-#### Version 1.3.2 released on 22.12.15 ####
-
- Bugfixes [Backported from 2.0.0 branch]:
- - Fixed possible crash when having a QCPGraph with scatters only and a non-transparent main/fill brush of the graph
- - Fixed QCPItemPixmap not updating internally cached scaled pixmap if new pixmap set with same scaled dimensions
- - When using log axis scale and zooming out as far as possible (~1e-280..1e280), axis doesn't end up in (via mouse) unrecoverable range with strange axis ticks anymore
- - Axis tick label algorithm for beautifully typeset powers now checks whether "e" in tick label is actually part of a number before converting the exponent to superscript
- - Fixed QCustomPlot::moveLayer performing incorrect move and possible crash in certain situations
- - Fixed possible crash on QCustomPlot destruction due to wrong QObject-hierarchy. Only occurs if a QCPAxisRect is removed from the normal QCustomPlot destruction hierarchy by taking it out of its layout
- - Fixed possible freeze when data values become infinity after coord-to-pixel transformation (e.g. maximally zoomed out log axis), and line style is not solid (e.g. dashed) or phFastPolylines is disabled
-
- Other [Backported from 2.0.0 branch]:
- - A few documentation fixes/improvements
- - Qt5.5 compatibility (If you use PDF export, test your outputs, as output dimensions might change when switching Qt versions -- QCP does not try to emulate previous Qt version behaviour here)
- - QCP now includes <QtPrintSupport/QtPrintSupport> instead of just <QtPrintSupport> because some users had problems with the latter. Please report if you now experience issues due to the new include.
-
-#### Version 1.3.1 released on 25.04.15 ####
-
- Bugfixes:
- - Fixed bug that prevented automatic axis rescaling when some graphs/curves had only NaN data points
- - Improved QCPItemBracket selection boundaries, especially bsCurly and bsCalligraphic
- - Fixed bug of axis rect and colorscale background shifted downward by one logical pixel (visible in scaled png and pdf export)
- - Replot upon mouse release is now only performed if a selection change has actually happened (improves responsivity on particularly complex plots)
- - Fixed bug that allowed scatter-only graphs to be selected by clicking the non-existent line between scatters
- - Fixed crash when trying to select a scatter-only QCPGraph whose only points in the visible key range are at identical key coordinates and vertically off-screen, with adaptive sampling enabled
- - Fixed pdf export of QCPColorMap with enabled interpolation (didn't appear interpolated in pdf)
- - Reduced QCPColorMap jitter of internal cell boundaries for small sized maps when viewed with high zoom, by applying oversampling factors dependant on map size
- - Fixed bug of QCPColorMap::fill() not causing the buffered internal image map to be updated, and thus the change didn't become visible immediately
- - Axis labels with size set in pixels (setPixelSize) instead of points now correctly calculate the exponent's font size if beautifully typeset powers are enabled
- - Fixed QCPColorMap appearing at the wrong position for logarithmic axes and color map spanning larger ranges
-
- Other:
- - Pdf export used to embed entire QCPColorMaps, potentially leading to large files. Now only the visible portion of the map is embedded in the pdf
- - Many documentation fixes and extensions, style modernization
- - Reduced documentation file size (and thus full package size) by automatically reducing image palettes during package build
- - Fixed MSVC warning message (at warning level 4) due to temporary QLists in some foreach statements

- - Fixed conflict with MSVC-specific keyword "interface" in text-document-integration example
- - Fixed QCPScatterStyle bug ignoring the specified pen in the custom scatter shape constructor
- - Fixed bug (possible crash) during QCustomPlot teardown, when a QCPLegend that has no parent layout (i.e. was removed from layout manually) gets deleted

-
- Added features:
- - Adaptive Sampling for QCPGraph greatly improves performance for high data densities (see QCPGraph::setAdaptiveSampling)
- - QCPColorMap plottable with QCPColorScale layout element allows plotting of 2D color maps
- - QCustomPlot::savePdf now has additional optional parameters pdfCreator and pdfTitle to set according PDF metadata fields
- - QCustomPlot::replot now allows specifying whether the widget update is immediate (repaint) or queued (update)
- - QCPRange operators +, -, *, / with double operand for range shifting and scaling, and ==, != for range comparison
- - Layers now have a visibility property (QCPLayer::setVisible)
- - static functions QCPAxis::opposite and QCPAxis::orientation now offer more convenience when handling axis types
- - added notification signals for selectability change (selectableChanged) on all objects that have a selected/selectable property
- - added notification signal for QCPAxis scaleType property

-
- Bugfixes:
- - Fixed assert halt, when QCPAxis auto tick labels not disabled but nevertheless a custom non-number tick label ending in "e" given
- - Fixed painting glitches when QCustomPlot resized inside a QMdiArea or under certain conditions inside a QLayout
- - If changing QCPAxis::scaleType and thus causing range sanitizing and a range modification, rangeChanged wouldn't be emitted
- - Fixed documentation bug that caused indentation to be lost in code examples
- Bugfixes after beta:
- - Fixed bug that caused crash if clicked-on legend item is removed in mousePressEvent.
