Member Function Documentation

normalize()

template<typename GroupAxisT, typename... AxisT>

void Rivet::HistoGroup< GroupAxisT, AxisT >::normalize ( const double normto = 1.0, const bool includeOverflows = true )

inline

Normalize the (visible) histo "volume" to the normto value.

Note

Consider each sub-histogram separately when calculating the integral.

normalizeGroup()

template<typename GroupAxisT, typename... AxisT>

void Rivet::HistoGroup< GroupAxisT, AxisT >::normalizeGroup ( const double normto = 1.0, const bool includeOverflows = true )

inline

Normalize the (visible) histo "volume" to the normto value.

Note

Treat the histogram group as an entity when calculating the integral.

References integral(), MSG_DEBUG, and scaleW().

reset()

template<typename GroupAxisT, typename... AxisT>

void Rivet::HistoGroup< GroupAxisT, AxisT >::reset ( )

inlinenoexcept

Reset the histogram.

Keep the binning but set all bin contents and related quantities to zero
