有没有办法改变 plotly.express.sunburst 图中叶子的不透明度？

Question

我不喜欢具有不同不透明度的叶子类别，我找不到更改它的设置。

我找到了this related topic，但我使用的是 plotly.express 而不是 plotly.graph_object。有没有办法改变它，还是我必须尝试将我的 px-figure 更改为 graph_object？ 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

无论你是使用Plotly Express 还是Plotly Graph Objects 来构建你的身材，这都有效：

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

正如相关主题中提到的，透明度可以通过相应的图形对象来控制。

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()
