ROOT::Fit::DataRange Class Reference

class describing the range in the coordinates it supports multiple range in a coordinate.

The range dimension is the dimension of the coordinate, its size is the number of interval for each coordinate. Default range is -inf, inf Range can be modified with the add range method
