Detailed Description

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

Constructor & Destructor Documentation

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

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

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

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.
bool add ( const Histogram other)
inline

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

uint64_t count ( int  n) const
inline

Return the number of samples in the nth bin.

double max ( ) const
inline

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

double max ( int  n) const
inline

Return the maximum value in the nth bin.

double min ( ) const
inline

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

double min ( int  n) const
inline

Return the minimum value in the nth bin.

size_t numBins ( ) const
inline

Return the number of bins in this histogram.

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

Print the histogram to the specified output stream.

uint64_t size ( ) const
inline

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