如何在只有 1 个中心节点的旭日图中正确使用“percentParent”？

Question

所以我正在尝试构建一个 Plotly sunburst 图，percentParent为图中的每个元素显示。这适用于所有元素，除非我只有一个中央节点/环/其他选项（请参见下面的示例）

由于中心节点显然没有父节点，因此它似乎会出错并显示percentParent来自该texttemplate字段的括号内的调用。但是，如果有 2 个（或更多）中央节点，它会自动计算每个中央节点占两者总和的百分比。

我的问题是：当我只有 1 个中心节点时，我如何才能只为中心节点隐藏此字段或使其正确显示“100%”？

示例代码：

import pandas as pd

import plotly.graph_objects as go

df = pd.DataFrame({'node_names': ['Center', 'Yes', 'No'],

                   'node_parent': ['', 'Center', 'Center'],

                   'node_labels': ['Center', 'Center_Yes', 'Center_No'],

                   'node_counts': [1000, 701, 299]})

fig = go.Figure(

       data=go.Sunburst(

        ids=df["node_names"],

        labels=df["node_labels"], 

        parents=df["node_parent"],

        values=df["node_counts"],

        branchvalues="total",

        texttemplate = ('%{label}<br>%{percentParent:.1%}'),

    ),

)

fig.show()
