The 1.0.19 release in Maven does not include the FX classes. Code is in SVN and per the changelog it appears to be released for use, but it's not included in the distribution.
The JFreeChart library is significnatly more capable than the FX charts. I'm porting a Swing program over that uses JFreeChart and I woud like to continue reuse.
Thanks!
