Hello all

My specific question is this:

Suppose I have a figure, with an axes object, and an XY plot:

## ···

#-------

import matplotlib

import pylab as P

t = P.arange(0.0,1.0,0.02)

x = P.sin(2*P.pi*t)

y = P.exp(-t*3.)*P.cos(3*P.pi*t)

ff = P.Figure(figsize=(5,4), dpi=100)

ss = P.subplot(222)

pp = ss.plot(x,y,'.-')

# some program resets x,y limits

P.show()

#-----

(Sorry for my matlab-tainted language):

I would like to use ff.gca() to get the handle of the

active axes object (which should be ss) and then

determine the indices into the original data (x,y)

which reflect the points showing in the current

axis limits (whatever they have been set to)

Is there any way to

- find the axes objects that count "ff" as their parent?

- access the x,y points as "children" of the axes object ss?

I may be approaching my larger goal the wrong way,

but I am still interested in this question.

Thanks,

Jules
