Detailed Description

template<std::size_t Dim>
class Acts::Experimental::Histogram< Dim >

Multi-dimensional histogram wrapper using boost::histogram for data collection.

This class wraps boost::histogram to provide a ROOT-independent histogram implementation with compile-time dimensionality.

Template Parameters

Dim	Number of dimensions

Constructor & Destructor Documentation

Histogram()

template<std::size_t Dim>

Acts::Experimental::Histogram< Dim >::Histogram	(	std::string	name,
		std::string	title,
		const std::array< AxisVariant, Dim > &	axes )

Construct multi-dimensional histogram from axes.

Parameters

name	Histogram name (for identification and output)
title	Histogram title (for plotting)
axes	Array of axes with binning and metadata
