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 the histogram 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 no more  data  to  read  it  prints  out  the  accumulated  histogram  using
       gsl_histogram_fprintf.  If n is unspecified then bins of integer width are used.

EXAMPLE

       Here  is  an  example.  We generate 10000 random samples from a Cauchy distribution with a
       width of 30 and histogram them over the range -100 to 100, 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 the Cauchy  distribution
       with fluctuations caused by the finite sample size.

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