Thanks Matthias. That is a helpful example.
I have been trying to figure out how to recursively examine all the objects
in fig to see if there is a particular settable property. It seems like the
algorithm has to be recursive so that it goes deep into all the lists, etc.
I have not figured out how to know when you have reached the bottom/end of a
trail.
Such a function would let me set any text property in the whole figure
without needing to know if it was a text object, label, legend, etc... maybe
that is not as valuable as I think it would be though.

Hello John,
I'm not sure there is a better way, but the following works for me:
----------------------------------------------------------------------------
----------
from pylab import *
fig = figure()
# adding some subplots / axes instances
subplot(121)
x = linspace(-0.5, 1.5, 10)
plot(x, 0.5*x**2, 'ro', x, 0.33*x**3, 'bs') for i in [2, 4]:
subplot(2,2,i)
# get all axes of the figure 'fig' ...
allaxes = fig.get_axes()
# ... and reset their property x-limits setp(allaxes, 'xlim', (-.5, 1.5))
ax = allaxes[0]
# get all lines of the axes 'ax' ...
lines = ax.get_lines() # == ax.lines
# ... and reset their markerfacecolor
setp(lines, 'mfc', 'g')
show()
----------------------------------------------------------------------------
-----------
best regards
Matthias
