Member Function Documentation

void KDChart::AbstractDiagram::aboutToBeDestroyed

(

)

[signal, inherited]

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

the attributes model, is invalidated.

Referenced by KDChart::AbstractDiagram::~AbstractDiagram().

void AbstractCartesianDiagram::addAxis

(

CartesianAxis *

axis )

[virtual, inherited]

Add the axis to the diagram.

The diagram takes ownership of the axis and will delete it.

To gain back ownership (e.g. for assigning the axis to another diagram) use the takeAxis method, before calling addAxis on the other diagram.

bool AbstractDiagram::allowOverlappingDataValueTexts

)

const [inherited]

Returns:

Referenced by KDChart::AbstractDiagram::compare().

AttributesModel * AbstractDiagram::attributesModel

(

)

const [virtual, inherited]

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

Returns:

a pointer to the AttributesModel currently used by this diagram.

int AbstractDiagram::datasetDimension

(

)

const [inherited]

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

For each dimension it will expect one column of values in the model. If the dimensionality is 1, automatic values will be used for the abscissa.

For example a diagram with the default dimension of 1, will have one column per datapoint (the y values) and will use automatic values for the x axis (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.

void KDChart::AbstractDiagram::layoutChanged

[signal, inherited]

Diagrams are supposed to emit this signal, when the layout of one of their element changes.

Layouts can change, for example, when axes are added or removed, or when the configuration was changed in a way that the axes or the diagram itself are displayed in a different geometry. Changes in the diagrams coordinate system also result in the layoutChanged() signal being emitted.

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:

model

The AttributesModel to use for this diagram.

See also:

AttributesModel, usesExternalAttributesModel

Sets an external AttributesModel on this diagram. By default, a diagram has it's own internal set of attributes, but an external one can be set. This can be used to share attributes between several diagrams. The diagram does not take ownership of the attributesmodel.
