signal |
This signal is emitted when the QCustomPlot receives a mouse wheel event.
It is emitted before QCustomPlot handles any other mechanisms like range zooming. So a slot connected to this signal can still influence the behaviour e.g. with QCPAxisRect::setRangeZoom, QCPAxisRect::setRangeZoomAxes or QCPAxisRect::setRangeZoomFactor.
bool QCustomPlot::moveLayer | ( | QCPLayer * | layer, |
QCPLayer * | otherLayer, | ||
QCustomPlot::LayerInsertMode | insertMode = limAbove |
||
) |
Moves the specified layer either above or below otherLayer.
Whether it's placed above or below is controlled with insertMode.
Returns true on success, i.e. when both layer and otherLayer are valid layers in the QCustomPlot.

Returns the plottable at the pixel position pos.
Plottables that only consist of single lines (like graphs) have a tolerance band around them, see setSelectionTolerance. If multiple plottables come into consideration, the one closest to pos is returned.
If onlySelectable is true, only plottables that are selectable (QCPAbstractPlottable::setSelectable) are considered.
If there is no plottable at pos, the return value is 0.

bool QCustomPlot::removeGraph | ( | QCPGraph * | graph | ) |
Removes the specified graph from the plot and, if necessary, from the QCustomPlot::legend.
If any other graphs in the plot have a channel fill set towards the removed graph, the channel fill property of those graphs is reset to zero (no channel fill).
Returns true on success.

bool QCustomPlot::removeLayer | ( | QCPLayer * | layer | ) |
Removes the specified layer and returns true on success.
All layerables (e.g. plottables and items) on the removed layer will be moved to the layer below layer. If layer is the bottom layer, the layerables are moved to the layer above. In both cases, the total rendering order of all layerables in the QCustomPlot is preserved.
If layer is the current layer (setCurrentLayer), the layer below (or above, if bottom layer) becomes the new current layer.
It is not possible to remove the last layer of the plot.

void QCustomPlot::replot | ( | QCustomPlot::RefreshPriority | refreshPriority = QCustomPlot::rpHint | ) |
Causes a complete replot into the internal buffer.
Finally, update() is called, to redraw the buffer on the QCustomPlot widget surface. This is the method that must be called to make changes, for example on the axis ranges or data points of graphs, visible.
Under a few circumstances, QCustomPlot causes a replot by itself. Those are resize events of the QCustomPlot widget and user interactions (object selection and range dragging/zooming).
Before the replot happens, the signal beforeReplot is emitted. After the replot, afterReplot is emitted. It is safe to mutually connect the replot slot with any of those two signals on two QCustomPlots to make them replot synchronously, it won't cause an infinite recursion.
Definition at line 10417 of file qcustomplot.cpp.
void QCustomPlot::rescaleAxes | ( | bool | onlyVisiblePlottables = false | ) |
Rescales the axes such that all plottables (like graphs) in the plot are fully visible.

bool QCustomPlot::saveBmp | ( | const QString & | fileName, |
int | width = 0 , |
||
int | height = 0 , |
||
double | scale = 1.0 |
||
) |
Saves a BMP image file to fileName on disc.
The output plot will have the dimensions width and height in pixels. If either width or height is zero, the exported image will have the same dimensions as the QCustomPlot widget currently has. Line widths and texts etc. are not scaled up when larger widths/heights are used. If you want that effect, use the scale parameter.
For example, if you set both width and height to 100 and scale to 2, you will end up with an image file of size 200*200 in which all graphical elements are scaled up by factor 2 (line widths, texts, etc.). This scaling is not done by stretching a 100*100 image, the result will have full 200*200 pixel resolution.
If you use a high scaling factor, it is recommended to enable antialiasing for all elements via temporarily setting QCustomPlot::setAntialiasedElements to QCP::aeAll as this allows QCustomPlot to place objects with sub-pixel accuracy.
The objects of the plot will appear in the current selection state. If you don't want any selected objects to be painted in their selected look, deselect everything with deselectAll before calling this function.
Returns true on success. If this function fails, most likely the BMP format isn't supported by the system, see Qt docs about QImageWriter::supportedImageFormats().

