NAME

gsl-histogram - compute histogram of data on stdin

SYNOPSYS

gsl-histogram xmin xmax [n]

DESCRIPTION

gsl-histogram is a demonstration program for the GNU Scientific Library.It takes three arguments, specifying the upper and lower bounds of thehistogram and the number of bins. It then reads numbers from `stdin',one line at a time, and adds them to the histogram. When there is nomore data to read it prints out the accumulated histogram usinggsl_histogram_fprintf. If n is unspecified then bins of integer widthare used.

EXAMPLE

Here is an example. We generate 10000 random samples from a Cauchydistribution with a width of 30 and histogram them over the range -100 to100, using 200 bins.

gsl-randist 0 10000 cauchy 30 | gsl-histogram -100 100 200 > histogram.dat
A plot of the resulting histogram will show the familiar shape of theCauchy distribution with fluctuations caused by the finite samplesize.

awk '{print $1, $3 ; print $2, $3}' histogram.dat | graph -T X
