I wonder how to merge two charts and display on one frame. I have managed to create 'bell-curve'(Normal distribution) through JFreeChart with XYLine. However, I would like some part to be 'shaded', therefore would be good to use XYArea Chart. I have found an example (this website) how to use two XYLine Charts and display them. Please, see screenshot provided - blue line is prefered XYArea Chart display from that point.
I would appreciate any help. Please, bear in mind I am new to charts plotting in java, please explain 'clearly' how to achieve desired result.
P.S. is that posible to remove legends for red and blue lines ? (bottom legends on screenshot)
