Seaborn boxplot

This example shows how to use seaborn to draw a box plot showing the distributions of eigenvalues with respect to the band index.

from abipy.abilab import abiopen
import abipy.data as abidata

# Open the file with energies computed with a homogeneous sampling
# of the BZ and extract the band structure.
with abiopen(abidata.ref_file("si_scf_GSR.nc")) as gsr:
    ebands = gsr.ebands

import matplotlib.pyplot as plt
# Use `swarm=True` to show the datapoints on top of the boxes
ebands.boxplot(swarm=True)
plt.show()
