更改绘图标签的颜色

Question

所以我有一个非常基本的 Sankey 图，与文档中的非常相似：

import plotly.graph_objects as go

fig = go.Figure(data=[go.Sankey(
    node = dict(
      pad = 15,
      thickness = 20,
      line = dict(color = "black", width = 0.5),
      label = ["A1", "A2", "B1", "B2", "C1", "C2"],
      color = "blue"
    ),
    link = dict(
      source = [0, 1, 0, 2, 3, 3], # indices correspond to labels, eg A1, A2, A1, B1, ...
      target = [2, 3, 3, 4, 4, 5],
      value = [8, 4, 2, 8, 4, 2]
  ))])

fig.update_layout(title_text="Basic Sankey Diagram", font_size=10)
fig.show()

我想做的是改变标签的颜色(A1,A2..)。我该怎么做？

Answer 1

仔细阅读reference documentation:)

fig.update_traces(textfont_color=<VALUE>, selector=dict(type='sankey'))

这应该设置节点标签的字体颜色
