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 plotting tool (also known as Xvgr), based on Xview libraries from OpenWindows.[2] Xvgr 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, 5.1.25 (released February 2015).[2] Whether the development of the next major release 6.0.0 is still in progress is unclear. The latest preview versions numbered 5.99.* were released in 2007.[8]

Currently maintained versions[edit]

Noteworthy alternate versions of Grace include GraceGTK, forked from Grace 5.1.22 in 2009 by Patrick Vincent,[9] and QtGrace, released in 2011 by Andreas Winter. [10] Both of these versions of Grace work natively on Windows operating systems and had releases in 2017.


Grace can be used from a point-and-click interface or scripted (using either the built-in programming language or 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.[11]
