History
Several utilities were inspired by
Bell Laboratories
. By the time of Version 7 Unix, graph, plot, spline, and several device-dependent versions of libplot were standard Unix features. The first display device supported by the package was a Tektronix 611 storage scope. By the early 1980s, numerous other devices were supported.
In 1989, the first GNU versions of graph, plot, tek2plot, spline and their respective documentation were written. Richard Stallman further directed development of the programs and documentation. The distribution, as it stood in 1991, was distributed under the name GNU graphics.
In 1995, the package was significantly expanded by writing a device-independent, standalone version of libplot, and by rewriting graph from scratch, turning it into a real-time filter.
