我是Python的新手,更具体地说,Alpha Vantage。我的问题是我的代码正在收集股票数据,但没有绘制图形。我使用3.7 python在我的cmd上运行了这段代码,并且已经更新了所有软件包。我听说人们在使用matplotlib和3.7版本的python时遇到问题,但是我真的很想弄清楚这个API。这是我的代码如下:
from alpha_vantage.timeseries
import TimeSeries
import matplotlib.pyplot as plt
import sys
def stockchart(symbol):
ts = TimeSeries(key='1ORS1XLM1YK1GK9Y', output_format='pandas')
data, meta_data = ts.get_intraday(symbol=symbol, interval='1min', outputsize='full')
print (data)
data['close'].plot()
plt.title('Stock chart')
plt.show()
symbol=input("Enter symbol name:") stockchart(symbol)
在输入MSFT作为符号名称后,我在cmd上得到了响应...这意味着我正在从API中提取数据,但data ['close']函数在PANDAS上无法正常工作
1. open 2. high 3. low 4. close 5. volume

KeyError: 'close'
答案 0 :(得分:0)
我遇到了同样的问题。
请注意这一行,其中包含列的名称:
1. open 2. high 3. low 4. close 5. volume
因此,用列名称更改此行:例如:
data['close'].plot()
更改为data['4. close'].plot()
