Subject: selecting data within a contour level

Hi all

I have a 2d contour graph, what i want to do is click a contour level
on the plot with the mouse and return the x y data within the contour
level. Say if i click the second contour level the first and second
contour levels are returned etc etc has anyone got any idea how to do
this ?

thanks in advance for any help
