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.

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.

QModelIndex AbstractDiagram::attributesModelRootIndex ( ) const [protected, inherited]

QBrush AbstractDiagram::brush ( const QModelIndex & index ) const [inherited]

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.

QBrush AbstractDiagram::brush ( int dataset ) const [inherited]

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:

const QPair< QPointF, QPointF > AbstractDiagram::dataBoundaries ( ) const [inherited]

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

This method returns a chached 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.

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 ( AbstractDiagram * ) [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.

void AbstractCartesianDiagram::setAttributesModel ( AttributesModel * amodel ) [virtual, inherited]

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:

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.

Hide (or unhide, resp.

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.

Parameters:

hidden
