如何在x轴上设置带有日期的图形

Question

我正在创建从QUANDL获取财务数据的代码 问题是我无法按日期设置图表格式。 我上网搜索，发现必须使用matplotlib.dates库 在这里粘贴代码。 谁能帮助我？

我想以这种格式查看日期： 10-10-2018

import pandas as pd
import quandl
import datetime as dt
import numpy as np
#matplotlib
import matplotlib.pyplot as plt 
import matplotlib.dates as mdates
import matplotlib.ticker as mticker

from matplotlib import style


start = dt.datetime(2018, 1, 1)
end = dt.date.today()


s = "AAPL"

#token = ""
#add authtoken = token
df = quandl.get("WIKI/" + s, start_date = start, end_date = end)



# df['10ma'] = df['Close'].rolling(10).mean().shift()
df['10ma'] = df['Close'].rolling(window = 10, min_periods= 0).mean()
df['20ma'] = df['Close'].rolling(window = 20, min_periods= 0).mean()



plt.show()

OUTPUT WITH print(df.head)
