通过遵循senddex的视频教程，我遇到了错误代码。但是，当我要在ax2上为我的Volume绘制条形图时，它会给我错误代码，如本主题所列。请帮忙。我是Python 0编程新手。

import datetime as dt
import matplotlib.pyplot as plt
from matplotlib import style
import pandas as pd
import pandas_datareader.data as web
style.use('ggplot')

df = pd.read_csv('C:\\Users\\ngjun95\\Downloads\\7120.KL.csv',     parse_dates=True, index_col=0)
df['100ma'] = df['Adj Close'].rolling(window=100, min_periods=0).mean()

print(df.head())

ax1 = plt.subplot2grid((6,1), (0,0), rowspan=5, colspan=1)
ax2 = plt.subplot2grid((6,1), (5,0), rowspan=1, colspan=1, sharex=ax1)

ax1.plot(df.index, df['Adj Close'])
ax1.plot(df.index, df['100ma'])
ax2.bar(df.index, df['Volume'])

plt.show()
