Matplotlib直方图，条之间没有线条

Question

I want to plot a histogram with matplotlib that has lines delineating the histogram, but with no lines between the bars. Something like this:

How can I do that?

Answer 1

Using plt.hist() , you need to create the histogram using the argument histtype="stepfilled" and set the edgecolor of the patches, which is by default set to None, in order to get the histogram the way you desire:

import numpy as np
import matplotlib.pyplot as plt

data = np.random.randn(10000)

plt.hist(data, histtype="stepfilled", edgecolor='k', linewidth=1.2)
