gsl-histogram

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 inte-
       ger 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
