如何使用 plotly.graph_objects 控制 Sunburst 的颜色输入？

Question

我想控制下面旭日图中每个标签的颜色 - 当使用 plotly.graph_objects 而不是 [=25 时=].

请参阅下面 documentation 中的示例：

import plotly.graph_objects as go

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=[  65,    14,     12,     10,     2,      6,      6,      4,       4],
    branchvalues="total",
))
fig.update_layout(margin = dict(t=0, l=0, r=0, b=0))

fig.show()

Answer 1

这将允许访问和控制标记：

import plotly.express as px

greys = px.colors.sequential.Greys
reds = px.colors.sequential.Reds
blues = px.colors.sequential.Blues
greens = px.colors.sequential.Greens
magents = px.colors.sequential.Magenta

fig.data[0].marker.colors = ['', greys[5], reds[5], reds[6], reds[7], 
                             blues[5], greens[5], greens[6], magents[5]]

fig.show()
