What's a good java graphing chart tool?

I was trying to find a good graphing chart tool that would be good to use in java. I know of the chart fx tool but this is written in components and the clients are looking for a java based charting program. I also came across a visual mining application that had a lot of graphing capabilities:

Can any of you give me suggestions on some tools and adv. vs disadv.

thanks,
