isn't this the way how the plotting is done? in my experience (iirc), 
the following thing works (x, y1, y2 are numpy arrays):
pylab.ion()
a, = pylab.plot(x,y1)
b, = pylab.plot(x,y2)
...
y1 += 10
y2 += 20
a.set_ydata(y1)
b.set_ydata(y2)
pylab.draw()
y1 += 10
y2 += 20
a.set_ydata(y1)
pylab.draw()
in my experience BOTH plots get updated in this procedure, so i have to 
do first a deep copy in my case to get rid of these 'unwanted effects'...
best,

To make sure I capture all the events that can close the window, I
usually connect to the delete-event and the destroy-event. Eg::
 win.connect("delete_event", gtk.mainquit)
 win.connect("destroy_event", gtk.mainquit)
where win is your gtk window.
