- New QCPCurve optimization algorithm, fixes bug which caused line flicker at deep zoom into curve segment | ||||
- Item positions can now have different position types and anchors for their x and y coordinates (QCPItemPosition::setTypeX/Y, setParentAnchorX/Y) | ||||
- QCPGraph and QCPCurve can now display gaps in their lines, when inserting quiet NaNs as values (std::numeric_limits<double>::quiet_NaN()) | ||||
- QCPAxis now supports placing the tick labels inside the axis rect, for particularly space saving plots (QCPAxis::setTickLabelSide) | ||||
Added features after beta: | ||||

- 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 | ||||
Bugfixes after beta: | ||||
- Fixed bug of QCPColorMap/QCPColorGradient colors being off by one color sampling step (only noticeable in special cases) | ||||
- Fixed bug of QCPGraph adaptive sampling on vertical key axis, causing staggered look | ||||
- Fixed low (float) precision in QCPCurve optimization algorithm, by not using QVector2D anymore | ||||
Other: | ||||
- Qt 5.3 and Qt 5.4 compatibility | ||||
#### Version 1.2.1 released on 07.04.14 #### | ||||
Bugfixes: | ||||
- Fixed regression which garbled date-time tick labels on axes, if setTickLabelType is ltDateTime and setNumberFormat contains the "b" option | ||||
#### Version 1.2.0 released on 14.03.14 #### | ||||
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 | ||||
- added notification signal QCPLayerable::layerChanged | ||||
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 | ||||
- Added missing Q_PROPERTY for QCPAxis::setDateTimeSpec | ||||
- Fixed behaviour of QCPAxisRect::setupFullAxesBox (now transfers more properties from bottom/left to top/right axes and sets visibility of bottom/left axes to true) | ||||
- Made sure PDF export doesn't default to grayscale output on some systems | ||||
Other: | ||||
- Plotting hint QCP::phForceRepaint is now enabled on all systems (and not only on windows) by default | ||||
- Documentation improvements | ||||
#### Version 1.1.0 released on 04.11.13 #### | ||||
Added features: | ||||
- Added QCPRange::expand and QCPRange::expanded | ||||
- Added QCPAxis::rescale to rescale axis to all associated plottables | ||||
- Added QCPAxis::setDateTimeSpec/dateTimeSpec to allow axis labels either in UTC or local time | ||||
- QCPAxis now additionally emits a rangeChanged signal overload that provides the old range as second parameter | ||||
Bugfixes: | ||||
- Fixed QCustomPlot::rescaleAxes not rescaling properly if first plottable has an empty range | ||||
- 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 | ||||
- 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 | ||||
