Plotly:如何在刻面网格中旋转yaxis标题？

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

fig = make_subplots(rows=1, cols=2)

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

fig.update_layout(
    yaxis=dict(title=dict(text='Y轴标题', standoff=15, font=dict(rotation=45))),
    yaxis2=dict(title=dict(text='Y轴标题', standoff=15, font=dict(rotation=45))),
)

fig.show()
