Detailed Description
A plottable representing a bar chart in a plot.
To plot data, assign it with the setData or addData functions.
Changing the appearance
The appearance of the bars is determined by the pen and the brush (setPen, setBrush). The width of the individual bars can be controlled with setWidthType and setWidth.
Bar charts are stackable. This means, two QCPBars plottables can be placed on top of each other (see QCPBars::moveAbove). So when two bars are at the same key position, they will appear stacked.
If you would like to group multiple QCPBars plottables together so they appear side by side as shown below, use QCPBarsGroup.
Usage
Like all data representing objects in QCustomPlot, the QCPBars is a plottable (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
Usually, you first create an instance:
which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead. The newly created plottable can be modified, e.g.:

Member Enumeration Documentation
◆ WidthType
enum QCPBars::WidthType |
Defines the ways the width of the bar can be specified. Thus it defines what the number passed to setWidth actually means.
- See also
- setWidthType, setWidth
Definition at line 5832 of file qcustomplot.h.
Constructor & Destructor Documentation
◆ QCPBars()
Constructs a bar chart which uses keyAxis as its key axis ("x") and valueAxis as its value axis ("y"). keyAxis and valueAxis must reside in the same QCustomPlot instance and not have the same orientation. If either of these restrictions is violated, a corresponding message is printed to the debug output (qDebug), the construction is not aborted, though.
The created QCPBars is automatically registered with the QCustomPlot instance inferred from keyAxis. This QCustomPlot instance takes ownership of the QCPBars, so do not delete it manually but use QCustomPlot::removePlottable() instead.

Member Function Documentation
◆ addData() [1/2]
void QCPBars::addData | ( | const QVector< double > & | keys, |
const QVector< double > & | values, | ||
bool | alreadySorted = false ) |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
Adds the provided points in keys and values to the current data. The provided vectors should have equal length. Else, the number of added points will be the size of the smallest vector.
If you can guarantee that the passed data points are sorted by keys in ascending order, you can set alreadySorted to true, to improve performance by saving a sorting run.
Alternatively, you can also access and modify the data directly via the data method, which returns a pointer to the internal data container.
Definition at line 24585 of file qcustomplot.cpp.
◆ addData() [2/2]
void QCPBars::addData | ( | double | key, |
double | value ) |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Adds the provided data point as key and value to the current data.
Alternatively, you can also access and modify the data directly via the data method, which returns a pointer to the internal data container.
Definition at line 24610 of file qcustomplot.cpp.
◆ barAbove()
|
inline |
Returns the bars plottable that is directly above this bars plottable. If there is no such plottable, returns nullptr
.
Definition at line 5848 of file qcustomplot.h.
◆ barBelow()
|
inline |
Returns the bars plottable that is directly below this bars plottable. If there is no such plottable, returns nullptr
.
Definition at line 5847 of file qcustomplot.h.
◆ barsGroup()
|
inline |
Definition at line 5844 of file qcustomplot.h.
◆ baseValue()
|
inline |
Definition at line 5845 of file qcustomplot.h.
◆ connectBars()
Connects below and above to each other via their mBarAbove/mBarBelow properties. The bar(s) currently above lower and below upper will become disconnected to lower/upper.
If lower is zero, upper will be disconnected at the bottom. If upper is zero, lower will be disconnected at the top.
Definition at line 25100 of file qcustomplot.cpp.
◆ data()
|
inline |
Returns a shared pointer to the internal data storage of type QCPBarsDataContainer. You may use it to directly manipulate the data, which may be more convenient and faster than using the regular setData or addData methods.
Definition at line 5849 of file qcustomplot.h.
◆ dataPixelPosition()
|
overridevirtual |
Returns the pixel position on the widget surface at which the data point at the given index appears.
Usually this corresponds to the point of dataMainKey/ dataMainValue, in pixel coordinates. However, depending on the plottable, this might be a different apparent position than just a coord-to-pixel transform of those values. For example, QCPBars apparent data values can be shifted depending on their stacking, bar grouping or configured base value.
Reimplemented from QCPAbstractPlottable1D< QCPBarsData >.
Definition at line 24821 of file qcustomplot.cpp.
◆ draw()
|
overrideprotectedvirtual |
This function draws the layerable with the specified painter. It is only called by QCustomPlot, if the layerable is visible (setVisible).
Before this function is called, the painter's antialiasing state is set via applyDefaultAntialiasingHint, see the documentation there. Further, the clipping rectangle was set to clipRect.
Implements QCPAbstractPlottable.
Definition at line 24844 of file qcustomplot.cpp.
◆ drawLegendIcon()
|
overrideprotectedvirtual |
called by QCPLegend::draw (via QCPPlottableLegendItem::draw) to create a graphical representation of this plottable inside rect, next to the plottable name.
The passed painter has its cliprect set to rect, so painting outside of rect won't appear outside the legend icon border.
Implements QCPAbstractPlottable.
Definition at line 24893 of file qcustomplot.cpp.
◆ getBarRect()
|
protected |
Returns the rect in pixel coordinates of a single bar with the specified key and value. The rect is shifted according to the bar stacking (see moveAbove) and base value (see setBaseValue), and to have non-overlapping border lines with the bars stacked below.
Definition at line 24978 of file qcustomplot.cpp.
◆ getKeyRange()
|
overridevirtual |
Returns the coordinate range that all data in this plottable span in the key axis dimension. For logarithmic plots, one can set inSignDomain to either QCP::sdNegative or QCP::sdPositive in order to restrict the returned range to that sign domain. E.g. when only negative range is wanted, set inSignDomain to QCP::sdNegative and all positive points will be ignored for range calculation. For no restriction, just set inSignDomain to QCP::sdBoth (default). foundRange is an output parameter that indicates whether a range could be found or not. If this is false, you shouldn't use the returned range (e.g. no points in data).
Note that foundRange is not the same as QCPRange::validRange, since the range returned by this function may have size zero (e.g. when there is only one data point). In this case foundRange would return true, but the returned range is not a valid range in terms of QCPRange::validRange.

