Okay, I've gotten this far. I have a Figure and I think I can change the formatting of the values displayed in the toolbar by setting taking the X axis and setting the function
format_xdata
to something of my own (something that computes lat/lon). Similar idea for the Y axis.
So, given my figure, how do I get the X and Y axis? All I see is gca(). But how can I get both? Using fig.get_axes() I only got 1 axis.
Anybody know?

I think this is a terminology issue: the axis objects returned by gca() or in the list returned by get_axes() incorporate both the ‘axes’ in the sense of x and y axes. With the single result of gca() you can get at both the x and y axes. For example:
import matplotlib.pyplot as plt
ax = plt.gca()
ax.set_xlims(xmin=-1)
ax.set_ylims(ymax=0)
ax.format_xdata = … # if this is how you use this bit - haven’t needed to change these myself
ax.format_ydata = …
I hope that helps,
Angus.

Thanks Angus. I tried this out ... it works once and only once!
BTW, The correct thing to do is
res=fig.gca()
res.fmt_xdata=foo() #instead of format_xdata
res.fmt_ydata=foo()
although, like I said, it only first for the first event. Somehow res.fmt_xdata is getting set back to None

Angus pointed out that I need to do
res.fmt_xdata=foo
Duh. I was evaluating foo.
But this still doesn't work!
The default formatting operation is still called.

This is the correct usage -- so if it is not working you need to post
a complete example. Perhaps you are not setting the correct Axes
instance?

The reason it wasn't working is that my function "foo" didn't have the right signature.fmt_xdata takes 1 argument. I have no idea why I didn't see an exception displayed.
It's working now that I have
def foo(x) pass
