Adds a diagram to this coordinate plane.

Parameters

diagram The diagram to add.

◆ gridAttributes()

const GridAttributes KChart::PolarCoordinatePlane::gridAttributes ( bool circular ) const

Returns: The attributes used for grid lines drawn in circular direction (or in sagittal direction, resp.).

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.

See also: setGridAttributes; resetGridAttributes; AbstractCoordinatePlane::globalGridAttributes; hasOwnGridAttributes

Definition at line 323 of file KChartPolarCoordinatePlane.cpp.

◆ hasOwnGridAttributes()

bool KChart::PolarCoordinatePlane::hasOwnGridAttributes ( bool circular ) const

Returns: Returns whether the grid attributes have been set for the respective direction via setGridAttributes( bool circular ).

If false, the grid will use the global attributes set by AbstractCoordinatePlane::globalGridAttributes (or the default attributes, resp.)

See also: setGridAttributes; resetGridAttributes; AbstractCoordinatePlane::globalGridAttributes

Definition at line 358 of file KChartPolarCoordinatePlane.cpp.

◆ layoutDiagrams()

◆ radiusUnit()

◆ resetGridAttributes()

void KChart::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.

See also: setGridAttributes, gridAttributes; AbstractCoordinatePlane::globalGridAttributes; hasOwnGridAttributes

Definition at line 316 of file KChartPolarCoordinatePlane.cpp.

◆ resizeEvent()

protected

Definition at line 128 of file KChartPolarCoordinatePlane.cpp.

◆ setGridAttributes()

void KChart::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.