Saves a PDF with the vectorized plot to the file fileName.
The axis ratio as well as the scale of texts and lines will be derived from the specified width and height. This means, the output will look like the normal on-screen output of a QCustomPlot widget with the corresponding pixel width and height. If either width or height is zero, the exported image will have the same dimensions as the QCustomPlot widget currently has.
noCosmeticPen disables the use of cosmetic pens when drawing to the PDF file. Cosmetic pens are pens with numerical width 0, which are always drawn as a one pixel wide line, no matter what zoom factor is set in the PDF-Viewer. For more information about cosmetic pens, see the QPainter and QPen documentation.
The objects of the plot will appear in the current selection state. If you don't want any selected objects to be painted in their selected look, deselect everything with deselectAll before calling this function.
Returns true on success.

If you want the PNG to have a transparent background, call setBackground(const QBrush &brush) with no brush (Qt::NoBrush) or a transparent color (Qt::transparent), before saving.
PNG compression can be controlled with the quality parameter which must be between 0 and 100 or -1 to use the default setting.
Returns true on success. If this function fails, most likely the PNG format isn't supported by the system, see Qt docs about QImageWriter::supportedImageFormats().

Saves the plot to a rastered image file fileName in the image format format.
The plot is sized to width and height in pixels and scaled with scale. (width 100 and scale 2.0 lead to a full resolution file with width 200.) If the format supports compression, quality may be between 0 and 100 to control it.

signal |
This signal is emitted after the user has changed the selection in the QCustomPlot, e.g.
by clicking. It is not emitted when the selection state of an object has changed programmatically by a direct call to setSelected() on an object or by calling deselectAll.
In addition to this signal, selectable objects also provide individual signals, for example QCPAxis::selectionChanged or QCPAbstractPlottable::selectionChanged. Note that those signals are emitted even if the selection state is changed programmatically.
See the documentation of setInteractions for details about the selection mechanism.

void QCustomPlot::setAntialiasedElement | ( | QCP::AntialiasedElement | antialiasedElement, |

See setAntialiasedElements for details.
Definition at line 9193 of file qcustomplot.cpp.
void QCustomPlot::setAntialiasedElements | ( | const QCP::AntialiasedElements & | antialiasedElements | ) |
Sets which elements are forcibly drawn antialiased as an or combination of QCP::AntialiasedElement.
This overrides the antialiasing settings for whole element groups, normally controlled with the setAntialiasing function on the individual elements. If an element is neither specified in setAntialiasedElements nor in setNotAntialiasedElements, the antialiasing setting on each individual element instance is used.
For example, if antialiasedElements contains QCP::aePlottables, all plottables will be drawn antialiased, no matter what the specific QCPAbstractPlottable::setAntialiased value was set to.
if an element in antialiasedElements is already set in setNotAntialiasedElements, it is removed from there.
Definition at line 9177 of file qcustomplot.cpp.
void QCustomPlot::setAutoAddPlottableToLegend | ( | bool | on | ) |
If set to true, adding a plottable (e.g.
a graph) to the QCustomPlot automatically also adds the plottable to the legend (QCustomPlot::legend).
Definition at line 9257 of file qcustomplot.cpp.
void QCustomPlot::setBackground | ( | const QBrush & | brush | ) |
Sets the background brush of the viewport (see setViewport).
Before drawing everything else, the background is filled with brush. If a background pixmap was set with setBackground(const QPixmap &pm), this brush will be used to fill the viewport before the background pixmap is drawn. This can be useful for background pixmaps with translucent areas.
Set brush to Qt::NoBrush or Qt::Transparent to leave background transparent. This can be useful for exporting to image formats which support transparency, e.g. savePng.
Definition at line 9458 of file qcustomplot.cpp.
void QCustomPlot::setBackground | ( | const QPixmap & | pm | ) |
Sets pm as the viewport background pixmap (see setViewport).
The pixmap is always drawn below all other objects in the plot.
For cases where the provided pixmap doesn't have the same size as the viewport, scaling can be enabled with setBackgroundScaled and the scaling mode (whether and how the aspect ratio is preserved) can be set with setBackgroundScaledMode. To set all these options in one call, consider using the overloaded version of this function.
If a background brush was set with setBackground(const QBrush &brush), the viewport will first be filled with that brush, before drawing the background pixmap. This can be useful for background pixmaps with translucent areas.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.Allows setting the background pixmap of the viewport, whether it shall be scaled and how it shall be scaled in one call.
Definition at line 9470 of file qcustomplot.cpp.
void QCustomPlot::setBackgroundScaled | ( | bool | scaled | ) |
Sets whether the viewport background pixmap shall be scaled to fit the viewport.
If scaled is set to true, control whether and how the aspect ratio of the original pixmap is preserved with setBackgroundScaledMode.
Note that the scaled version of the original pixmap is buffered, so there is no performance penalty on replots. (Except when the viewport dimensions are changed continuously.)
Definition at line 9488 of file qcustomplot.cpp.
void QCustomPlot::setBackgroundScaledMode | ( | Qt::AspectRatioMode | mode | ) |
If scaling of the viewport background pixmap is enabled (setBackgroundScaled), use this function to define whether and how the aspect ratio of the original pixmap is preserved.

