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 his- togram 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_his- togram_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 distri- bution 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 SEE ALSO gsl(3), gsl-randist(1).
