如何使用plotly定义子图的布局

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

# 创建子图布局
fig = make_subplots(rows=2, cols=2)

# 添加子图
fig.add_trace(go.Scatter(x=[1, 2, 3], y=[4, 5, 6], name='Plot 1'), row=1, col=1)
fig.add_trace(go.Bar(x=[1, 2, 3], y=[7, 8, 9], name='Plot 2'), row=1, col=2)
fig.add_trace(go.Pie(labels=['A', 'B', 'C'], values=[10, 20, 30], name='Plot 3'), row=2, col=1)
fig.add_trace(go.Line(x=[1, 2, 3], y=[11, 12, 13], name='Plot 4'), row=2, col=2)

# 设置子图布局参数
fig.update_layout(height=600, width=800, title_text="Subplots Example")

# 显示图表
fig.show()