- - On some systems, font size defaults to -1, which used to cause a debug output in QCPAxisPainterPrivate::TickLabelDataQCP. Now it's checked before setting values based on the default font size.
- - When using multiple axes on one side, setting one to invisible didn't properly compress the freed space.
- - Fixed bug that allowed selection of plottables when clicking in the bottom or top margin of a QCPAxisRect (outside the inner rect)
-
- Other:
- - In method QCPAbstractPlottable::getKeyRange/getValueRange, renamed parameter "validRange" to "foundRange", to better reflect its meaning (and contrast it from QCPRange::validRange)
- - QCPAxis low-level axis painting methods exported to QCPAxisPainterPrivate
-
-#### Version 1.1.1 released on 09.12.13 ####
-
- Bugfixes:
- - Fixed bug causing legends blocking input events from reaching underlying axis rect even if legend is invisible

-
- Bugfixes:

- - QCPGraph::rescaleAxes/rescaleKeyAxis/rescaleValueAxis are no longer virtual (never were in base class, was a mistake)
- - Fixed bugs in QCPAxis::items and QCPAxisRect::items not properly returning associated items and potentially stalling
-
- Other:
- - Internal change from QWeakPointer to QPointer, thus got rid of deprecated Qt functionality
- - Qt5.1 and Qt5.2 (beta1) compatibility
- - Release packages now extract to single subdirectory and don't place multiple files in current working directory
-
-#### Version 1.0.1 released on 05.09.13 ####

- - documentation images are now properly shown when viewed with Qt Assistant
- - fixed various documentation mistakes
-
- Other:
- - Adapted documentation style sheet to better match Qt5 documentation
-
-#### Version 1.0.0 released on 01.08.13 ####
-
- Quick Summary:
- - Layout system for multiple axis rects in one plot
- - Multiple axes per side
- - Qt5 compatibility
- - More flexible and consistent scatter configuration with QCPScatterStyle
- - Various interface cleanups/refactoring
- - Pixmap-cached axis labels for improved replot performance
-
- Changes that break backward compatibility:
- - QCustomPlot::axisRect() changed meaning due to the extensive changes to how axes and axis rects are handled
- it now returns a pointer to a QCPAxisRect and takes an integer index as parameter.
- - QCPAxis constructor changed to now take QCPAxisRect* as parent
- - setAutoMargin, setMarginLeft/Right/Top/Bottom removed due to the axis rect changes (see QCPAxisRect::setMargins/setAutoMargins)
- - setAxisRect removed due to the axis rect changes
- - setAxisBackground(-Scaled/-ScaledMode) now moved to QCPAxisRect as setBackground(-Scaled/ScaledMode) (access via QCustomPlot::axisRects())
- - QCPLegend now is a QCPLayoutElement
- - QCPAbstractPlottable::drawLegendIcon parameter "rect" changed from QRect to QRectF
- - QCPAbstractLegendItem::draw second parameter removed (position/size now handled via QCPLayoutElement base class)
- - removed QCPLegend::setMargin/setMarginLeft/Right/Top/Bottom (now inherits the capability from QCPLayoutElement::setMargins)
- - removed QCPLegend::setMinimumSize (now inherits the capability from QCPLayoutElement::setMinimumSize)
- - removed enum QCPLegend::PositionStyle, QCPLegend::positionStyle/setPositionStyle/position/setPosition (replaced by capabilities of QCPLayoutInset)
- - QCPLegend transformed to work with new layout system (almost everything changed)
- - removed entire title interface: QCustomPlot::setTitle/setTitleFont/setTitleColor/setTitleSelected/setTitleSelectedFont/setTitleSelectedColor and
- the QCustomPlot::iSelectTitle interaction flag (all functionality is now given by the layout element "QCPPlotTitle" which can be added to the plot layout)
- - selectTest functions now take two additional parameters: bool onlySelectable and QVariant *details=0
- - selectTest functions now ignores visibility of objects and (if parameter onlySelectable is true) does not anymore ignore selectability of the object
- - moved QCustomPlot::Interaction/Interactions to QCP namespace as QCP::Interaction/Interactions
- - moved QCustomPlot::setupFullAxesBox() to QCPAxisRect::setupFullAxesBox. Now also accepts parameter to decide whether to connect opposite axis ranges
- - moved range dragging/zooming interface from QCustomPlot to QCPAxisRect (setRangeDrag, setRangeZoom, setRangeDragAxes, setRangeZoomAxes,...)
