- 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 #### - - Bugfixes: - - using define flag QCUSTOMPLOT_CHECK_DATA caused debug output when data was correct, instead of invalid (fixed QCP::isInvalidData) - - documentation images are now properly shown when viewed with Qt Assistant -

- 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 -

- 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 -

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 QCustomPlotDataMapIterator - and typedef QMutableMapIterator 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 -
