Matplotlib only graph dates in the DataFrame?

Question

How do I plot the graph with only the dates in my DataFrame? I'm getting weekends and holidays which are not in the DataFrame.

import matplotlib.pyplot as plt
import pandas_datareader.data as web 
import datetime
data = web.DataReader("SPY",'yahoo', '2019-02-12','2019-02-19')
data.Close.plot()
plt.show()

Answer 1

import pandas_datareader.data as web 
import datetime
df = web.DataReader('SPY', 'yahoo', '2019-02-12','2019-02-19')
df = df.reset_index()
df['Date'] = df['Date'].astype(str)

DataFrame

情节

ax = df['Close'].plot(marker='o')
ax.set_xticks(df.index)
ax.set_xticklabels(df['Date']);