- - rangeDrag/Zoom is now set to Qt::Horizontal|Qt::Vertical instead of 0 by default, on the other hand, iRangeDrag/Zoom is unset in interactions by
- default (this makes enabling dragging/zooming easier by just adding the interaction flags)
- - QCPScatterStyle takes over everything related to handling scatters in all plottables
- - removed setScatterPen/Size on QCPGraph and QCPCurve, removed setOutlierPen/Size on QCPStatisticalBox (now handled via QCPScatterStyle)
- - modified setScatterStyle on QCPGraph and QCPCurve, and setOutlierStyle on QCPStatisticalBox, to take QCPScatterStyle
- - axis grid and subgrid are now reachable via the QCPGrid *QCPAxis::grid() method. (e.g. instead of xAxis->setGrid(true), write xAxis->grid()->setVisible(true))
-
- Added features:
- - Axis tick labels are now pixmap-cached, thus increasing replot performance (in usual setups by about 24%). See plotting hint phCacheLabels which is set by default
- - Advanced layout system, including the classes QCPLayoutElement, QCPLayout, QCPLayoutGrid, QCPLayoutInset, QCPAxisRect
- - QCustomPlot::axisRects() returns all the axis rects in the QCustomPlot.
- - QCustomPlot::plotLayout() returns the top level layout (initially a QCPLayoutGrid with one QCPAxisRect inside)
- - QCPAxis now may have an offset to the axis rect (setOffset)
- - Multiple axes per QCPAxisRect side are now supported (see QCPAxisRect::addAxis)
- - QCustomPlot::toPixmap renders the plot into a pixmap and returns it
- - When setting tick label rotation to +90 or -90 degrees on a vertical axis, the labels are now centered vertically on the tick height
- (This allows space saving vertical tick labels by having the text direction parallel to the axis)
- - Substantially increased replot performance when using very large manual tick vectors (> 10000 ticks) via QCPAxis::setTickVector
- - QCPAxis and QCPAxisRect now allow easy access to all plottables(), graphs() and items() that are associated with them
- - Added QCustomPlot::hasItem method for consistency with plottable interface, hasPlottable
- - Added QCPAxisRect::setMinimumMargins as replacement for hardcoded minimum axis margin (15 px) when auto margin is enabled
- - Added Flags type QCPAxis::AxisTypes (from QCPAxis::AxisType), used in QCPAxisRect interface
- - Automatic margin calculation can now be enabled/disabled on a per-side basis, see QCPAxisRect::setAutoMargins
- - QCPAxisRect margins of multiple axis rects can be coupled via QCPMarginGroup
- - Added new default layers "background" and "legend" (QCPAxisRect draws its background on the "background" layer, QCPLegend is on the "legend" layer by default)
- - Custom scatter style via QCP::ssCustom and respective setCustomScatter functions that take a QPainterPath
- - Filled scatters via QCPScatterStyle::setBrush
- Added features after beta:
- - Added QCustomPlot::toPainter method, to allow rendering with existing painter
- - QCPItemEllipse now provides a center anchor
-
- Bugfixes:
- - Fixed compile error on ARM
- - Wrong legend icons were displayed if using pixmaps for scatters that are smaller than the legend icon rect
- - Fixed clipping inaccuracy for rotated tick labels (were hidden too early, because the non-rotated bounding box was used)
- - Fixed bug that caused wrong clipping of axis ticks and subticks when the ticks were given manually by QCPAxis::setTickVector
- - Fixed Qt5 crash when dragging graph out of view (iterator out of bounds in QCPGraph::getVisibleDataBounds)
- - Fixed QCPItemText not scaling properly when using scaled raster export
- Bugfixes after beta:
- - Fixed bug that clipped the rightmost pixel column of tick labels when caching activated (only visible on windows for superscript exponents)
- - Restored compatibility to Qt4.6
- - Restored support for -no-RTTI compilation
- - Empty manual tick labels are handled more gracefully (no QPainter qDebug messages anymore)
- - Fixed type ambiguity in QCPLineEnding::draw causing compile error on ARM
- - Fixed bug of grid layouts not propagating the minimum size from their child elements to the parent layout correctly
- - Fixed bug of child elements (e.g. axis rects) of inset layouts not properly receiving mouse events
-
- Other:
- - Opened up non-amalgamated project structure to public via git repository
-
-#### Version released on 09.06.12 ####
-
- Quick Summary:
- - Items (arrows, text,...)
