◆ setLabelCollisionAvoidanceEnabled()

void PieDiagram::setLabelCollisionAvoidanceEnabled ( bool enabled )

If enabled is set to true, labels that would overlap will be shuffled to avoid overlap.

Note: Collision avoidance may allow labels to be closer than AbstractDiagram with allowOverlappingDataValueTexts() == false, so you should usually also call setAllowOverlappingDataValueTexts( true ) if you enable this feature.
