HistogramAccumulator Class Reference

#include <genesis/utils/math/histogram/accumulator.hpp>

Detailed Description

Histogram helper class that collects data and builds a fitting Histogram.

This class can be used to collect data and automatically build a Histogram that fits to the data. It provides factory methods for differnt ways of initializing the Histogram ranges.

The max value used for the build Histogram will be determined using std::nextafter(max, max + 1) on the max element of the value list. The Histogram uses half-closed ranges like [a, b), so using the next-bigger value ensures that the max element of the Accumulator just fits into the range.

accumulate()

void accumulate	(	double	x,
		double	weight
	)

Definition at line 97 of file accumulator.cpp.

added_values()

size_t added_values

(

)

const

Return the number of values that have been added to the Accumulator.

This is simply the number of function calls to increment() and accumulate(). The count is reset when calling clear().
