KDATA_PMFMEAN(3)

NAME
kdata_pmfmean - compute probability mass function mean of data

LIBRARY
libkplot

SYNOPSIS
#include <cairo.h>
#include <kplot.h>
double
kdata_pmfmean(const struct kdata *data);

DESCRIPTION
The kdata_pmfmean function compute the mean (i.e., expected value) of its data as if it were a probability mass function.

RETURN VALUES
If the data source has zero entries or the sum of the y values is 0.0, kdata_pmfmean returns 0.0. Otherwise, it returns the mean value.
