	Lower axis edge.

	Upper axis edge.

	========================================================================== Bins ========================================================================== -------------------------------------------------------------------------- Number of bins Number of in-range bins in the axis.

	-------------------------------------------------------------------------- Bin edges Lower edge of the in-range bin identified by index.
virtual double	binUpperEdge ( int index ) const = 0
	Upper edge of the in-range bin identified by index.

	========================================================================== Conversions between coordinates and bin indices ========================================================================== Equivalent to coordToIndex( coord ); for 1D histogram or coordToIndexX( coordX ); or coordToIndexY( coordY ); for 2D histogram.

Detailed Description

Definition of the IAxis interface class IAxis represents a binned histogram axis.
