Grace Plotting Software http://plasma-gate.weizmann.ac.il/Grace/ Grace plotting software with convenient graphical interface and publication quality output is available at this site for free download (under public license). The software was developed by the Plasma Laboratory of Weizmann Institute of Science. The site describes Grace as, "... a WYSIWYG tool to make two-dimensional plots of scientific data. It runs under various (if not all) flavors of Unix with X11 and M*tif (LessTif or Motif). It also runs under VMS, OS/2, and Windows (95/98/NT). Its capabilities are roughly similar to GUI-based programs like Sigmaplot or Microcal Origin plus script-based tools like Gnuplot or Genplot. Its strength lies in the fact that it combines the convenience of a graphical user interface with the power of a scripting language which enables it to do sophisticated calculations or perform automated tasks." Grace is derived from Xmgr (a.k.a. ACE/gr). The latest version, 5.1.2, was just released October 9, 2000. Grace's capabilities include linear and non-linear least squares with residuals, splines, histograms, smoothing, correlation, and more. It also contains a built-in programming language. FAQs, a tutorial, mailing list, and bug reports are also found at the Grace site.
