Lack of a good free plotting package is a sticking point for several
numerically-oriented interpreted languages. There has been some
discussion of this on the Numeric Python mailing list as well, and
perhaps a group effort spanning Octave, Python, Perl data language,
etc. could produce something. We'd like to see the most portable
possible solution, and the Tk driver in Plplot shows promise in that
direction, although the move of Geoff Furnish, the Plplot maintainer,
from Livermore to Los Alamos may have derailed that (there was also
some talk several months about about merging Plplot with gist, a
free Livermore graphics package that runs on X under Yorick or
Python). One person on the Python list is writing plotting software
in Java to run under Python (see http://estel.uindy.edu/PESSci/ph280/)