Sets the single interaction of this QCustomPlot to enabled.
For details about the interaction system, see setInteractions.
Definition at line 9328 of file qcustomplot.cpp.
void QCustomPlot::setInteractions | ( | const QCP::Interactions & | interactions | ) |
Sets the possible interactions of this QCustomPlot as an or-combination of QCP::Interaction enums.
There are the following types of interactions:
Axis range manipulation is controlled via QCP::iRangeDrag and QCP::iRangeZoom. When the respective interaction is enabled, the user may drag axes ranges and zoom with the mouse wheel. For details how to control which axes the user may drag/zoom and in what orientations, see QCPAxisRect::setRangeDrag, QCPAxisRect::setRangeZoom, QCPAxisRect::setRangeDragAxes, QCPAxisRect::setRangeZoomAxes.
Plottable selection is controlled by QCP::iSelectPlottables. If QCP::iSelectPlottables is set, the user may select plottables (graphs, curves, bars,...) by clicking on them or in their vicinity (setSelectionTolerance). Whether the user can actually select a plottable can further be restricted with the QCPAbstractPlottable::setSelectable function on the specific plottable. To find out whether a specific plottable is selected, call QCPAbstractPlottable::selected(). To retrieve a list of all currently selected plottables, call selectedPlottables. If you're only interested in QCPGraphs, you may use the convenience function selectedGraphs.
Item selection is controlled by QCP::iSelectItems. If QCP::iSelectItems is set, the user may select items (QCPItemLine, QCPItemText,...) by clicking on them or in their vicinity. To find out whether a specific item is selected, call QCPAbstractItem::selected(). To retrieve a list of all currently selected items, call selectedItems.
Axis selection is controlled with QCP::iSelectAxes. If QCP::iSelectAxes is set, the user may select parts of the axes by clicking on them. What parts exactly (e.g. Axis base line, tick labels, axis label) are selectable can be controlled via QCPAxis::setSelectableParts for each axis. To retrieve a list of all axes that currently contain selected parts, call selectedAxes. Which parts of an axis are selected, can be retrieved with QCPAxis::selectedParts().
Legend selection is controlled with QCP::iSelectLegend. If this is set, the user may select the legend itself or individual items by clicking on them. What parts exactly are selectable can be controlled via QCPLegend::setSelectableParts. To find out whether the legend or any of its child items are selected, check the value of QCPLegend::selectedParts. To find out which child items are selected, call QCPLegend::selectedItems.
All other selectable elements The selection of all other selectable objects (e.g. QCPPlotTitle, or your own layerable subclasses) is controlled with QCP::iSelectOther. If set, the user may select those objects by clicking on them. To find out which are currently selected, you need to check their selected state explicitly.
If the selection state has changed by user interaction, the selectionChangedByUser signal is emitted. Each selectable object additionally emits an individual selectionChanged signal whenever their selection state has changed, i.e. not only by user interaction.
To allow multiple objects to be selected by holding the selection modifier (setMultiSelectModifier), set the flag QCP::iMultiSelect.
Definition at line 9316 of file qcustomplot.cpp.
void QCustomPlot::setMultiSelectModifier | ( | Qt::KeyboardModifier | modifier | ) |
Sets the keyboard modifier that will be recognized as multi-select-modifier.
If QCP::iMultiSelect is specified in setInteractions, the user may select multiple objects by clicking on them one after the other while holding down modifier.
By default the multi-select-modifier is set to Qt::ControlModifier.
Definition at line 9405 of file qcustomplot.cpp.
void QCustomPlot::setNoAntialiasingOnDrag | ( | bool | enabled | ) |
Sets whether antialiasing is disabled for this QCustomPlot while the user is dragging axes ranges.
If many objects, especially plottables, are drawn antialiased, this greatly improves performance during dragging. Thus it creates a more responsive user experience. As soon as the user stops dragging, the last replot is done with normal antialiasing, to restore high image quality.
Definition at line 9363 of file qcustomplot.cpp.
void QCustomPlot::setNotAntialiasedElement | ( | QCP::AntialiasedElement | notAntialiasedElement, |
bool | enabled = true |
||

