I'm guessing your problem was that only the year was being shown,
regardless? It would seem the problem stems from the fact that while
you give your formatter the AutoDateLocator, you never tell the axis
to use this. I got what I considered the correct behavior by adding
the following line at linen 84 in the script:
self.subplot.xaxis.set_major_locator(adl)
Does adding that get you what you want?
