step option does not work for hist #23992
Description
Code Sample, a copy-pastable example if possible
import matplotlib.pyplot as plt import pandas as pd import numpy as np N = 1000 df = pd.DataFrame({ 'a': np.random.randint(0, 2, N), 'b': np.random.random(N) }) plt.figure() df.groupby('a').hist(histtype='step', ax=plt.gca()) plt.legend() plt.show()This is what I get:
Problem description
This function should create a step hist which is unfilled
- 'step' generates a lineplot that is by default unfilled.
Output of pd.show_versions()
