If I were trying to do this, I'd cobble something together using by the
minor and major formatters.
e.g.,...
import matplotlib.dates as mdates
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
majorLocs = mdates.MonthLocator(bymonth[1,7])
majorFmt = mdates.DateFormatter('%b\n%Y')
minorLocs = mdates.MonthLocator(bymonth[1,7])
minorFmt = mdates.DateFormatter('%b')
ax.xaxis.set_major_locator(majorLocs)
ax.xaxis.set_major_formatter(majorFmt)
ax.xaxis.set_minor_locator(minorLocs)
ax.xaxis.set_minor_formatter(minorFmt)
