如何使用 plotly.graph_objects 控制 Sunburst 的顏色輸入？

Question

我想在下面的森伯斯特圖中控制每個 label 的 colors - 當使用plotly.graph_objects而不是Z2626C5922054DCA時

請參閱以下文檔中的示例：

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

這將允許訪問和控制標記：

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()
