High quality graphics from LISP-STAT by
Jan De Leeuw
and Frederic Udina. It presents a mechanism to produce publishing
quality graphics by translating LISP-STAT internal representation of
graphics to a series of GnuPlot commands (Gnuplot is a public domain
graphics maker program running in most platforms).
A postscript version of the paper is available here and in UCLA-Stat server.
Lisp programs needed to do the job are also available here and in UCLA Stat server.
Windows and DOS versions of Gnuplot are stored in our server. A good Mac version (with translation to german, french, catalan and other european languages can be found here .
You may find these and other Gnuplot versions in most public domain software servers in the world.
Interactive data transformation and
parameter adjustment: a graphical interface tool .
A first version was presented in a
Workshop on Design and Implementation of Data Analysis Systems,
Heidelberg, March 23-26, 1995.
The current draft is available.
In the same directory there are some lisp-stat programs to work with it.
