在不考虑周末的情况下，如何确保日期显示在Yahoo Finance / Google Finance中？

Question

我目前正在使用Alpha-Vantage以1分钟的间隔获取财务数据。

amd=ts.get_intraday(symbol=symbol, outputsize='full', interval=interval)
amd=pd.DataFrame(amd[0])
amd.drop(amd.index[-1])

我得到了以下输出

...

如你所见，日期从2月28日跳到3月2日，这是理所当然的。但是，在matplotlib中绘制它时...

amd['4. close'].plot()

plt.title('AMD')
plt.show() 

...我得到了下面的图，其中mathplotlib compensates for the lack of data in weekends and at closed market通过从一个数据点到另一个数据点绘制一条直线。

如何获得类似于雅虎财经或谷歌财经股票图表的结果，其中忽略了未命中的数据(as in this example

Answer 1

就用这个吧。好了。

import pandas as pd
import datetime
import pandas_datareader.data as web
start=datetime.datetime(2019,3,12)
end=datetime.datetime(2020,3,12)
df=web.DataReader('IBM','yahoo',start,end)
print(df)

结果：
