Make sure the category of Mobile Device Royalties is selected and then UNCHECK the "Smooth" checkbox at the bottom of the graph. Now you should be able to move each individual point of the graph up and down as it recalculates the overall value forecast price.
My questions to you are:
1. Can I accomplish coding this chart with the use of Swing combined with JFreeChart?
2. Is there a better way to go about this that I don't know about?
Thanks for any help you can give!
EDIT: FIXED THE LINK SO NOW IT POINTS TO SOMETHING NOT 404
