Plotly :将图例添加到子图

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

# 创建一个包含两个子图的图表
fig = make_subplots(rows=1, cols=2, subplot_titles=("Subplot 1", "Subplot 2"))

# 添加第一个子图
fig.add_trace(
    go.Scatter(x=[1, 2, 3], y=[4, 5, 6], mode='markers', name='Series 1'),
    row=1, col=1
)

# 添加第二个子图
fig.add_trace(
    go.Scatter(x=[1, 2, 3], y=[6, 5, 4], mode='lines', name='Series 2'),
    row=1, col=2
)

# 更新布局，设置图例位置
fig.update_layout(legend_title_text="Legend", legend=dict(orientation="h", yanchor="bottom", y=1.02, xanchor="right", x=1))

# 显示图表
fig.show()

fig.update_layout(legend_title_text="Legend", legend=dict(orientation="h", yanchor="bottom", y=1.02, xanchor="right", x=1))

fig = make_subplots(rows=1, cols=2, subplot_titles=("Subplot 1", "Subplot 2"), shared_xaxes=True, shared_yaxes=True)
