◆ 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.

Definition at line 128 of file KDChartPolarCoordinatePlane.cpp.

◆ 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 );
void setGridAttributes(bool circular, const GridAttributes &)
Note
setGridAttributes overwrites the global attributes that were set by AbstractCoordinatePlane::setGlobalGridAttributes. To re-activate these global attributes you can call resetGridAttributes.

◆ setStartPosition()

void PolarCoordinatePlane::setStartPosition ( qreal  degrees)

Specify the rotation of the coordinate plane.

In a pie diagram this indicates the position where the first pie starts, in a polar diagram it specifies the Zero position of the circular axis:
