In Unix, graph is a command-line utility used to draw plots from tabular data.

History

The graph utility, written by Douglas McIlroy, was present in the first version of Unix, and every later version, for instance:

Its output is a sequence of commands for the plot utility, which creates plots using ASCII graphics.

The GNU plotutils package provides a free non-exact reimplementation, available for Linux and many other systems. It can create plots in various graphics formats.

Usage

In its simplest use, the graph utility takes a textfile containing pairs of numbers, indicating the points of a line plot.

It outputs the line plot. Several options can be supplied to modify its behavior.
