Picking text outside of the axes region seems to be broken in matplotlib 0.99.1 and in the latest SVN. This functionality used to work in version 0.98.3. The example code pick_event_demo.py demonstrates the issue. The “ylabel” in the red box is no longer pickable. Is there a “clip_on” or similar setting on the picker that needs to be set now? Below is a simplified version of “pick_event_demo.py” for reference. I also added some text to the plot to make sure that text inside the axes region was still pickable.
Thanks,

Current “pick” implementation explicitly checks if the event is inside the axes.
So, you cannot pick artists outside the axes area. This seems more like an intended “feature” than a bug, but I may be wrong. And my guess is that this is to prevent picking invisible artists (as they are clipped).
While others may have better advice, mine is to use “button pressed” event directly.
lab = ax1.set_ylabel(‘ylabel’, picker=True, bbox=dict(facecolor=‘red’))
def picklabel(artsits, mouseevent):
for a in artsits:
a.pick(mouseevent)
from functools import partial
b1 = fig.canvas.mpl_connect(‘button_press_event’, partial(picklabel, [lab]))

Thanks for the workaround. I got it to work for the labels and title, but not axes tick labels.
This still seems like a regression bug to me. Especially since matplotlib’s own example code clearly shows that picking labels, titles, and tick labels outside the axes region should be possible with the standard picker. If the current picker behavior is the desired behavior, then the example code should at least be updated to show the new way to pick objects outside the axes.
Thanks again,
-Ben

I agree.
Unfortunately, event handling is not my specialty, and given no response from other developers, I recommend you file a bug (and hope other developers fix this).

I wrote the original functionality and example and do consider this a
regression, so do file a bug report and I'll try and get it fixed.

Here is the bug report and fix that caused the current regression
http://www.mail-archive.com/matplotlib-users@lists.sourceforge.net/msg11806.html
The solution I propose is to do the axes comparison test only when the
mouseevent.inaxes is not None (which happens when you are outside the
axes rectangle). Then you could pick artists associated with an axes
that are outside the rectangle, and still not get confused between two
different axes with the same coord system.
Try svn r8106.

Works for me! Although I did not test with Jorges's original code which caused the regression.
Do you still want me to file a bug report so the issue is tracked?
Thanks,
