Introduction
Grace is a WYSIWYG 2D plotting tool for the X Window System and
M*tif. Grace runs on practically any version of Unix-like OS. As well, it
has been successfully ported to VMS, OS/2, and Win9*/NT/XP (some minor
functionality may be missing, though).
Grace is a descendant of ACE/gr, also known as Xmgr.
