如何使用Plotly创建垂直滚动条？

import plotly.graph_objects as go
from plotly.subplots import make_subplots

fig = make_subplots(rows=2, cols=1, vertical_spacing=0.1, subplot_titles=("图表1", "图表2"))

fig.add_trace(go.Scatter(x=[1, 2, 3], y=[4, 5, 6], name="数据1"), row=1, col=1)
fig.add_trace(go.Scatter(x=[1, 2, 3], y=[7, 8, 9], name="数据2"), row=2, col=1)

fig.update_layout(height=600, width=400, title_text="垂直滚动条图表", showlegend=True, updatemenus=[{"type": "buttons", "buttons": [{"label": "播放", "method": "animate", "args": [None, {"frame": {"duration": 500, "redraw": True}, "fromcurrent": True, "transition": {"duration": 300, "easing": "quadratic-in-out"}}]}]}])

fig.show()
