如何在单个x值Python中对观测值进行Plotly平均

import plotly.graph_objects as go
import numpy as np

x = np.array([1, 2, 3, 4, 5])
y = np.array([10, 20, 30, 40, 50])

average = np.mean(y)

fig = go.Figure()

fig.add_trace(go.Scatter(x=x, y=y, mode='markers', name='Observations'))
fig.add_trace(go.Scatter(x=[x[0], x[-1]], y=[average, average], mode='lines', name='Average'))

fig.update_layout(title='Plotly平均值示例', xaxis_title='x值', yaxis_title='观测值')

fig.show()
