NAME

histify - generate simple histograms from streamed data

SYNOPSIS

  generator | histify [--nbins=X] [--min=X] [--max=X] \
                      [--desc=<center|left|right|number|none>]

Reads whitespace-separated numbers from STDIN and generates a histogram. If no histogram boundaries are specified using options, the number of bins defaults to 10 and the min/max are extracted from the data. That means reading all data into memory. If you specify min/max, the program works with constant memory overhead.

Prints the resulting histogram contents one bin per line.

Using --desc=<type> adds an extra column to the output before the histogram content (separated by a tab) that can be any one of: The bin "number", the bin "center", the "left" bin boundary, or the "right" bin boundary.
