Python histogram outline
提问by Brad Reed
I have plotted a histogram in Jupyter (Python 2) and was expecting to see the outlines of my bars but this is not the case.
我已经在 Jupyter (Python 2) 中绘制了一个直方图，并希望看到我的条形轮廓，但事实并非如此。
I'm using the following code:
我正在使用以下代码：
import matplotlib.pyplot as plt
from numpy.random import normal
gaussian_numbers = normal(size=1000)
plt.hist(gaussian_numbers)
plt.title("Gaussian Histogram")
plt.xlabel("Value")
plt.ylabel("Frequency")
plt.show()

It looks like either your linewidthwas set to zero or your edgecolorwas set to 'none'. Matplotlib changed the defaults for these in 2.0. Try using:
看起来您的linewidth设置为零或您的edgecolor设置为'none'. Matplotlib 在 2.0 中更改了这些默认值。尝试使用：
plt.hist(gaussian_numbers, edgecolor='black', linewidth=1.2)
