Detailed Description

The abstract base class for all data representing objects in a plot.

It defines a very basic interface like name, pen, brush, visibility etc. Since this class is abstract, it can't be instantiated. Use one of the subclasses or create a subclass yourself to create new ways of displaying data (see "Creating own plottables" below). Plottables that display one-dimensional data (i.e. data points have a single key dimension and one or multiple values at each key) are based off of the template subclass QCPAbstractPlottable1D, see details there.

All further specifics are in the subclasses, for example:

A normal graph with possibly a line and/or scatter points QCPGraph (typically created with QCustomPlot::addGraph)
A parametric curve: QCPCurve
A bar chart: QCPBars
A statistical box plot: QCPStatisticalBox
A color encoded two-dimensional map: QCPColorMap
An OHLC/Candlestick chart: QCPFinancial

Creating own plottables

Subclassing directly from QCPAbstractPlottable is only recommended if you wish to display two-dimensional data like QCPColorMap, i.e. two logical key dimensions and one (or more) data dimensions. If you want to display data with only one logical key dimension, you should rather derive from QCPAbstractPlottable1D.

If subclassing QCPAbstractPlottable directly, these are the pure virtual functions you must implement:

See the documentation of those functions for what they need to do.

For drawing your plot, you can use the coordsToPixels functions to translate a point in plot coordinates to pixel coordinates. This function is quite convenient, because it takes the orientation of the key and value axes into account for you (x and y are swapped when the key axis is vertical and the value axis horizontal). If you are worried about performance (i.e. you need to translate many points in a loop like QCPGraph), you can directly use QCPAxis::coordToPixel. However, you must then take care about the orientation of the axis yourself.

Here are some important members you inherit from QCPAbstractPlottable:

QCustomPlot *mParentPlot	A pointer to the parent QCustomPlot instance. The parent plot is inferred from the axes that are passed in the constructor.
QString mName	The name of the plottable.
QPen mPen	The generic pen of the plottable. You should use this pen for the most prominent data representing lines in the plottable (e.g QCPGraph uses this pen for its graph lines and scatters)
QBrush mBrush	The generic brush of the plottable. You should use this brush for the most prominent fillable structures in the plottable (e.g. QCPGraph uses this brush to control filling under the graph)
QPointer<QCPAxis> mKeyAxis, mValueAxis	The key and value axes this plottable is attached to. Call their QCPAxis::coordToPixel functions to translate coordinates to pixels in either the key or value dimension. Make sure to check whether the pointer is null before using it. If one of the axes is null, don't draw the plottable.
QCPSelectionDecorator mSelectionDecorator	The currently set selection decorator which specifies how selected data of the plottable shall be drawn and decorated. When drawing your data, you must consult this decorator for the appropriate pen/brush before drawing unselected/selected data segments. Finally, you should call its QCPSelectionDecorator::drawDecoration method at the end of your draw implementation.
QCP::SelectionType mSelectable	In which composition, if at all, this plottable's data may be selected. Enforcing this setting on the data selection is done by QCPAbstractPlottable automatically.
QCPDataSelection mSelection	Holds the current selection state of the plottable's data, i.e. the selected data ranges (QCPDataRange).

It defines a very basic interface like name, pen, brush, visibility etc. Since this class is abstract, it can't be instantiated. Use one of the subclasses or create a subclass yourself to create new ways of displaying data (see "Creating own plottables" below).

All further specifics are in the subclasses, for example:

A normal graph with possibly a line, scatter points and error bars: QCPGraph (typically created with QCustomPlot::addGraph)
A parametric curve: QCPCurve
A bar chart: QCPBars
A statistical box plot: QCPStatisticalBox
A color encoded two-dimensional map: QCPColorMap
An OHLC/Candlestick chart: QCPFinancial

Creating own plottables

To create an own plottable, you implement a subclass of QCPAbstractPlottable. These are the pure virtual functions, you must implement:

See the documentation of those functions for what they need to do.

For drawing your plot, you can use the coordsToPixels functions to translate a point in plot coordinates to pixel coordinates. This function is quite convenient, because it takes the orientation of the key and value axes into account for you (x and y are swapped when the key axis is vertical and the value axis horizontal). If you are worried about performance (i.e. you need to translate many points in a loop like QCPGraph), you can directly use QCPAxis::coordToPixel. However, you must then take care about the orientation of the axis yourself.

