:fpalazzolo for reporting)
• FIXED symmetry when zooming with JKQTBasePlotter::zoomIn() or JKQTBasePlotter::zoomOut()
• FIXED/NEW: placement of plot-title (was not centerd in its box, but glued to the bottom) by adding a plotstyle parameter JKQTBasePlotterStyle::plotLabelOffset
• FIXED/REWORKED issue #111: Can't write to PDF files with JKQTPlotter::saveImage() when passing a filename ending in ".pdf" (thanks to user:fpalazzolo for reporting):
  While fixing this issue, the functions JKQTBasePlotter::saveImage() etc. gained a bool return value to indicate whether sacing was successful.
• IMPROVED/FIXED outside space requirements for color bars. Text was sometime too close to the plot border.
• FIXED issue #140: addGraph function return value by adding return values to all addGraph()-Variants in JKQTPlotter (to mirror the interface of JKQTBasePlotter), (thanks to user:sajadblog
• REWORKED JKQTBasePlotter::saveData() with a more consistent interface and a bool return value to indicate success or failure + improved documentation, added methods to JKQTPSaveDataAdapter that allow to specify file extensions and an ID for the plugin.
• REWORKED: separation and gruping factor for barcharts on autoscaling
• REORGANIZED: separated line-graphs from jkqtpscatter.h/.cpp into jkqtplines.h/.cpp
• IMPROVED: QT6-compatibility by removing deprecated warnings
• IMPROVED: added missing override declarations
• IMPROVED: JKQTPlotter::jkqtp_RESIZE_DELAY is thread-safe now (atomic)
• IMPROVED: Using axis's tick label formating properties to format values in data-tooltips (e.g. dates will appear formated as such)
• IMPROVED/REWORKED: reworked JKQTPErrorPlotstyle and error indicator plotting so error-inidcators can be specified as ORed combination of flags from JKQTPErrorPlotstyleElements, added additional error indicator styles (half-bars, arrows...)
• IMPROVED/REWORKED: reworked JKQTPCADrawMode and coordinate axis drawing so the draw mide can be specified as ORed combination of flags from JKQTPCADrawModeElements, added flags to draw arrows at the end of the axis line
• IMPROVED/REWORKED: coordinate axis code was refactored
• IMPROVED/REWORKED: zomm/pan by mouse-wheel: now there are modes that support zoomin AND panning by trakpad and mouse-wheel simultaneously! This can only be implemented using heuristics, due to the way that Qt handles track-pad events, but the current solution should at least improve the behaviour seen before. Mainly jkqtpmwaZoomByWheelAndTrackpadPan was introduced into JKQTPMouseWheelActions und is set as default mode: Here JKQTPlotter tries to distinguish the QWheelEvent s sent by an actual mouse wheel and a trackpad.
• IMPROVED/REWORKED: better example graphs in Tutorial (JKQTPlotter): Styling a JKQtPlotter .
• IMPROVED/REWORKED: legend/key positioning as combination of 3 values, e.g. JKQTPKeyOutsideTop|JKQTPKeyTop|JKQTPKeyRight or JKQTPKeyInside|JKQTPKeyTopJKQTPKeyRight
• IMPROVED/REWORKED: The functions JKQTBasePlotter::saveImage(), JKQTBasePlotter::saveAsPixelImage(), JKQTBasePlotter::saveAsPDF(), JKQTBasePlotter::saveSVG(), ... gained a bool return value to indicate whether sacing was successful.
• IMPROVED/REWORKED: More save...() functions will appear in the API of JKQTPlotter, so you don't have to go via JKQTPlotter::getPlotter(). These are merely forwarding the call to the internel JKQTBasePlotter instance.
• IMPROVED: documentation of styles: automatized doc image generation.
• IMPROVED: axis labeling: there were some minor differences between compilers
• IMPROVED: jkqtp_floattounitstr()/jkqtp_floattolatexunitstr(): add all SI-Prefixes from 10^-30...10^30
• RENAMED JKQTPDatastore::addColumnCalculatedFromColumn() to JKQTPDatastore::addCalculatedColumnFromColumn(), which is more in line with the other add...()-function names. Aliases with the old function names remain for compatibility
• NEW: JKQTPFilledCurveXGraph and JKQTPFilledCurveYGraph can now plot wiggle plots with different fill styles above and below the baseline (feature request #68 Wiggle Plots from user:xichaoqiang
• 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!
