GSL-HISTOGRAM(1)GSL-HISTOGRAM(1)NAMEgsl-histogram - compute histogram of data on stdin
SYNOPSYSgsl-histogram xmin xmax [n]
DESCRIPTIONgsl-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
