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.

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.

Replaces the old diagram, or appends the diagram, it there is none yet.

diagramThe diagram to be used instead of the old diagram. This parameter must not be zero, or the method will do nothing.
oldDiagramThe 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.

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:

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

void AbstractCoordinatePlane::takeDiagram ( AbstractDiagram diagram)
virtualinherited

Removes the diagram from the plane, without deleting it.

The plane no longer owns the diagram, so it is the caller's responsibility to delete the diagram.

int AbstractArea::topOverlap ( bool  doNotRecalculate = false) const
virtualinherited

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

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