如何在plotly中将规格用于子图？

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

# 创建一个包含2行2列的子图
fig = make_subplots(rows=2, cols=2, specs=[[{'type': 'scatter'}, {'type': 'scatter'}],
                                           [{'type': 'bar'}, {'type': 'scatter'}]])

# 向子图中添加数据和布局
fig.add_trace(go.Scatter(x=[1, 2, 3], y=[4, 5, 6], mode='markers'), row=1, col=1)
fig.add_trace(go.Scatter(x=[1, 2, 3], y=[2, 4, 6], mode='lines'), row=1, col=2)
fig.add_trace(go.Bar(x=[1, 2, 3], y=[10, 20, 30]), row=2, col=1)
fig.add_trace(go.Scatter(x=[1, 2, 3], y=[5, 10, 15], mode='lines'), row=2, col=2)

# 设置子图的标题和整体布局
fig.update_layout(title='Subplots Example', height=600, width=800)

# 显示图表
fig.show()
