The call to autoscale_view overrides the earlier calls to set_xlim and
set_ylim. There is no built-in mechanism for autoscaling only the upper
limit, and holding the lower limit fixed. You could make such a
mechanism by writing a custom Locator, but it may make more sense to
calculate the upper limit directly in your code based on your data, and
then use set_xlim and set_ylim to set both ends of each axis.