- - Layers (easier control over rendering order)
- - New antialiasing system (Each objects controls own antialiasing with setAntialiased)
- - Performance Improvements
- - improved pixel-precise drawing
- - easier shared library creation/usage
-
- Changes that (might) break backward compatibility:
- - enum QCPGraph::ScatterSymbol was moved to QCP namespace (now QCP::ScatterSymbol).
- This replace should fix your code: "QCPGraph::ss" -> "QCP::ss"
- - enum QCustomPlot::AntialiasedElement and flag QCustomPlot::AntialiasedElements was moved to QCP namespace
- This replace should fix your code: "QCustomPlot::ae" -> "QCP::ae"
- - the meaning of QCustomPlot::setAntialiasedElements has changed slightly: It is now an override to force elements to be antialiased. If you want to force
- elements to not be drawn antialiased, use the new setNotAntialiasedElements. If an element is mentioned in neither of those functions, it now controls
- its antialiasing itself via its "setAntialiased" function(s). (e.g. QCPAxis::setAntialiased(bool), QCPAbstractPlottable::setAntialiased(bool),
- QCPAbstractPlottable::setAntialiasedScatters(bool), etc.)
- - QCPAxis::setTickVector and QCPAxis::setTickVectorLabels no longer take a pointer but a const reference of the respective QVector as parameter.
- (handing over a pointer didn't give any noticeable performance benefits but was inconsistent with the rest of the interface)
- - Equally QCPAxis::tickVector and QCPAxis::tickVectorLabels don't return by pointer but by value now
- - QCustomPlot::savePngScaled was removed, its purpose is now included as optional parameter "scale" of savePng.
- - If you have derived from QCPAbstractPlottable: all selectTest functions now consistently take the argument "const QPointF &pos" which is the test point in pixel coordinates.
- (the argument there was "double key, double value" in plot coordinates, before).
- - QCPAbstractPlottable, QCPAxis and QCPLegend now inherit from QCPLayerable
- - If you have derived from QCPAbstractPlottable: the draw method signature has changed from "draw (..) const" to "draw (..)", i.e. the method
- is not const anymore. This allows the draw function of your plottable to perform buffering/caching operations, if necessary.
-
- Added features:
- - Item system: QCPAbstractItem, QCPItemAnchor, QCPItemPosition, QCPLineEnding. Allows placing of lines, arrows, text, pixmaps etc.
- - New Items: QCPItemStraightLine, QCPItemLine, QCPItemCurve, QCPItemEllipse, QCPItemRect, QCPItemPixmap, QCPItemText, QCPItemBracket, QCPItemTracer
- - QCustomPlot::addItem/itemCount/item/removeItem/selectedItems
- - signals QCustomPlot::itemClicked/itemDoubleClicked
- - the QCustomPlot interactions property now includes iSelectItems (for selection of QCPAbstractItem)
- - QCPLineEnding. Represents the different styles a line/curve can end (e.g. different arrows, circle, square, bar, etc.), see e.g. QCPItemCurve::setHead
- - Layer system: QCPLayerable, QCPLayer. Allows more sophisticated control over drawing order and a kind of grouping.
- - QCPAbstractPlottable, QCPAbstractItem, QCPAxis, QCPGrid, QCPLegend are layerables and derive from QCPLayerable
- - QCustomPlot::addLayer/moveLayer/removeLayer/setCurrentLayer/layer/currentLayer/layerCount
- - Initially there are three layers: "grid", "main", and "axes". The "main" layer is initially empty and set as current layer, so new plottables/items are put there.
