【Python】股票价格与交易量分析代码

1.各股价格对比

import pandas as pd
from pandas_datareader import data
import matplotlib.pyplot as plt
start_data='2017-01-01'
end_data='2018-10-01'
plt.subplots(figsize=(10, 10))
plt.plot(GOOGDf['Close'],label='Google',color='blue')
plt.plot(AMZNDf['Close'],label='Amazon',color='r')
plt.plot(FBDf['Close'],label='Facebook',color='k')
plt.plot(TENDf['Close'],label='Tencent',color='g')
plt.title('Comparison of GOOG & AMZN & FB & TEN')
plt.xlabel('Date')
plt.ylabel('Close')
plt.legend() #显示标签
plt.grid(True)
plt.show()

2.同时查看股票价格及交易量

import matplotlib.pyplot as plt
import pandas_datareader.data as getData
df=getData.DataReader("GOOG",'yahoo')
plots=df[['Close','Volume']].plot(subplots=True,figsize=(10,10))
plt.show()
