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
