# Description of the program: histogram

This program estimates the scalar distribution of a data set. It computes the distribution at a given number of points in the interval spanned by the data by integrating over a given neighborhood.

## Usage:

histogram [Options]

Everything not being a valid option will be interpreted as a potential datafile name. Given no datafile at all, means read stdin. Also - means stdin

Possible options are:

Option | Description | Default
--- | --- | ---
-l# | number of data to use | whole file
-x# | number of lines to be ignored | 0
-c# | column to read or datafile,# | 1
-b# | number of base points | 50
-e# | size of the boxes (data are internally rescaled to [0:1]) | 2/base
-o[#] | output datafile | without file name: 'datafile'.his (or stdin.his if data were read from stdin) If no -o is given stdout is used
-h | show these options | none

## Description of the output:

The first three lines contain 1. interval of the data, 2. the average of the data and 3. the standard deviation of the data. The following lines then contain the histogram.
If you are only interested in the first three lines set the value of the -b flag to 0.
