UserWarning for pandas dataframe plot with errors #4917
Description
Only when I add the yerr option to this pandas dataframe plot I'm getting this matplotlib UserWarning:
df.FUV_CHIP_TEMP_C.plot(yerr=std)
WARNING:py.warnings:/Users/klay6683/miniconda3/lib/python3.4/site-packages/matplotlib-1.5.dev1-py3.4-macosx-10.5-x86_64.egg/matplotlib/collections.py:356: UserWarning: Collection picker None could not be converted to float
% self._picker)at the exact moment the mouse pointer hovers over the plotting area.
std is a dataframe with the exact same shape and columns as df and the plotting seem to makes sense. Thought I let you know of this irritating warning though.
This does not happen when I do not use the yerr option.
MPL: ''1.5.dev1'' (GH master from today: 3f758ab)
Platform: OSX 10.10.4
Backend: qt
Edit: Let me know if this should go to pandas, then I move it over there.

It is coming out of a Collection object (which is how error bars are implemented). The reason you are seeing this on master on mouse over is the hitlist computation a part of the hover feature (plot imshow to see the reason for this)
This should be ameliorated by #4813 which restricts the things that it tries to hit greatly.

I'll close for lack of a reproducible example. Feel free to ask for a re-open....