• NEW: new "seaborn" style for plots, see Styling System
• NEW/BREAKING CHANGE: changed JKQTPColorDerivationMode into a struct, which extends its capabilities above the previously available few enum-items
• NEW: added debug-feature to show boxes around text in the plot
• 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 #81, many thanks to user:sufuk for contributing part of the code and supplying the idea!
• NEW: improved plotting speed for line-graphs by drawing a series of single lines instead of a polyline in some cases
• NEW: improved plotting speed for line-graphs by a compression algorithm (see JKQTPGraphLinesCompressionMixin) that removes overlaying lines (e.g. in JKQTPXYLineGraph)
• NEW: improved plotting speed for line-graphs by a clipping algorithm (applies to JKQTPXYLineGraph, JKQTPGraphErrorStyleMixin, JKQTPSpecialLineHorizontalGraph, JKQTPSpecialLineVerticalGraph and others)
• NEW: improved plotting speed for scatter-graphs by not calling draw functions for symbols outside the plot window (e.g. in JKQTPXYLineGraph)
• NEW: added JKQTBasePlotter::grabPixelImage() and JKQTPlotter::grabPixelImage(), which grab the plotter into a QImage
• NEW: added option to not display the preview dialog to JKQTBasePlotter::copyPixelImage() and JKQTPlotter::copyPixelImage()
• NEW: added simple scatter plot JKQTPXYScatterGraph
• NEW: made resize-timer status accessible from outside via JKQTPlotter::isResizeTimerRunning()
• NEW: made it's delay a global static variable that can be set and red with JKQTPlotter::setGlobalResizeDelay() and JKQTPlotter::getGlobalResizeDelay()
• NEW: Using JKQTMathText::useGuiFonts() for FONT rendering by default
• NEW: added the option to draw a character from a font as symbol (JKQTPCharacterSymbol+QChar('C').unicode() and JKQTPFilledCharacterSymbol+QChar('C').unicode())

• NEW: added property drawLineInForeground to JKQTPXYLineGraph and JKQTPXYParametrizedScatterGraph
• NEW: added JKQTPXYGraph::setKeyColumn()/JKQTPXYGraph::getKeyColumn() and JKQTPXYGraph::setValueColumn()/JKQTPXYGraph::getValueColumn() and corresponding functions in other classes. In most graph classes they point to xColumn for key and yColumn for values. These functions are virtual and overwritten in derived classes with horizontally oriented graphs, where they point to yColumn for key and yColumn for value. This way you can write generic code with classes for both orientations.
• NEW: added new error indicator styles JKQTPErrorHalfBarsOutwards, JKQTPErrorHalfBarsInwards, JKQTPErrorHalfBarsAbove, JKQTPErrorHalfBarsBelow which are especially useful for barcharts
• NEW: Added signals JKQTBasePlotter::beforeExporting()/JKQTBasePlotter::afterExporting() and JKQTBasePlotterJKQTBasePlotter:beforePrinting()/JKQTBasePlotter::afterPrinting() which allow to modify the plot just before and just after an export/print
  NEW: Added new JKQTPCALabelType elements (JKQTPCALTfrac...), so axis label ticks can be displayed as fractions 1/2 instead of 0.5
  JKQTPCALTscientific, so axis label ticks can be displayed as numbers in scientific notation like 1.2E-34
  JKQTPCALTprintf for general formatting with a printf-format string
  JKQTPCALTformat for general formatting with a std::format-format string (available for C++>=20 only!!!)
• NEW: all elements of a coordinate axis may have their own color now
• NEW: added possibility to scale the axis ticks by a factor (e.g. pi) to generate axes with ticks 0pi, 1pi, 2pi ...
