如何在Plotly中为折线图添加95%的置信区间？

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

x = np.linspace(0, 10, 100)
y = np.sin(x)

lower_bound = np.percentile(y, 2.5)
upper_bound = np.percentile(y, 97.5)

fig = go.Figure()
fig.add_trace(go.Scatter(x=x, y=y, mode='lines', name='折线图'))
fig.add_trace(go.Scatter(x=[x[0], x[-1]], y=[lower_bound, lower_bound], mode='lines', name='置信区间下界'))
fig.add_trace(go.Scatter(x=[x[0], x[-1]], y=[upper_bound, upper_bound], mode='lines', name='置信区间上界'))

fig.update_layout(title='折线图 with 95% 置信区间', xaxis_title='X轴', yaxis_title='Y轴')

fig.show()
