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.

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.

bool AbstractDiagram::percentMode ( ) const [inherited]

Returns whether this diagram is drawn in percent mode.

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).

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

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:
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.

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 KD Chart'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:

hiddenThe hidden status to set.
