Member Function Documentation

void KDChart::AbstractDiagram::aboutToBeDestroyed ( )
signalinherited

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)
virtualinherited

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.

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.

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

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.

inherited

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

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 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.

void KDChart::AbstractDiagram::layoutChanged ( AbstractDiagram )
signalinherited

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.

If true, all data points in the same column of a diagram will be be drawn at the same X coordinate and stacked up so that the distance from the last data point (or the zero line) to a data point P is always the ratio of (Y-Value of P)/ (sum of all Y-Values in same column as P) relative to the diagrams height (or width, if abscissa and ordinate are swapped).

void AbstractCartesianDiagram::setAttributesModel ( AttributesModel amodel)
virtualinherited

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.
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.

Parameters
amodelThe AttributesModel to use for this diagram.