• NEW: added option to draw a zero axis to JKQTPCoordinateAxis, which draws an axis at the origin of the coordinate system
• NEW: barcharts (derived from JKQTPBarGraphBase) can be configured to use different fill styles above and below the baseline, see JKQTPBarGraphBase::FillMode
• NEW: barcharts may have rounded corners now, via JKQTPBarGraphBase::setRectRadius()
• NEW: barcharts can be colored by a user-specified functor

• NEW: barcharts and impulse graphs may now draw their baseline as stylable line (default: off)
• NEW: secondary axes: added functionality to manage additional secondary axes in a JKQTPBasePlotter and to select which x-/y-Axis to use for drawing a JKQTPPlotElement
• NEW: You can use additional syntax derived from CCS to define colors in style.ini.files (or when using jkqtp_String2QColor() ): You can use full CSS-color syntax with functions "rgb(R,G,B)", "rgba(...)", "hsl(...)", "hsv(...)", "gray(...)", "green(...)", "red(...)", "blue(...)".
• NEW: several new color palettes (especially stepped/categorial palettes), e.g. JKQTPMathImageColorPalette::JKQTPMathImageOkabeIto_STEP, JKQTPMathImageColorPalette::JKQTPMathImageIBMColorBlindSafe, JKQTPMathImageColorPalette::JKQTPMathImageIBMColorBlindSafe_STEP, ...
• NEW: add color palettes from Green's HELIX method, see https://arxiv.org/abs/1108.5083, also see https://jiffyclub.github.io/palettable/cubehelix/, see JKQTPCreateGreensCubeHelixLUT() and e.g. JKQTPMathImageCubeHelixClassic, JKQTPMathImageCubeHelix1, ...
• NEW: Using Q_SIGNALS/Q_SLOTS instead of signals/slots MOC-keywords ... this allows for interoperability with other signals/slots frameworks, thanks to user:nickmontini for the proposal
• NEW: you can use any (preferably stepped/categorial) JKQTPMathImageColorPalette as default graph colors list in a style.ini file, by setting auto_styles/use_color_from_palette=PALETTE_NAME
• NEW: added entry for JKQTBasePlotterStyle::plotLabelColor to set the plot label color
• NEW: added JKQTBasePlotterStyle::plotLabelTopBorder to set the spacing between top and plot label
• NEW: Due to addition of JKQTMathText::setFontOptions() and the matchign extension of JKQTMathText::setFontSpecial() (see below) you can now add modifiers like +BOLD+ITALIC to any font-name provided to JKQTPlotter and in style INI-files
• NEW: added JKQTPLabelMinBesides and JKQTPLabelMaxBesides to JKQTPLabelPosition, so labels can be set besides the axes
• NEW/REWORKED all functions in JKQTBasePlotter are re-entrant, i.e. different instances can be used from different threads in parallel (although there is some overhead due to shared caches between the threads!). This is demonstrated and discussed in Example (JKQTPlotter): Multi-Threaded (Parallel) Plotting .
• NEW: allow linear-gradient(), currentcolor, ... in brush definitions of style.ini-file ... and using it is cyberpunk and dark styles
• NEW: style simple_noaxes.ini

• NEW: JKQTPParametrizedVectorFieldGraph for drawing color-coded vector fields/quiver plots (+example Example (JKQTPlotter): Vector Field Plot Example)
• NEW: JKQTPFinancialGraph for drawing candlestick or OHLC graphs of financial data, such as stock amrket prices (+example Example (JKQTPlotter): Financial Chart (Candlestick/OHLC) Example)
• NEW: stacked barcharts may have a small separation (default 1pt)
• NEW: autoscaling for barcharts works now, also when stacked and unstacked charts are combined in one plot
• NEW: JKQTPGeoBezierCurve for drawing bezier curves of degree 1-4 (+example Example (JKQTPlotter): Plotting Bezier Curves)
• NEW: added JKQTPCoordinateAxis::setRangeFixed() which disables changing the axis range (and thus the zoom)
• NEW: added JKQTPCoordinateAxis::getMin() and JKQTPCoordinateAxis::getMax() getters
• NEW: added example Example (JKQTPlotter): Using a QScrollbar together with JKQtPlotter
