Grace is a free WYSIWYG 2D graph plotting tool, for Unix-like operating systems. The package name stands for "GRaphing, Advanced Computation and Exploration of data." Grace uses the X Window System and Motif for its GUI. It has been ported to VMS, OS/2, and Windows 9*/NT/2000/XP (on Cygwin). In 1996, Linux Journal described Xmgr (an early name for Grace) as one of the two most prominent graphing packages for Linux.[1]

Grace is a descendant of the ACE/gr (also known as Xmgr) plotting tool.[2] Xmgr was originally written by Paul Turner of Portland, Oregon,[3] who continued development until version 4.00.[4] In 1996, development was taken over by the ACE/gr development team, led by Evgeny Stambulchik at the Weizmann Institute of Science, Israel.[5][6] Development of Xmgr was frozen at version 4.1.2 in 1998[3] and the Grace project was started as a fork, released under the GPL.[7] The name stands for "GRaphing, Advanced Computation and Exploration of data" or "Grace Revamps ACE/gr"[6] Turner still maintains a non-public version of Xmgr for internal use.[6] The first version of Grace was numbered 5.0.0 and the latest stable version, 5.1.22 was released on 21 May 2008.[2] Development of the next major release 6.0.0 is in progress and preview versions numbered 5.99.* have been released.[8]
Grace creates publication-quality output. It can be used from a point-and-click interface or scripted (either from the built-in programming language or through a number of language bindings). It performs both linear and nonlinear least-squares fitting to arbitrarily-complex user-defined functions, with or without constraints. Other analysis tools include FFT, integration and differentiation, splines, interpolation and smoothing.
