Former Gnu users may be pleased with many of the new features
(many inspired by your suggestions!), but will also find many changes.
GNUPLOT will not run all Gnu
input files unchanged.
Several Gnu
features were not included in GNUPLOT because they
were specific to the
driver. I encourage you to use the newer
GNUPLOT. A translator is available that attempts to translate your
old Gnu
1.6 input files into GNUPLOT 3.0 files. You can ftp it
from cs.duke.edu as dist/sources/gnuplot/gnut2p.tar.Z.
This file also contains directions and a list of changes from Gnu
to GNUPLOT.