- rescaleAxes, getValueRange
Implements QCPAbstractPlottable.
Definition at line 24742 of file qcustomplot.cpp.
◆ getPixelWidth()
|
protected |
This function is used to determine the width of the bar at coordinate key, according to the specified width (setWidth) and width type (setWidthType).
The output parameters lower and upper return the number of pixels the bar extends to lower and higher keys, relative to the key coordinate (so with a non-reversed horizontal axis, lower is negative and upper positive).
Definition at line 25015 of file qcustomplot.cpp.
◆ getStackedBaseValue()
|
protected |
This function is called to find at which value to start drawing the base of a bar at key, when it is stacked on top of another QCPBars (e.g. with moveAbove).
positive and negative bars are separated per stack (positive are stacked above baseValue upwards, negative are stacked below baseValue downwards). This can be indicated with positive. So if the bar for which we need the base value is negative, set positive to false.
Definition at line 25065 of file qcustomplot.cpp.
◆ getValueRange()
|
overridevirtual |
Returns the coordinate range that the data points in the specified key range (inKeyRange) span in the value axis dimension. For logarithmic plots, one can set inSignDomain to either QCP::sdNegative or QCP::sdPositive in order to restrict the returned range to that sign domain. E.g. when only negative range is wanted, set inSignDomain to QCP::sdNegative and all positive points will be ignored for range calculation. For no restriction, just set inSignDomain to QCP::sdBoth (default). foundRange is an output parameter that indicates whether a range could be found or not. If this is false, you shouldn't use the returned range (e.g. no points in data).
If inKeyRange has both lower and upper bound set to zero (is equal to QCPRange()
), all data points are considered, without any restriction on the keys.
Note that foundRange is not the same as QCPRange::validRange, since the range returned by this function may have size zero (e.g. when there is only one data point). In this case foundRange would return true, but the returned range is not a valid range in terms of QCPRange::validRange.
- See also
- rescaleAxes, getKeyRange
Implements QCPAbstractPlottable.
Definition at line 24781 of file qcustomplot.cpp.
◆ getVisibleDataBounds()
|
protected |
called by draw to determine which data (key) range is visible at the current key axis range setting, so only that needs to be processed. It also takes into account the bar width.
begin returns an iterator to the lowest data point that needs to be taken into account when plotting. Note that in order to get a clean plot all the way to the edge of the axis rect, lower may still be just outside the visible range.
end returns an iterator one higher than the highest visible data point. Same as before, end may also lie just outside of the visible range.
if the plottable contains no data, both begin and end point to constEnd.
Definition at line 24918 of file qcustomplot.cpp.
◆ moveAbove()
void QCPBars::moveAbove | ( | QCPBars * | bars | ) |
Moves this bars plottable above bars. In other words, the bars of this plottable will appear above the bars of bars. The move target bars must use the same key and value axis as this plottable.
Inserting into and removing from existing bar stacking is handled gracefully. If bars already has a bars object above itself, this bars object is inserted between the two. If this bars object is already between two other bars, the two other bars will be stacked on top of each other after the operation.
To remove this bars plottable from any stacking, set bars to nullptr
.
Definition at line 24662 of file qcustomplot.cpp.
◆ moveBelow()
void QCPBars::moveBelow | ( | QCPBars * | bars | ) |
Moves this bars plottable below bars. In other words, the bars of this plottable will appear below the bars of bars. The move target bars must use the same key and value axis as this plottable.
Inserting into and removing from existing bar stacking is handled gracefully. If bars already has a bars object below itself, this bars object is inserted between the two. If this bars object is already between two other bars, the two other bars will be stacked on top of each other after the operation.
To remove this bars plottable from any stacking, set bars to nullptr
.
Definition at line 24629 of file qcustomplot.cpp.
◆ selectTest()
|
overridevirtual |
Implements a selectTest specific to this plottable's point geometry.
If details is not 0, it will be set to a QCPDataSelection, describing the closest data point to pos.
\seebaseclassmethod QCPAbstractPlottable::selectTest
Reimplemented from QCPAbstractPlottable1D< QCPBarsData >.
Definition at line 24712 of file qcustomplot.cpp.
◆ selectTestRect()
|
overridevirtual |
Returns a data selection containing all the data points of this plottable which are contained (or hit by) rect. This is used mainly in the selection rect interaction for data selection (data selection mechanism).
If onlySelectable is true, an empty QCPDataSelection is returned if this plottable is not selectable (i.e. if QCPAbstractPlottable::setSelectable is QCP::stNone).
- Note
- rect must be a normalized rect (positive or zero width and height). This is especially important when using the rect of QCPSelectionRect::accepted, which is not necessarily normalized. Use
QRect::normalized()
when passing a rect which might not be normalized.
Reimplemented from QCPAbstractPlottable1D< QCPBarsData >.
Definition at line 24684 of file qcustomplot.cpp.
◆ setBarsGroup()
void QCPBars::setBarsGroup | ( | QCPBarsGroup * | barsGroup | ) |
Sets to which QCPBarsGroup this QCPBars instance belongs to. Alternatively, you can also use QCPBarsGroup::append.
To remove this QCPBars from any group, set barsGroup to nullptr
.
Definition at line 24535 of file qcustomplot.cpp.
◆ setBaseValue()
void QCPBars::setBaseValue | ( | double | baseValue | ) |
Sets the base value of this bars plottable.
The base value defines where on the value coordinate the bars start. How far the bars extend from the base value is given by their individual value data. For example, if the base value is set to 1, a bar with data value 2 will have its lowest point at value coordinate 1 and highest point at 3.
For stacked bars, only the base value of the bottom-most QCPBars has meaning.
The default base value is 0.
Definition at line 24558 of file qcustomplot.cpp.
◆ setData() [1/2]
void QCPBars::setData | ( | const QVector< double > & | keys, |
const QVector< double > & | values, | ||
bool | alreadySorted = false ) |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
Replaces the current data with the provided points in keys and values. The provided vectors should have equal length. Else, the number of added points will be the size of the smallest vector.
If you can guarantee that the passed data points are sorted by keys in ascending order, you can set alreadySorted to true, to improve performance by saving a sorting run.

