python matplotlib: label in histogram
提问by Edamame
I am using Python (3.4) Jupyter Notebook. I tried to plot a histogram with label using the code below.
我正在使用 Python (3.4) Jupyter Notebook。我尝试使用下面的代码绘制带有标签的直方图。
%matplotlib notebook
import matplotlib.pyplot as plt
import matplotlib
import numpy as np
bins = np.linspace(0, 1.0, 40)
plt.hist(good_tests, bins, alpha = 0.5, color = 'b' , label = 'good')
plt.show()
But the label 'good' doesn't show at all. Did I miss anything? Thanks!
但是“好”标签根本没有显示。我错过了什么吗?谢谢!
