Your example works fine for me on R cocoa v1.01.    See below.

Click on the points of interest being displayed in the Quartz window.
Hit "ESC" if using Quartz device.
The labels show up on the graph at this point.
The error "no point with 0.25 inches" is returned if you clicked on the 
graph more than 0.25 inches from the closest point.
(I suppose it should read, "no point within 0.25 inches".)
