KeyError：“在轴中找不到[['Symbol“'交易量BTC''交易量USDT']”

Question

大家好，我在python中遇到此错误。

series.trendline = Trendline(dispEq = True, dispRSqr=True)
# series.trendline.dispEq.position = "tr"
series.trendline.dispEq = Layout(
    manualLayout=ManualLayout(
    x=50, y=50
    )
)

KeyError：“在轴上找不到[[Symbol]'Volume BTC''Volume USDT']“

我该如何解决..

我的文件是

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt


btcData=pd.read_csv("Binance_BTCUSDT_d.csv")
btcData=btcData.drop(['Symbol', 'Volume BTC', 'Volume USDT'])
btcData.head()

fig,ax=plt.subplots(figsize=(15,10))
btcClose=btcData['Close']
plt.plot(btcClose)
