◆ gridAttributes()

const GridAttributes KDChart::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.

◆ hasOwnGridAttributes()

bool KDChart::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.)

◆ resetGridAttributes()

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.

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

◆ setGridAttributes()

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.
