I have implemented the preliminary changes required to
use the latest (0.9.16) version of JFreeChart. These
modifications require the latest JFreeChart binaries
(jfreechart and jcommon war files).
I have only tested the category, time series, and pie
charts with the new code to date and therefore make no
guarantees as to suitability for any particular chart type,
especially overlaid or combined charts and some of the
more complicated data series.
I have included a zip of the complete source tree. If
anyone makes further progress with the JFreeChart
update, please be considerate and post the changes
here. I have attempted to contact the project lead, but
my emails to him are getting bounced (??).
