I agree with the sentiment that chaco is a very heavy and confusing 
package for the average scientist (but maybe great for the full-time 
programmer) but I'm really concerned about the idea that we need 
*another* solution started from scratch. There are already so many 
including scipy.gplt, scipy.plt, dislin, biggles, pychart, piddle, 
pgplot, pyx (new)...

In particular MatPlotLib looks promising - check out its examples:
*Many* plotting types already , simple syntax, a few different backends. 
And already has something of a following.

So is it really not possible for STScI to push its resources into aiding 
the development of something that's already begun? Would be great if we 
could develop a single package really well rather than everyone making 
their own.
