ROOT::Experimental::Detail::RHistBinRef< HISTIMPL > Class Template Reference

template<class HISTIMPL>
class ROOT::Experimental::Detail::RHistBinRef< HISTIMPL >

Represents a bin reference.

Value of the bin iteration.

Provides access to bin content, bin geometry (from, to, center), and statistics (for instance higher moments) associated to the bin.
