RooUniformBinning Class Reference

RooUniformBinning is an implementation of RooAbsBinning that provides a uniform binning in 'n' bins between the range end points.

A RooUniformBinning is 'elastic': if the range changes the binning will change accordingly, unlike e.g. the binning of class RooBinning.
