Detailed Description

AbstractDiagram defines the interface for diagram classes.

AbstractDiagram is the base class for diagram classes ("chart types").

It defines the interface, that needs to be implemented for the diagram, to function within the KChart framework. It extends Interview's QAbstractItemView.

override

Definition at line 41 of file KChartAbstractDiagram.cpp.

Member Function Documentation

◆ aboutToBeDestroyed

void KChart::AbstractDiagram::aboutToBeDestroyed ( )

signal

This signal is emitted when this diagram is being destroyed, but before all the data, i.e.

the attributes model, is invalidated.

◆ allowOverlappingDataValueTexts()

bool AbstractDiagram::allowOverlappingDataValueTexts ( ) const

Returns: Whether data value labels are allowed to overlap.

Definition at line 353 of file KChartAbstractDiagram.cpp.

◆ antiAliasing()

bool AbstractDiagram::antiAliasing ( ) const

Returns: Whether anti-aliasing is to be used for rendering this diagram.

Definition at line 364 of file KChartAbstractDiagram.cpp.

◆ attributesModel()

AttributesModel * AbstractDiagram::attributesModel ( ) const

virtual

Returns the AttributesModel, that is used by this diagram.

By default each diagram owns its own AttributesModel, which should never be deleted. Only if a user-supplied AttributesModel has been set does the pointer returned here not belong to the diagram.

Returns: The AttributesModel associated with the diagram.

See also: setAttributesModel

Definition at line 187 of file KChartAbstractDiagram.cpp.

◆ attributesModelAboutToChange

void KChart::AbstractDiagram::attributesModelAboutToChange	(	KChart::AttributesModel *	newModel,
		KChart::AttributesModel *	oldModel )

signal

This signal is emitted just before the new attributes model is connected internally.

It gives you a chance to connect to its signals first or perform other setup work.

◆ attributesModelRootIndex()

QModelIndex AbstractDiagram::attributesModelRootIndex ( ) const

protected

returns a QModelIndex pointing into the AttributesModel that corresponds to the root index of the diagram.

Definition at line 212 of file KChartAbstractDiagram.cpp.

◆ boundariesChanged

void KChart::AbstractDiagram::boundariesChanged ( )

signal

Emitted upon change of a data boundary.

◆ brush() [1/3]

QBrush AbstractDiagram::brush ( ) const

Retrieve the brush to be used for painting datapoints globally.

This will fall back automatically to the default settings, if there are no specific settings.

Returns: The brush to use for painting.

Definition at line 884 of file KChartAbstractDiagram.cpp.

◆ brush() [2/3]

QBrush AbstractDiagram::brush ( const QModelIndex & index ) const

Retrieve the brush to be used, for painting the datapoint at the given index in the model.

Parameters

index The index of the datapoint in the model. With a dataset dimension of two, this is the index of the key of each key/value pair.

Returns: The brush to use for painting.

Definition at line 897 of file KChartAbstractDiagram.cpp.

◆ brush() [3/3]

QBrush AbstractDiagram::brush ( int dataset ) const

This will fall back automatically to what was set at model level, if there are no dataset specific settings.

Parameters

dataset The dataset to retrieve the brush for.

Returns: The brush to use for painting.

Definition at line 889 of file KChartAbstractDiagram.cpp.

◆ calculateDataBoundaries()

virtual const QPair< QPointF, QPointF > KChart::AbstractDiagram::calculateDataBoundaries ( ) const

Returns true if both diagrams have the same settings.

Definition at line 54 of file KChartAbstractDiagram.cpp.

◆ coordinatePlane()

AbstractCoordinatePlane * AbstractDiagram::coordinatePlane ( ) const

The coordinate plane associated with the diagram.

This determines how coordinates in value space are mapped into pixel space. By default this is a CartesianCoordinatePlane.

Returns: The coordinate plane associated with the diagram.

Definition at line 96 of file KChartAbstractDiagram.cpp.

◆ dataBoundaries()

const QPair< QPointF, QPointF > AbstractDiagram::dataBoundaries ( ) const

Return the bottom left and top right data point, that the diagram will display (unless the grid adjusts these values).

This method returns a cached result of calculations done by calculateDataBoundaries. Classes derived from AbstractDiagram must implement the calculateDataBoundaries function, to specify their own way of calculating the data boundaries. If derived classes want to force recalculation of the data boundaries, they can call setDataBoundariesDirty()

Returned value is in diagram coordinates.

Definition at line 101 of file KChartAbstractDiagram.cpp.

For example, a diagram with the default dimension of 1 will have one column per data series (the Y values) and will use automatic values for X (1, 2, 3, ... n). If the dimension is 2, the diagram will use the first, (and the third, fifth, etc) columns as X values, and the second, (and the fourth, sixth, etc) column as Y values.

Returns: The dataset dimension of the diagram.

Definition at line 1138 of file KChartAbstractDiagram.cpp.

Hide (or unhide, resp.) a data cell.

Note: Hidden data are still taken into account by the coordinate plane, so neither the grid nor your axes' ranges will change, when you hide data. For totally removing data from KChart's view you can use another approach: e.g. you could define a proxy model on top of your data model, and register the proxy model calling setModel() instead of registering your real data model.

Parameters

index	The datapoint to set the hidden status for. With a dataset dimension of two, this is the index of the key of each key/value pair.
