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.

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).

void AbstractDiagram::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.
