我是 Python 新手,更具体地说是 Alpha Vantage。我的问题是我的代码正在收集股票的数据,但它没有绘制图表。我用 3.7 python 在我的 cmd 上运行了这段代码,并且已经更新了我所有的包。我听说人们在使用 matplotlib 和 3.7 版本的 python 时遇到问题,但我真的很想弄清楚这个 API。这是我下面的代码:
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)
在为符号名称输入 MSFT 后,我在我的 cmd 上得到了这个响应......这意味着我正在从 API 中提取,但 data['close'] 函数无法与 PANDAS 一起正常工作