- - QCustomPlot::viewport now makes the previously inaccessible viewport rect read-only-accessible (needed that for item-interface)
- - PNG export now allows transparent background by calling QCustomPlot::setColor(Qt::transparent) before savePng
- - QCPStatisticalBox outlier symbols may now be all scatter symbols, not only hardcoded circles.
- - perfect precision of scatter symbol/error bar drawing and clipping in both antialiased and non-antialiased mode, by introducing QCPPainter
- that works around some QPainter bugs/inconveniences. Further, more complex symbols like ssCrossSquare used to look crooked, now they look good.
- - new antialiasing control system: Each drawing element now has its own "setAntialiased" function to control whether it is drawn antialiased.
- - QCustomPlot::setAntialiasedElements and QCustomPlot::setNotAntialiasedElements can be used to override the individual settings.
- - Subclasses of QCPAbstractPlottable can now use the convenience functions like applyFillAntialiasingHint or applyScattersAntialiasingHint to
- easily make their drawing code comply with the overall antialiasing system.
- - QCustomPlot::setNoAntialiasingOnDrag allows greatly improved performance and responsiveness by temporarily disabling all antialiasing while
- the user is dragging axis ranges
- - QCPGraph can now show scatter symbols at data points and hide its line (see QCPGraph::setScatterStyle, setScatterSize, setScatterPixmap, setLineStyle)
- - Grid drawing code was sourced out from QCPAxis to QCPGrid. QCPGrid is mainly an internal class and every QCPAxis owns one. The grid interface still
- works through QCPAxis and hasn't changed. The separation allows the grid to be drawn on a different layer as the axes, such that e.g. a graph can
- be above the grid but below the axes.
- - QCustomPlot::hasPlottable(plottable), returns whether the QCustomPlot contains the plottable
- - QCustomPlot::setPlottingHint/setPlottingHints, plotting hints control details about the plotting quality/speed
- - export to jpg and bmp added (QCustomPlot::saveJpg/saveBmp), as well as control over compression quality for png and jpg
- - multi-select-modifier may now be specified with QCustomPlot::setMultiSelectModifier and is not fixed to Ctrl anymore
-
- Bugfixes:
- - fixed QCustomPlot ignores replot after it had size (0,0) even if size becomes valid again
- - on Windows, a repaint used to be delayed during dragging/zooming of a complex plot, until the drag operation was done.
- This was fixed, i.e. repaints are forced after a replot() call. See QCP::phForceRepaint and setPlottingHints.
- - when using the raster paintengine and exporting to scaled PNG, pen widths are now scaled correctly (QPainter bug workaround via QCPPainter)
- - PDF export now respects QCustomPlot background color (QCustomPlot::setColor), also Qt::transparent
- - fixed a bug on QCPBars and QCPStatisticalBox where auto-rescaling of axis would fail when all data is very small (< 1e-11)
- - fixed mouse event propagation bug that prevented range dragging from working on KDE (GNU/Linux)
- - fixed a compiler warning on 64-bit systems due to pointer cast to int instead of quintptr in a qDebug output
-
- Other:
- - Added support for easier shared library creation (including examples for compiling and using QCustomPlot as shared library)
- - QCustomPlot now has the Qt::WA_OpaquePaintEvent widget attribute (gives slightly improved performance).
- - QCP::aeGraphs (enum QCP::AntialiasedElement, previously QCustomPlot::aeGraphs) has been marked deprecated since version 02.02.12 and
- was now removed. Use QCP::aePlottables instead.
- - optional performance-quality-tradeoff for solid graph lines (see QCustomPlot::setPlottingHints).
- - marked data classes and QCPRange as Q_MOVABLE_TYPE
- - replaced usage of own macro FUNCNAME with Qt macro Q_FUNC_INFO
- - QCustomPlot now returns a minimum size hint of 50*50
-
-#### Version released on 31.03.12 ####
-
- Changes that (might) break backward compatibility:
- - QCPAbstractLegendItem now inherits from QObject
- - mousePress, mouseMove and mouseRelease signals are now emitted before and not after any QCustomPlot processing (range dragging, selecting, etc.)
