Detailed Description

template<typename ValueType = UInt, typename BinSizeType = double>
class OpenMS::Math::Histogram< ValueType, BinSizeType >

Representation of a histogram.

The first template argument gives the Type of the values that are stored in the bins. The second argument gives the type for the bin size and range.
