有没有办法更改plotly.express.sunburst图形中树叶的不透明度？

Question

我不喜欢叶子类别有不同的不透明度，我找不到改变它的设置

我找到了this related topic，但我使用的是plotly.express而不是plotly.graph\u对象。有没有办法改变它，或者我必须试着把我的px图形变成一个graph_对象？ example image

import plotly.express as px
data = dict(
    character=["Eve", "Cain", "Seth", "Enos", "Noam", "Abel", "Awan", "Enoch", "Azura"],
    parent=["", "Eve", "Eve", "Seth", "Seth", "Eve", "Eve", "Awan", "Eve" ],
    value=[10, 14, 12, 10, 2, 6, 6, 4, 4])

fig =px.sunburst(
    data,
    names='character',
    parents='parent',
    values='value',
)
fig.show()

Answer 1

无论您是使用Plotly Express还是Plotly Graph Objects构建您的体形，这都是有效的：

fig.update_traces(leaf=dict(opacity = 1))

完整代码：

import plotly.express as px
data = dict(
    character=["Eve", "Cain", "Seth", "Enos", "Noam", "Abel", "Awan", "Enoch", "Azura"],
    parent=["", "Eve", "Eve", "Seth", "Seth", "Eve", "Eve", "Awan", "Eve" ],
    value=[10, 14, 12, 10, 2, 6, 6, 4, 4])

fig =px.sunburst(
    data,
    names='character',
    parents='parent',
    values='value',
)

fig.update_traces(leaf=dict(opacity = 1))

fig.show()

Answer 2

如相关主题中所述，透明度可以通过相应的图形对象进行控制

import plotly.graph_objects as go

fig =go.Figure(go.Sunburst(
    labels=data['character'],
    parents=data['parent'],
    values=[10, 14, 12, 10, 2, 6, 6, 4, 4],
    leaf=dict(opacity=1),
))

fig.update_layout(margin = dict(t=0, l=0, r=0, b=0))

fig.show()
