如何在Spyder 4+IDE上使用finplot和yfinance绘制烛台图表？

Question

我是一个python新手，试图学习在Spyder IDE上用yfinance绘制一些烛台图表。我正在尝试finplot，但您在web上看到的示例似乎根本不起作用。这对Spyder不起作用吗？我错过了什么

首先，从python控制台安装finplot和yfinance

pip install finplot
pip install yfinance

然后在spyder IDE中，复制并粘贴示例代码：

import finplot as fplt
import yfinance
df = yfinance.download('AAPL')
fplt.candlestick_ochl(df[['Open', 'Close', 'High', 'Low']])
fplt.show()

结果:

恶心。做

d = df[['Open', 'Close', 'High', 'Low']].reset_index(drop=True)
fplt.candlestick_ochl(d)
