This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.

Or were you looking for a way to have JFC calculate the trend automatically from a given Dataset? It doesn't have provisions for that.
Yes, I was hoping for JFC to do the work. But if it can't your first suggestion is the direction I will go.
Do you have any or can you direct me to any examples?
