Update plotting functions to use the new Matplotlib default styles
`ax.set_xlim(left, right)` in `_make_plot()` is used only if the Matplotlib version is <2.0.0

- closes #15495

is there a tests for this? can you rebase / update I think the original issue was in the meantime closed by https://github.com/pandas-dev/pandas/pull/16600 ? 
@TomAugspurger is this correct ? @jorisvandenbossche yep.

Thanks anyway @apcamargo. This is fixed on master now.
