Plotly layer控件:如何在形状前面添加文本

import plotly.graph_objects as go

# 创建图表对象
fig = go.Figure()

# 添加散点图
fig.add_trace(go.Scatter(
    x=[1, 2, 3, 4, 5],
    y=[1, 3, 2, 4, 5],
    mode='markers',
    name='data'
))

# 添加形状
fig.add_shape(
    type='rect',
    x0=2,
    y0=3,
    x1=4,
    y1=5,
    line=dict(color='royalblue', width=2),
    fillcolor='lightskyblue'
)

# 添加文本
fig.add_annotation(
    x=3,
    y=4,
    text='Sample Text',
    showarrow=False,
    font=dict(
        family='Arial',
        size=14,
        color='black'
    )
)

# 设置图表布局
fig.update_layout(
    title='Plot with Text on Shape',
    xaxis_title='X-axis',
    yaxis_title='Y-axis',
    legend=dict(
        x=0,
        y=1,
        traceorder='normal',
        font=dict(
            family='sans-serif',
            size=12,
            color='black'
        ),
        bgcolor='LightSteelBlue',
        bordercolor='Black',
        borderwidth=2
    )
)

# 显示图表
fig.show()