Sets whether the specified notAntialiasedElement is forcibly drawn not antialiased.
See setNotAntialiasedElements for details.
Definition at line 9239 of file qcustomplot.cpp.
void QCustomPlot::setNotAntialiasedElements | ( | const QCP::AntialiasedElements & | notAntialiasedElements | ) |
Sets which elements are forcibly drawn not antialiased as an or combination of QCP::AntialiasedElement.
This overrides the antialiasing settings for whole element groups, normally controlled with the setAntialiasing function on the individual elements. If an element is neither specified in setAntialiasedElements nor in setNotAntialiasedElements, the antialiasing setting on each individual element instance is used.
For example, if notAntialiasedElements contains QCP::aePlottables, no plottables will be drawn antialiased, no matter what the specific QCPAbstractPlottable::setAntialiased value was set to.
if an element in notAntialiasedElements is already set in setAntialiasedElements, it is removed from there.

Definition at line 9373 of file qcustomplot.cpp.
void QCustomPlot::setSelectionTolerance | ( | int | pixels | ) |
Sets the tolerance that is used to decide whether a click selects an object (e.g.
a plottable) or not.
If the user clicks in the vicinity of the line of e.g. a QCPGraph, it's only regarded as a potential selection when the minimum distance between the click position and the graph line is smaller than pixels. Objects that are defined by an area (e.g. QCPBars) only react to clicks directly inside the area and ignore this selection tolerance. In other words, it only has meaning for parts of objects that are too thin to exactly hit with a click and thus need such a tolerance.
Definition at line 9349 of file qcustomplot.cpp.
void QCustomPlot::setViewport | ( | const QRect & | rect | ) |
Sets the viewport of this QCustomPlot.
The Viewport is the area that the top level layout (QCustomPlot::plotLayout()) uses as its rect. Normally, the viewport is the entire widget rect.
This function is used to allow arbitrary size exports with toPixmap, savePng, savePdf, etc. by temporarily changing the viewport size.

inline |
Returns the viewport rect of this QCustomPlot instance.
The viewport is the area the plot is drawn in, all mechanisms, e.g. margin caluclation take the viewport to be the outer border of the plot. The viewport normally is the rect() of the QCustomPlot widget, i.e. a rect with top left (0, 0) and size of the QCustomPlot widget.
Don't confuse the viewport with the axis rect (QCustomPlot::axisRect). An axis rect is typically an area enclosed by four axes, where the graphs/plottables are drawn in. The viewport is larger and contains also the axes themselves, their tick numbers, their labels, the plot title etc.
Only when saving to a file (see savePng, savePdf etc.) the viewport is temporarily modified to allow saving plots with sizes independent of the current widget size.

QCPLegend * QCustomPlot::legend |
A pointer to the default legend of the main axis rect.
The legend is invisible by default. Use QCPLegend::setVisible to change this.
QCustomPlot offers convenient pointers to the axes (xAxis, yAxis, xAxis2, yAxis2) and the legend. They make it very easy working with plots that only have a single axis rect and at most one axis at each axis rect side. If you use the layout system to add multiple legends to the plot, use the layout system interface to access the new legend. For example, legends can be placed inside an axis rect's inset layout, and must then also be accessed via the inset layout. If the default legend is removed due to manipulation of the layout system (e.g. by removing the main axis rect), the corresponding pointer becomes 0.

QCPAxis * QCustomPlot::xAxis |
A pointer to the primary x Axis (bottom) of the main axis rect of the plot.
QCustomPlot offers convenient pointers to the axes (xAxis, yAxis, xAxis2, yAxis2) and the legend. They make it very easy working with plots that only have a single axis rect and at most one axis at each axis rect side. If you use the layout system to add multiple axis rects or multiple axes to one side, use the QCPAxisRect::axis interface to access the new axes. If one of the four default axes or the default legend is removed due to manipulation of the layout system (e.g. by removing the main axis rect), the corresponding pointers become 0.

QCPAxis * QCustomPlot::xAxis2 |
A pointer to the secondary x Axis (top) of the main axis rect of the plot.
Secondary axes are invisible by default. Use QCPAxis::setVisible to change this (or use QCPAxisRect::setupFullAxesBox).
