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

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。我正在尝试finplot，但是你在网上看到的例子似乎根本不起作用。这招对斯派德没用吗?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:

runfile('C:/Users/billgates/.spyder-py3/untitled8.py', wdir='C:/Users/billgates/.spyder-py3')

忘记创建情节。试试这个。

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