如何使用自定义按钮修改Plotly图的布局

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

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

button1 = dict(method='relayout', args=['xaxis.title.text', '新标题1'])
button2 = dict(method='relayout', args=['xaxis.title.text', '新标题2'])

fig.update_layout(
    updatemenus=[
        dict(
            buttons=[
                dict(label="按钮1", method="relayout", args=[...]),
                dict(label="按钮2", method="relayout", args=[...]),
                ...
            ],
            direction="down",
            pad={"r": 10, "t": 10},
            showactive=True,
            x=0.1,
            xanchor="left",
            y=1.1,
            yanchor="top"
        ),
    ]
)

fig.show()
