Re: Declarative Charts Generation Proposal

this sounds kinda like what Krysalis Wings was trying to do.

I was also starting a little Swing app that lets you interactively layout a chart and save the
properties in XML, which could then be read in and used by the jcharts api.  Did not get too far
with this as I have had no time as of late; I am trying to start a buisness on the side and
between that and my day job, i have no time for anything else.