- addData
Definition at line 24499 of file qcustomplot.cpp.
◆ setData() [2/2]
void QCPBars::setData | ( | QSharedPointer< QCPBarsDataContainer > | data | ) |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
Replaces the current data container with the provided data container.
Since a QSharedPointer is used, multiple QCPBars may share the same data container safely. Modifying the data in the container will then affect all bars that share the container. Sharing can be achieved by simply exchanging the data containers wrapped in shared pointers:
If you do not wish to share containers, but create a copy from an existing container, rather use the QCPDataContainer<DataType>::set method on the bar's data container directly:

- addData
Definition at line 24483 of file qcustomplot.cpp.
◆ setStackingGap()
void QCPBars::setStackingGap | ( | double | pixels | ) |
If this bars plottable is stacked on top of another bars plottable (moveAbove), this method allows specifying a distance in pixels, by which the drawn bar rectangles will be separated by the bars below it.
Definition at line 24568 of file qcustomplot.cpp.
◆ setWidth()
void QCPBars::setWidth | ( | double | width | ) |
Sets the width of the bars.
How the number passed as width is interpreted (e.g. screen pixels, plot coordinates,...), depends on the currently set width type, see setWidthType and WidthType.
Definition at line 24511 of file qcustomplot.cpp.
◆ setWidthType()
void QCPBars::setWidthType | ( | QCPBars::WidthType | widthType | ) |
Sets how the width of the bars is defined. See the documentation of WidthType for an explanation of the possible values for widthType.
The default value is wtPlotCoords.
