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.

Definition at line 47 of file KChartAbstractDiagram.h.

Member Function Documentation

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.

bool AbstractDiagram::allowOverlappingDataValueTexts ( ) const
Returns
Whether data value labels are allowed to overlap.

Definition at line 365 of file KChartAbstractDiagram.cpp.

bool AbstractDiagram::antiAliasing ( ) const
Returns
Whether anti-aliasing is to be used for rendering this diagram.

Definition at line 376 of file KChartAbstractDiagram.cpp.

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 199 of file KChartAbstractDiagram.cpp.

void KChart::AbstractDiagram::attributesModelAboutToChange ( AttributesModel newModel,
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.

QModelIndex AbstractDiagram::attributesModelRootIndex ( ) const
protected

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

Definition at line 224 of file KChartAbstractDiagram.cpp.

void KChart::AbstractDiagram::boundariesChanged ( )
signal

Emitted upon change of a data boundary.

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 890 of file KChartAbstractDiagram.cpp.

QBrush AbstractDiagram::brush ( int  dataset) const

Retrieve the brush to be used for the given dataset.

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

Parameters
datasetThe dataset to retrieve the brush for.
Returns
The brush to use for painting.

Definition at line 895 of file KChartAbstractDiagram.cpp.

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
indexThe 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 903 of file KChartAbstractDiagram.cpp.

bool AbstractDiagram::compare ( const AbstractDiagram other) const

Returns true if both diagrams have the same settings.

Definition at line 66 of file KChartAbstractDiagram.cpp.

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 108 of file KChartAbstractDiagram.cpp.

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 113 of file KChartAbstractDiagram.cpp.

void AbstractDiagram::dataChanged ( const QModelIndex topLeft,
const QModelIndex bottomRight,
const QVector< int > &  roles = QVector<int>() 
)

Definition at line 245 of file KChartAbstractDiagram.cpp.

void KChart::AbstractDiagram::dataHidden ( )
signal

This signal is emitted, when the hidden status of at least one data cell was (un)set.

QList< QBrush > AbstractDiagram::datasetBrushes ( ) const

The set of dataset brushes currently used, for use in legends, etc.

Note
Cell-level override brushes, if set, take precedence over the dataset values, so you might need to check these too, in order to find the brush, that is used for a single cell.
Returns
The current set of dataset brushes.

Definition at line 1093 of file KChartAbstractDiagram.cpp.

int AbstractDiagram::datasetDimension ( ) const

The dataset dimension of a diagram determines how many value dimensions it expects each datapoint to have.

For each dimension and data series it will expect one column of values in the model. If the dimension is 1, automatic values will be used for X.

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 1144 of file KChartAbstractDiagram.cpp.

QStringList AbstractDiagram::datasetLabels ( ) const

The set of dataset labels currently displayed, for use in legends, etc.

Returns
The set of dataset labels currently displayed.

Note
Cell-level override markers, if set, take precedence over the dataset values, so you might need to check these too, in order to find the marker, that is shown for a single cell.
Returns
The current set of dataset brushes.

Definition at line 1119 of file KChartAbstractDiagram.cpp.

QList< QPen > AbstractDiagram::datasetPens ( ) const

Note
Cell-level override pens, if set, take precedence over the dataset values, so you might need to check these too, in order to find the pens, that is used for a single cell.
Returns
The current set of dataset pens.

Definition at line 1106 of file KChartAbstractDiagram.cpp.

Note that this property is not applicable to all diagram types.

Definition at line 387 of file KChartAbstractDiagram.cpp.

void KChart::AbstractDiagram::propertiesChanged ( )
signal

Emitted upon change of a property of the Diagram.

void AbstractDiagram::resize ( const QSizeF area)
virtual

Parameters
allowTrue means that overlapping labels are allowed.

Definition at line 356 of file KChartAbstractDiagram.cpp.

void AbstractDiagram::setAntiAliasing ( bool  enabled)

Set whether anti-aliasing is to be used while rendering this diagram.

Parameters
enabledTrue means that AA is enabled.

Definition at line 370 of file KChartAbstractDiagram.cpp.

void AbstractDiagram::setAttributesModel ( AttributesModel model)
virtual

Associate an AttributesModel with this diagram.

Note that the diagram does not take ownership of the AttributesModel. This should thus only be used with AttributesModels that have been explicitly created by the user, and are owned by her. Setting an AttributesModel that is internal to another diagram is an error.

Correct:

AttributesModel *am = new AttributesModel( model, 0 );
diagram1->setAttributesModel( am );
diagram2->setAttributesModel( am );

Wrong:

diagram1->setAttributesModel( diagram2->attributesModel() );
Parameters
modelThe AttributesModel to use for this diagram.

bool  hidden 
)

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
indexThe 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.
hiddenThe hidden status to set.

Definition at line 257 of file KChartAbstractDiagram.cpp.

Hide (or unhide, resp.) a dataset.

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.
