Stephen,
Most likely, the program isn't really going back to the "original" axes as
much that it is automatically setting the axes to fit all the data from the
new plot (which would likely be the "original axes", but only by
coincidence). I am sure there is some sort of easy way to do this, but the
brute-force way would be for any action to create a plot to first check and
see what the current x and y lims are and save them to temporary variables.
Then, after creating the plots, call set the x and y lims from the temporary
variables.
Note that there might be an issue with the first graph, because you don't
want to set the axes after creating the graph using the information prior to
the graphing. I don't know how one would detect that, besides some sort of
counter and an if-statement.
Maybe someone else has a better way?
