Abstractgnuplot, under active development since 1986, is an interactive plotting utility for UNIX, IBM OS/2, MS Windows, DOS, Apple Macintosh, VMS, Atari and many other platforms. It is free and open source, though it is not licensed under the GPL, nor is it GNU software. gnuplot supports a number of ‘terminal’ types including interactive screen terminals, pen plotters, printers, and pseudo‐devices like LATEX, metafont, pdf, svg, and bitmap png. As of version 4.0 it also incorporates nonlinear regression routines (formerly gnufit). This software may be of interest to econometricians, particularly those who use LATEX in their work.
