## Member Function Documentation

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.

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.

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 AbstractDiagram::setAttributesModel | ( | AttributesModel * | model | ) | `[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 explicitely 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.

void AbstractDiagram::setHidden | ( | bool | hidden | ) | `[inherited]`

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:

  hidden | The hidden status to set.
