Plotly :如何在Plotly Express中注释多行？

import plotly.express as px
import plotly.graph_objects as go

fig = go.Figure()

fig = px.scatter(df, x='x', y='y')

annotations = [
    dict(
        x=1,
        y=1,
        xref="x",
        yref="y",
        text="Annotation 1",
        showarrow=True,
        arrowhead=7,
        ax=0,
        ay=-40
    ),
    dict(
        x=2,
        y=2,
        xref="x",
        yref="y",
        text="Annotation 2",
        showarrow=True,
        arrowhead=7,
        ax=0,
        ay=-40
    )
]

for annotation in annotations:
    fig.add_annotation(annotation)

fig.show()
