Pivot
Pivoting allows the user to auto-switch around the positions of hierarchy or value chips in two drop zones. In effect, it's an attempt to pivot the visual logically, potentially showing the data in a more interesting way or highlighting relationships in the data and seeing them in a different light. More simplistically, Pivoting allows the user to make better use of screen real-estate, potentially laying out the visual in a more efficient manner by moving certain elements around.

Pivot Behaviors
The Pivot function changes its behavior depending on the visual being used.
Note: There is no logical way of pivoting data in a mapping visual - so the feature is disabled.
