Pal,
Normal autoscaling (when aspect is None, which is default) means to display
all the data that has been plotted. This is possible because the plotting
functions (which were given the data as input) updates the limits of the
"known data bounding box" for the axes. This data is not stored except
within each artist object, in their own form. It becomes difficult to then
"re-query" that data in the general case. It isn't to say that it isn't
possible to do, just that the architecture isn't set up to query subsets of
collections.
I hope this is clearer,
Ben Root