Here are some important members you inherit from QCPAbstractPlottable:

QCustomPlot *mParentPlot	A pointer to the parent QCustomPlot instance. The parent plot is inferred from the axes that are passed in the constructor.
QString mName	The name of the plottable.
QPen mPen	The generic pen of the plottable. You should use this pen for the most prominent data representing lines in the plottable (e.g QCPGraph uses this pen for its graph lines and scatters)
QPen mSelectedPen	The generic pen that should be used when the plottable is selected (hint: mainPen gives you the right pen, depending on selection state).
QBrush mBrush	The generic brush of the plottable. You should use this brush for the most prominent fillable structures in the plottable (e.g. QCPGraph uses this brush to control filling under the graph)
QBrush mSelectedBrush	The generic brush that should be used when the plottable is selected (hint: mainBrush gives you the right brush, depending on selection state).
QPointer<QCPAxis>mKeyAxis, mValueAxis	The key and value axes this plottable is attached to. Call their QCPAxis::coordToPixel functions to translate coordinates to pixels in either the key or value dimension. Make sure to check whether the pointer is null before using it. If one of the axes is null, don't draw the plottable.
bool mSelected	indicates whether the plottable is selected or not.

Constructor & Destructor Documentation

◆ QCPAbstractPlottable() [1/2]

QCPAbstractPlottable::QCPAbstractPlottable	(	QCPAxis *	keyAxis,
		QCPAxis *	valueAxis
	)

Constructs an abstract plottable 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 have perpendicular orientations. If either of these restrictions is violated, a corresponding message is printed to the debug output (qDebug), the construction is not aborted, though.

Since QCPAbstractPlottable is an abstract class that defines the basic interface to plottables, it can't be directly instantiated.

You probably want one of the subclasses like QCPGraph or QCPCurve instead.

Member Function Documentation

◆ addToLegend() [1/3]

bool QCPAbstractPlottable::addToLegend ( )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Adds this plottable to the legend of the parent QCustomPlot (QCustomPlot::legend).

See also: removeFromLegend

Adds this plottable to the legend of the parent QCustomPlot (QCustomPlot::legend).

Normally, a QCPPlottableLegendItem is created and inserted into the legend. If the plottable needs a more specialized representation in the legend, this function will take this into account and instead create the specialized subclass of QCPAbstractLegendItem.

Returns true on success, i.e. when the legend exists and a legend item associated with this plottable isn't already in the legend.

◆ addToLegend() [3/3]

bool QCPAbstractPlottable::addToLegend ( QCPLegend * legend )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Adds this plottable to the specified legend.

Creates a QCPPlottableLegendItem which is inserted into the legend. Returns true on success, i.e. when the legend exists and a legend item associated with this plottable isn't already in the legend.

If the plottable needs a more specialized representation in the legend, you can create a corresponding subclass of QCPPlottableLegendItem and add it to the legend manually instead of calling this method.

◆ getKeyRange() [1/2]

QCPRange QCPAbstractPlottable::getKeyRange	(	bool &	foundRange,

pure virtual

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.

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.

◆ getValueRange() [2/2]

QCPRange QCPAbstractPlottable::getValueRange	(	bool &	foundRange,

	)		const

protectedpure virtual

called by rescaleAxes functions to get the full data value bounds. For logarithmic plots, one can set inSignDomain to either sdNegative or sdPositive in order to restrict the returned range to that sign domain. E.g. when only negative range is wanted, set inSignDomain to sdNegative and all positive points will be ignored for range calculation. For no restriction, just set inSignDomain to 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, which wouldn't count as a valid range.

If this plottable is a one-dimensional plottable, i.e. it implements the QCPPlottableInterface1D, returns the this pointer with that type. Otherwise (e.g. in the case of a QCPColorMap) returns zero.

You can use this method to gain read access to data coordinates while holding a pointer to the abstract base class only.

◆ rescaleAxes() [1/2]

void QCPAbstractPlottable::rescaleAxes ( bool onlyEnlarge = false ) const

Rescales the key and value axes associated with this plottable to contain all displayed data, so the whole plottable is visible. If the scaling of an axis is logarithmic, rescaleAxes will make sure not to rescale to an illegal range i.e. a range containing different signs and/or zero. Instead it will stay in the current sign domain and ignore all parts of the plottable that lie outside of that domain.

onlyEnlarge makes sure the ranges are only expanded, never reduced. So it's possible to show multiple plottables in their entirety by multiple calls to rescaleAxes where the first call has onlyEnlarge set to false (the default), and all subsequent set to true.

virtual double QCPAbstractPlottable::selectTest	(	const QPointF &	pos,

	)		const

This function is used to decide whether a click hits a layerable object or not.

pos is a point in pixel coordinates on the QCustomPlot surface. This function returns the shortest pixel distance of this point to the object. If the object is either invisible or the distance couldn't be determined, -1.0 is returned. Further, if onlySelectable is true and the object is not selectable, -1.0 is returned, too.

If the object is represented not by single lines but by an area like a QCPItemText or the bars of a QCPBars plottable, a click inside the area should also be considered a hit. In these cases this function thus returns a constant value greater zero but still below the parent plot's selection tolerance. (typically the selectionTolerance multiplied by 0.99).

Providing a constant value for area objects allows selecting line objects even when they are obscured by such area objects, by clicking close to the lines (i.e. closer than 0.99*selectionTolerance).

