I think you mean "create a subplot by using Figure.add_subplot"

Call set_xlim and set_ylim after calling plot. Plot automatically
calls autoscale on the axes to incorporate the new data into its
range. This should become an rc param and a kwarg (and this question
will soon become a FAQ!)

It has nothing to do with show and everything to do that setting the
lim come after creating the plot elements
