如何在使用pandas.DataFrame.plot（）构造时间序列图时添加y轴标签

Question

This is my code. I looked at the documentation but didn't find the answer.

 import pandas as pd
 import matplotlib.pyplot as plt
 from datetime import datetime
 avs = pd.read_csv('daily_2004_2014.csv')
 avs = avs.set_index(pd.DatetimeIndex(avs['Date']))
 fig = plt.figure()
 avs.plot()
 plt.show()

Here is the generated image

Answer 1

The plot function returns axes.

axes = avs.plot()

Then you can edit the axes in any way you want. In your case

axes.set_ylabel('Desired Label')
