## gsl-histogram: compute histogram of data on stdin

## 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 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.
