[Matplotlib-users] Picking on a scatter plot. Copy of positions needed?

[V. A. S. <so...@es...>]

Hello,

Looking at the picking demo:

http://matplotlib.org/examples/event_handling/pick_event_demo.html

I see that one can recover the coordinates from the picked artist in the 
case of images, and lines. However, in case 3 of the example (scatter 
plot) the x and y data have to be supplied in order to retrieve the 
coordinates. Is there a way to recover them from the artist? I got the 
(wrong?) feeling that the data must be hidden somewhere ... If that is 
not possible I'll have to keep a copy of the data used to generate the 
artist, but I would not like to do so.

Any hint?

Thanks,

Armando
