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 Li-
       brary.  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