The actual setting of the selection state is not done by this function. This is handled by the parent QCustomPlot when the mouseReleaseEvent occurs, and the finally selected object is notified via the selectEvent/ deselectEvent methods.

details is an optional output parameter. Every layerable subclass may place any information in details. This information will be passed to selectEvent when the parent QCustomPlot decides on the basis of this selectTest call, that the object was successfully selected. The subsequent call to selectEvent will carry the details. This is useful for multi-part objects (like QCPAxis). This way, a possibly complex calculation to decide which part was clicked is only done once in selectTest. The result (i.e. the actually clicked part) can then be placed in details. So in the subsequent selectEvent, the decision which part was selected doesn't have to be done a second time for a single selection operation.

In the case of 1D Plottables (QCPAbstractPlottable1D, like QCPGraph or QCPBars) details will be set to a QCPDataSelection, describing the closest data point to pos.

You may pass 0 as details to indicate that you are not interested in those selection details.

The key axis of a plottable can be set to any axis of a QCustomPlot, as long as it is orthogonal to the plottable's value axis. This function performs no checks to make sure this is the case. The typical mathematical choice is to use the x-axis (QCustomPlot::xAxis) as key axis and the y-axis (QCustomPlot::yAxis) as value axis.

Normally, the key and value axes are set in the constructor of the plottable (or QCustomPlot::addGraph when working with QCPGraphs through the dedicated graph interface).

◆ setPen() [1/2]

void QCPAbstractPlottable::setPen ( const QPen & pen )

The pen is used to draw basic lines that make up the plottable representation in the plot.

For example, the QCPGraph subclass draws its graph lines with this pen.

◆ setSelectable() [1/2]

void QCPAbstractPlottable::setSelectable ( bool selectable )

Sets whether the user can (de-)select this plottable by clicking on the QCustomPlot surface. (When QCustomPlot::setInteractions contains iSelectPlottables.)

However, even when selectable was set to false, it is possible to set the selection manually, by calling setSelected directly.

◆ setSelectable() [2/2]

void QCPAbstractPlottable::setSelectable ( QCP::SelectionType selectable )

Sets whether and to which granularity this plottable can be selected.

A selection can happen by clicking on the QCustomPlot surface (When QCustomPlot::setInteractions contains QCP::iSelectPlottables), by dragging a selection rect (When QCustomPlot::setSelectionRectMode is QCP::srmSelect), or programmatically by calling setSelection.

◆ setSelected()

void QCPAbstractPlottable::setSelected ( bool selected )

Sets whether this plottable is selected or not. When selected, it uses a different pen and brush to draw its lines and fills, see setSelectedPen and setSelectedBrush.

The entire selection mechanism for plottables is handled automatically when QCustomPlot::setInteractions contains iSelectPlottables. You only need to call this function when you wish to change the selection state manually.

This function can change the selection state even when setSelectable was set to false.

emits the selectionChanged signal when selected is different from the previous selection state.

◆ setSelectedBrush()

void QCPAbstractPlottable::setSelectedBrush ( const QBrush & brush )

When the plottable is selected, this brush is used to draw fills instead of the normal brush set via setBrush.

◆ setSelection()

void QCPAbstractPlottable::setSelection ( QCPDataSelection selection )

Sets which data ranges of this plottable are selected. Selected data ranges are drawn differently (e.g. color) in the plot. This can be controlled via the selection decorator (see selectionDecorator).

The entire selection mechanism for plottables is handled automatically when QCustomPlot::setInteractions contains iSelectPlottables. You only need to call this function when you wish to change the selection state programmatically.

Using setSelectable you can further specify for each plottable whether and to which granularity it is selectable. If selection is not compatible with the current QCP::SelectionType set via setSelectable, the resulting selection will be adjusted accordingly (see QCPDataSelection::enforceType).

emits the selectionChanged signal when selected is different from the previous selection state.

◆ setSelectionDecorator()

void QCPAbstractPlottable::setSelectionDecorator ( QCPSelectionDecorator * decorator )

Use this method to set an own QCPSelectionDecorator (subclass) instance. This allows you to customize the visual representation of selected data ranges further than by using the default QCPSelectionDecorator.

The plottable takes ownership of the decorator.

The currently set decorator can be accessed via selectionDecorator.

◆ setValueAxis() [1/2]

void QCPAbstractPlottable::setValueAxis ( QCPAxis * axis )

The value axis of a plottable can be set to any axis of a QCustomPlot, as long as it is orthogonal to the plottable's key axis. This function performs no checks to make sure this is the case. The typical mathematical choice is to use the x-axis (QCustomPlot::xAxis) as key axis and the y-axis (QCustomPlot::yAxis) as value axis.

Normally, the key and value axes are set in the constructor of the plottable (or QCustomPlot::addGraph when working with QCPGraphs through the dedicated graph interface).
