Description

GSL-HISTOGRAM(1)            General Commands Manual           GSL-HISTOGRAM(1)



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 > his-
       togram.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
