Commerical graphing packages?

While pyx is a very nice package, it is probably not a good choice for
web app developers simply because it generates postscript, which is
not very browser friendly.  Once could send the PS through a converter
such as ImageMagick, but it would probably be better to use a library
that generates browser friendly output natively.

matplotlib on the other hand, *does* work in web app servers, and
generates PNG/SVG natively.  See
http://matplotlib.sourceforge.net/faq.html#APPSERVER

Although it is a free and open source package, I think that the image
quality and support is on par with if not superior to what you find in
many commercial solutions.  If the OP wants commercial support, he
might consider contacting the developer off-list :-)