-
- Added features:
- - Interaction system: now allows selecting of objects like plottables, axes, legend and plot title, see QCustomPlot::setInteractions documentation
- - Interaction system for plottables:
- - setSelectable, setSelected, setSelectedPen, setSelectedBrush, selectTest on QCPAbstractPlottable and all derived plottables
- - setSelectionTolerance on QCustomPlot
- - selectedPlottables and selectedGraphs on QCustomPlot (returns the list of currently selected plottables/graphs)
- - Interaction system for axes:
- - setSelectable, setSelected, setSelectedBasePen, setSelectedTickPen, setSelectedSubTickPen, setSelectedLabelFont, setSelectedTickLabelFont,
- setSelectedLabelColor, setSelectedTickLabelColor, selectTest on QCPAxis
- - selectedAxes on QCustomPlot (returns a list of the axes that currently have selected parts)
- - Interaction system for legend:
- - setSelectable, setSelected, setSelectedBorderPen, setSelectedIconBorderPen, setSelectedBrush, setSelectedFont, setSelectedTextColor, selectedItems on QCPLegend
- - setSelectedFont, setSelectedTextColor, setSelectable, setSelected on QCPAbstractLegendItem
- - selectedLegends on QCustomPlot
- - Interaction system for title:
- - setSelectedTitleFont, setSelectedTitleColor, setTitleSelected on QCustomPlot
- - new signals in accordance with the interaction system:
- - selectionChangedByUser on QCustomPlot
- - selectionChanged on QCPAbstractPlottable
- - selectionChanged on QCPAxis
- - selectionChanged on QCPLegend and QCPAbstractLegendItem
- - plottableClick, legendClick, axisClick, titleClick, plottableDoubleClick, legendDoubleClick, axisDoubleClick, titleDoubleClick on QCustomPlot
- - QCustomPlot::deselectAll (deselects everything, i.e. axes and plottables)
- - QCPAbstractPlottable::pixelsToCoords (inverse function to the already existing coordsToPixels function)
- - QCPRange::contains(double value)
- - QCPAxis::setLabelColor and setTickLabelColor
- - QCustomPlot::setTitleColor
- - QCustomPlot now emits beforeReplot and afterReplot signals. Note that it is safe to make two customPlots mutually call eachothers replot functions
- in one of these slots, it will not cause an infinite loop. (usefull for synchronizing axes ranges between two customPlots, because setRange alone doesn't replot)
- - If the Qt version is 4.7 or greater, the tick label strings in date-time-mode now support sub-second accuracy (e.g. with format like "hh:mm:ss.zzz").
-
- Bugfixes:
- - tick labels/margins should no longer oscillate by one pixel when dragging range or replotting repeatedly while changing e.g. data. This
- was caused by a bug in Qt's QFontMetrics::boundingRect function when the font has an integer point size (probably some rounding problem).
- The fix hence consists of creating a temporary font (only for bounding-box calculation) which is 0.05pt larger and thus avoiding the
- jittering rounding outcome.
- - tick label, axis label and plot title colors used to be undefined. This was fixed by providing explicit color properties.
-
- Other:
- - fixed some glitches in the documentation
- - QCustomPlot::replot and QCustomPlot::rescaleAxes are now slots
-
-#### Version released on 02.02.12 ####
-
- Changes that break backward compatibility:
- - renamed all secondary classes from QCustomPlot[...] to QCP[...]:
- QCustomPlotAxis -> QCPAxis
- QCustomPlotGraph -> QCPGraph
- QCustomPlotRange -> QCPRange
- QCustomPlotData -> QCPData
- QCustomPlotDataMap -> QCPDataMap
- QCustomPlotLegend -> QCPLegend
- QCustomPlotDataMapIterator -> QCPDataMapIterator
- QCustomPlotDataMutableMapIterator -> QCPDataMutableMapIterator
- A simple search and replace on all code files should make your code run again, e.g. consider the regex "QCustomPlot(?=[AGRDL])" -> "QCP".
- Make sure not to just replace "QCustomPlot" with "QCP" because the main class QCustomPlot hasn't changed to QCP.
- This change was necessary because class names became unhandy, pardon my bad naming decision in the beginning.
- - QCPAxis::tickLength() and QCPAxis::subTickLength() now each split into two functions for inward and outward ticks (tickLengthIn/tickLengthOut).
- - QCPLegend now uses QCPAbstractLegendItem to carry item data (before, the legend was passed QCPGraphs directly)
- - QCustomPlot::addGraph() now doesn't return the index of the created graph anymore, but a pointer to the created QCPGraph.
