## Detailed Description

This class computes a histogram, with a fixed interval width, of a population of floating-point values.

## Constructor & Destructor Documentation

## ◆ Histogram() [1/2]

Histogram | ( | double | min,
|  | double | max,
|  | size_t | numBins = `10`
| ) |  |
| inline

Construct with given minimum and maximum values and the given bin count.

## ◆ Histogram() [2/2]

Histogram | ( | const Stats & | s,
|  | size_t | numBins = `10`
| ) |  |
| inline

Construct with the given bin count and with minimum and maximum values taken from a Stats object.

## Member Function Documentation

## ◆ add() [1/2]

bool add | ( | const Histogram & | other | ) |
| inline

Add all the contributions from the other histogram, provided that it has the same configuration as this histogram.

## ◆ add() [2/2]

bool add | ( | double | val,
|  | uint64_t | n = `1`
| ) |  |
| inline

Add n samples with constant value val, provided that the val falls within this histogram's value range.

Returns
  `true` if the sample value falls within this histogram's value range.

## ◆ count()

uint64_t count | ( | int | n | ) | const
| inline

Return the number of samples in the nth bin.

## ◆ max() [1/2]

double max | ( |  | ) | const
| inline

Return the upper bound of this histogram's value range.

## ◆ max() [2/2]

double max | ( | int | n | ) | const
| inline

Return the maximum value in the nth bin.

## ◆ min() [1/2]

double min | ( |  | ) | const
| inline

Return the lower bound of this histogram's value range.

## ◆ min() [2/2]

double min | ( | int | n | ) | const
| inline

Return the minimum value in the nth bin.

## ◆ numBins()

size_t numBins | ( |  | ) | const
| inline

Return the number of bins in this histogram.

## ◆ print()

void print | ( | const std::string & | name = `""`,
|  | std::ostream & | strm = `std::cout`
| ) |  | const
| inline

Print the histogram to the specified output stream.

## ◆ size()

uint64_t size | ( |  | ) | const
| inline

Return the population size, i.e., the total number of samples.
