int AbstractArea::bottomOverlap ( bool doNotRecalculate = false ) const [virtual, inherited]

This is called at layout time by KDChart:AutoSpacerLayoutItem::sizeHint().

The method triggers AbstractArea::sizeHint() to find out the amount of overlap at the bottom edge of the area.

Note:: The default implementation is not using any caching, it might make sense to implement a more sophisticated solution for derived classes that have complex work to do in sizeHint(). All we have here is a primitive flag to be set by the caller if it is sure that no sizeHint() needs to be called.

Note:: This function always returns a valid set of grid attributes: If no special grid attributes were set for this direction the global attributes are returned, as returned by AbstractCoordinatePlane::globalGridAttributes.

KDChart::DataDimensionsList KDChart::AbstractCoordinatePlane::gridDimensionsList ( ) [inherited]

Returns the dimensions used for drawing the grid lines.

Returned data is the result of (cached) grid calculations, so - if you need that information for your own tasks - make sure to call again this function after every data modification that has changed the data range, since grid calculation is based upon the data range, thus the grid start/end might have changed if the data was changed.

Note:: Returned list will contain different numbers of DataDimension, depending on the kind of coordinate plane used. For CartesianCoordinatePlane two DataDimension are returned: the first representing grid lines in X direction (matching the Abscissa axes) and the second indicating vertical grid lines (or Ordinate axes, resp.).

Returns:: The dimensions used for drawing the grid lines.

AbstractCoordinatePlane * KDChart::AbstractCoordinatePlane::referenceCoordinatePlane ( ) const [inherited]

There are two ways, in which planes can be caused to interact, in where they are put layouting wise: The first is the reference plane.

If such a reference plane is set, on a plane, it will use the same cell in the layout as that one. In addition to this, planes can share an axis. In that case they will be laid out in relation to each other as suggested by the position of the axis. If, for example Plane1 and Plane2 share an axis at position Left, that will result in the layout: Axis Plane1 Plane 2, vertically. If Plane1 also happens to be Plane2's reference plane, both planes are drawn over each other. The reference plane concept allows two planes to share the same space even if neither has any axis, and in case there are shared axis, it is used to decided, whether the planes should be painted on top of each other or laid out vertically or horizontally next to each other.

Returns:: The reference coordinate plane associated with this one.

	diagram	The diagram to be used instead of the old diagram. This parameter must not be zero, or the method will do nothing.
	oldDiagram	The diagram to be removed by the new diagram. This diagram will be deleted automatically. If the parameter is omitted, the very first diagram will be replaced. In case, there was no diagram yet, the new diagram will just be added.

Note:: If you want to re-use the old diagram, call takeDiagram and addDiagram, instead of using replaceDiagram.

void KDChart::PolarCoordinatePlane::resetGridAttributes ( bool circular )

Reset the attributes to be used for grid lines drawn in circular direction (or in sagittal direction, resp.

). By calling this method you specify that the global attributes set by AbstractCoordinatePlane::setGlobalGridAttributes be used.

int AbstractArea::rightOverlap ( bool doNotRecalculate = false ) const [virtual, inherited]

This is called at layout time by KDChart::AutoSpacerLayoutItem::sizeHint().

The method triggers AbstractArea::sizeHint() to find out the amount of overlap at the right edge of the area.

Note:: The default implementation is not using any caching, it might make sense to implement a more sophisticated solution for derived classes that have complex work to do in sizeHint(). All we have here is a primitive flag to be set by the caller if it is sure that no sizeHint() needs to be called.

void KDChart::AbstractCoordinatePlane::setGlobalGridAttributes ( const GridAttributes & a ) [inherited]

Set the grid attributes to be used by this coordinate plane.

To disable grid painting, for example, your code should like this:

 GridAttributes ga = plane->globalGridAttributes();
 ga.setGlobalGridVisible( false );
 plane->setGlobalGridAttributes( ga );

void KDChart::PolarCoordinatePlane::setGridAttributes	(	bool	circular,
		const GridAttributes &	a
	)

Set the attributes to be used for grid lines drawn in circular direction (or in sagittal direction, resp.

).

To disable circular grid painting, for example, your code should like this:

 GridAttributes ga = plane->gridAttributes( bool );
 ga.setGridVisible( false );
 plane-setGridAttributes( bool, ga );

Note:: setGridAttributes overwrites the global attributes that were set by AbstractCoordinatePlane::setGlobalGridAttributes. To re-activate these global attributes you can call resetGridAttributes.

Inform the item about its widget: This enables the item, to trigger that widget's update, whenever the size of the item's contents has changed.

Thus, you need to call setParentWidget on every item, that has a non-fixed size.
