If you actually ran that code and still suggest it as the fix, then I
think you must be joking.  Pushing the axes into the middle of the
data cloud in order to make them cross is certainly not making a very
nice looking plot. Not only are there observations outside the area
framed by the axes, but there are axis labels that are overlapped by
observations and by the axes themselves.
