From the bandstructure.ipynb tutorial:

fermi_energy = results['scf_parameters'].dict.fermi_energy
results['band_structure'].show_mpl(y_origin=fermi_energy, plot_zero_axis=True)

Prints:

/home/aiidatests/venvs/aiida_py3.6/lib/python3.6/site-packages/matplotlib/font_manager.py:1241: UserWarning: findfont: Font family ['serif'] not found. Falling back to DejaVu Sans.
  (prop.get_family(), self.defaultFamily[fontext]))
