Hi all, I was wondering if anyone could help me with a problem I'm struggling with. I have written a program that uses a GUI to take in user data, number crunches the data, then plots several individual plots on the same figure with the data. I would like to be able to then click on a point on one of the plots and have the actual data from that point displayed and returned within the program, so I can use it to look up some property in a data matrix associated with the data point, and output it to the user. I've tried to use buttondownfcn, but it won't work if I click on a curve. Any help on this issue would be greatly appreciated.
