Member Enumeration Documentation

◆ EAxisBoundsKind

enum ROOT::Experimental::RPadUserAxisBase::EAxisBoundsKind

Types of axis bounds to respect by the painter.

Non-fixed ones will be updated by the painter once the first paint has happened.

Enumerator
kAxisBoundsAuto	no defined axis range; the painter will decide
kAxisBoundsBegin	the axis begin is to be respected by the painter.
kAxisBoundsEnd	the axis end is to be respected by the painter.
kAxisBoundsBeginEnd	the axis minimum and maximum are to be respected by the painter
