This bug or feature? is still in matplotlib 0.99.1.1 (Ubuntu 10.04 LTS)
More precisely scatter using symbols with zero area ('x', '+') will not
pick, regardless of the float value in picker.
Although this DOES work with plot, you can't vary the marker size between
points like you can with scatter.
I have also confirmed this in a version of the example in the docs
http://matplotlib.sourceforge.net/users/event_handling.html#picking-exercise
Which I could upload, but the code below is just fine.
If this is a feature, I suggest it be stated in the documentation.
