Several graphical user interfaces have been written for `gnuplot` and one for win32 is included in this distribution.
Bruce Ravel (ravel@phys.washington.edu) has written a gnuplot-mode for GNU emacs and XEmacs based on the earlier gnuplot.el file by Gershon Elber. While the gnuplot CVS repository has its own copy the most recent version of this package is available from http://feff.phys.washington.edu/~ravel/software/gnuplot-mode/ For Python, Tk/Tcl, and other front-ends, check the links on http://gnuplot.sourceforge.net/links.html
