Plotly设置trendline_scope为trace时分组趋势线失效求助

我能绘制基于所有数据极值的趋势线，但希望为每个按Technology字段（颜色分组）的数据集分别生成趋势线。然而将参数trendline_scope从"overall"修改为"trace"后，结果混乱，达不到预期效果。

fig = px.scatter(df, "Date", y="Number of X", color="Technology", labels={
                     "Date": "Reported Date",
                     "Number of Qubits": "Number of X",
                     "markersize": 50,
                     "s": 50,
                     "title": "X"

                 }, trendline="expanding", trendline_options=dict(function="max"), trendline_scope="trace")
