如何使用 graph_objects 子模块在 plotly sunburst 图表上设置颜色？

Question

如果我使用 plotly express 子模块，我可以通过以下方式创建彩色旭日图：

import plotly.express as px

names = ["Eve", "Cain", "Seth", "Enos", "Noam", "Abel", "Awan", "Enoch", "Azura"]

parents = ["", "Eve", "Eve", "Seth", "Seth", "Eve", "Eve", "Awan", "Eve" ]

values = [10, 14, 12, 10, 2, 6, 6, 4, 4]

color_discrete_sequence = ['#2D5F91', '#FFAA00', '#96BEE6', '#48B7B4', '#E8655F',

                           '#819FBD', '#FFCC66', '#C0D8F0', '#91D4D2', '#F1A39F']

fig = px.sunburst(

    names=names,

    parents=parents,

    values=values,

    color_discrete_sequence = color_discrete_sequence,

)

fig.show()

我想对 plotly 的 graph_objects 做同样的事情。有没有类似的功能？

该版本在官方参考graph_objects中可用。import plotly.graph_objects as gocolor_discrete_sequence = ['', '#FFAA00', '#2D5F91','#819FBD','#819FBD','#91D4D2', '#96BEE6', '#C0D8F0','#E8655F','#F1A39F','#48B7B4']fig =go.Figure(go.Sunburst(    labels=\["Eve", "Cain", "Seth", "Enos", "Noam", "Abel", "Awan", "Enoch", "Azura"\],    parents=\["", "Eve", "Eve", "Seth", "Seth", "Eve", "Eve", "Awan", "Eve" \],    values=\[10, 14, 12, 10, 2, 6, 6, 4, 4\],    marker=dict(colors=color_discrete_sequence)))# Update layout for tight margin# See https://plotly.com/python/creating-and-updating-figures/fig.update_layout(margin = dict(t=0, l=0, r=0, b=0))fig.show()
