[Matplotlib-users] How to control the y feedback value?

[Skip M. <sk...@po...>]

I have a plot which uses both the left and right y axes.  See
attached. Note that the feedback in the lower right-hand corner
displays the value on the right y axis (the blue plot). That's not a
very interesting value though. How can I control which value is
displayed as I move the cursor around the graph? Is it something
control interactively with a modifier key?  I tried a few, but saw no
change. I'm currently using matplotlib v 1.1.0 (alas, something which
is also out of my control).

Thanks,

Skip
