Plotly 是否與 function 類似 matplotlib fill_between

Question

我正在將一些 matplotlib 代碼轉換為 Plotly。

Plotly 有沒有類似於 matplotlib fill_between

要轉換的代碼

    #   ax.fill_between(fcst_t, fcst['yhat_lower'], fcst['yhat_upper'],
    #   
                 color='#0072B2', alpha=0.2, label='Uncertainty interval')

我可以設法做類似下面的事情，但我想用特定的顏色填充這兩條線之間的區域。

    fig.add_trace(
           go.Scatter(x=fcst_t,y=forecast['yhat_lower'],fillcolor='grey',mode='lines+markers',name="yhat_lower"),
            row=1,col=1
    )

    fig.add_trace(
           go.Scatter(x=fcst_t,y=forecast['yhat_upper'],fillcolor='grey',mode='lines+markers',name="yhat_upper"),
            row=1,col=1
    )

go.Scatter有一個fill關鍵字，可以用來控制填充行為。 您可以在此文檔頁面或鍵入help(go.Scatter)閱讀更多內容。

import plotly.graph_objects as go
import numpy as np

x = np.linspace(0, 10, 100)
y1 = np.sin(x) + 2
y2 = np.sin(x / 2) + 8
fig = go.Figure([
    go.Scatter(x=x, y=y1),
    # fill between the endpoints of this trace and the endpoints of the trace before it
    go.Scatter(x=x, y=y2, fill="tonextx"),
])
fig

如果兩條線的點數不同，填充也應該有效！
