In some plots, rot and fontsize arguments are not applied properly.

• timeseries line / area plot: rot is not applied to minor ticklabels, and fontsize is completely ignored. (Fixed to apply to xticklabels)
• kde plot: rot and fontsize are completely ignored. (Fixed to apply to xticklabels)
• scatter and hexbin plots: rot and fontsize are completely ignored. (Under confirmation)

import pandas as pd
import numpy as np

df = pd.DataFrame(np.random.randn(10, 4), index=pd.date_range(start='2014-07-01', freq='M', periods=10))
df.plot(rot=80, fontsize=15)
