Detailed Description

Abstract base class for defining a variation across a 2D DP based on a histogram.

Abstract base class for defining a normalised variation across a 2D DP based on a histogram. The returned values are normalised to the total area. The histogram can be defined in the conventional DP (m13Sq vs m23Sq) or in the square DP and one half can be used to describe symmetric DPs.