- - QCustomPlot::setAutoAddGraphToLegend is replaced by setAutoAddPlottableToLegend
-
- Added features:
- - Reversed axis range with QCPAxis::setRangeReversed(bool)
- - Tick labels are now only drawn if not clipped by the viewport (widget border) on the sides (e.g. left and right on a horizontal axis).
- - Zerolines. Like grid lines only with a separate pen (QCPAxis::setZeroLinePen), at tick position zero.
- - Outward ticks. QCPAxis::setTickLength/setSubTickLength now accepts two arguments for inward and outward tick length. This doesn't break
- backward compatibility because the second argument (outward) has default value zero and thereby a call with one argument hasn't changed its meaning.
- - QCPGraph now inherits from QCPAbstractPlottable
- - QCustomPlot::addPlottable/plottable/removePlottable/clearPlottables added to interface with the new QCPAbstractPlottable-based system. The simpler interface
- which only acts on QCPGraphs (addGraph, graph, removeGraph, etc.) was adapted internally and is kept for backward compatibility and ease of use.
- - QCPLegend items for plottables (e.g. graphs) can automatically wrap their texts to fit the widths, see QCPLegend::setMinimumSize and QCPPlottableLegendItem::setTextWrap.
- - QCustomPlot::rescaleAxes. Adapts axis ranges to show all plottables/graphs, by calling QCPAbstractPlottable::rescaleAxes on all plottables in the plot.
- - QCPCurve. For plotting of parametric curves.
- - QCPBars. For plotting of bar charts.
- - QCPStatisticalBox. For statistical box plots.
-
- Bugfixes:
- - Fixed QCustomPlot::removeGraph(int) not being able to remove graph index 0
- - made QCustomPlot::replot() abort painting when painter initialization fails (e.g. because width/height of QCustomPlot is zero)
- - The distance of the axis label from the axis ignored the tick label padding, this could have caused overlapping axis labels and tick labels
- - fixed memory leak in QCustomPlot (dtor didn't delete legend)
- - fixed bug that prevented QCPAxis::setRangeLower/Upper from setting the value to exactly 0.
-
- Other:
- - Changed default error bar handle size (QCustomPlotGraph::setErrorBarSize) from 4 to 6.
- - Removed QCustomPlotDataFetcher. Was deprecated and not used class.
- - Extended documentation, especially class descriptions.
-
-#### Version released on 15.01.12 ####
-
- Changes that (might) break backward compatibility:
- - QCustomPlotGraph now inherits from QObject
-
- Added features:
- - Added axis background pixmap (QCustomPlot::setAxisBackground, setAxisBackgroundScaled, setAxisBackgroundScaledMode)
- - Added width and height parameter on PDF export function QCustomPlot::savePdf(). This now allows PDF export to
- have arbitrary dimensions, independent of the current geometry of the QCustomPlot.
- - Added overload of QCustomPlot::removeGraph that takes QCustomPlotGraph* as parameter, instead the index of the graph
- - Added all enums to the Qt meta system via Q_ENUMS(). The enums can now be transformed
- to QString values easily with the Qt meta system, which makes saving state e.g. as XML
- significantly nicer.
- - added typedef QMapIterator<double,QCustomPlotData> QCustomPlotDataMapIterator
- and typedef QMutableMapIterator<double,QCustomPlotData> QCustomPlotDataMutableMapIterator
- for improved information hiding, when using iterators outside QCustomPlot code
-
- Bugfixes:
- - Fixed savePngScaled. Axis/label drawing functions used to reset the painter transform
- and thereby break savePngScaled. Now they buffer the current transform and restore it afterwards.
- - Fixed some glitches in the doxygen comments (affects documentation only)
-
- Other:
- - Changed the default tickLabelPadding of top axis from 3 to 6 pixels. Looks better.
- - Changed the default QCustomPlot::setAntialiasedElements setting: Graph fills are now antialiased
- by default. That's a bit slower, but makes fill borders look better.
-
-#### Version released on 19.11.11 ####
-
- Changes that break backward compatibility:
- - QCustomPlotAxis: tickFont and setTickFont renamed to tickLabelFont and setTickLabelFont (for naming consistency)
-
- Other:
- - QCustomPlotAxis: Added rotated tick labels, see setTickLabelRotation
