The problems with PGPLOT licensing (and TJP's unwillingness to
support full RGB graphics) are why I would like to see PLPlot
developed more fully. To my mind, PGPLOT is a (formerly useful) dead
end - the installation issues have always been a concern, and are a
serious problem for PDL adoption now.
I'd like to see a similar high-level interface to the PGPLOT one, but
developed for Plplot, which is GPL.
I did formerly maintain the -cd<n> patch distributions to PGPLOT,
with the main advantages that they do chintzy RGB graphics and
perform anti-aliased resampling on pixel devices (at some cost in
speed), but Plplot is more universally compilable, GPLed, equally
(perhaps more device independent) and more thoughtfully implemented.
One there is a nice high-level interface to it within PDL, we can all
stop hassling about this stuff and get some work done! :-)
Cheers,
Craig

Sure. Sounds good.
I have to say, though, the navbar on pdl.perl.org looks a bit, um,
less than
fully impressive. That might push some away. Heck, upgrading the
website
every year or so makes people assured someone is paying attention
without
reading the list ;)
The graphics examples are certainly nice, but maybe it would be
nice if the
explanation of the commands used (inserted as single line # perl
comments?)
Another issue is ease of installation of PDL + a set of basic
support libs. I have it cracked now on Mac OS X but linux and
windows remain an issue. Linux is difficult because of the wide
variety of distros, however the all work with the IDL binary
distro so it may be doable.
From my perspective, you only need debian and redhat. I think many
other
distros can handle their formats.
But there is one problem with Debian, for sure. Graphics/PGPLOT/
PGPLOT.pm uses PGPLOT.pm but PGPLOT isn't in debian. I'm not a
debian developer, Perhaps I
should become one, for this.
FYI: I'm a professional perl programmer who took a good bit of math
in college.
I had this one problem for which a graphical 3d solution would be
ideal. Still haven't
figured out the right way to use points3d the way I want.
