Python Plotly Sankey 图：链接通过节点而不是围绕它们

如何解决Python Plotly Sankey 图：链接通过节点而不是围绕它们

我创建的 Sankey 有一个输出链接通过它的源节点，一个输入链接通过它的目标节点，而不是周围。见下图。从节点 J 到节点 D 的链接是通过而不是绕过。

Sankey with undesired behaviour

使用的代码：

import plotly.graph_objects as go

sankey_data = go.Sankey(link={'source': [0,2,3,1,7,8,9,4,4],'target': [2,5,6,6],'value': [11.166194444444445,32.256194444444446,6.79125,26.99652777777778,0.0,5.691416666666667,11.968416666666666,3.42275,7.648416666666666,11.166194444444445,3.783611111111111,5.071111111111112,1.90625,2.6694444444444443,0.5596944444444445,0.1471944444444444,0.1175,0.1815277777777777,1.29711066,0.140356724,1.879150455,4.076354915,6.966262547,0.00140078,0.00166618,0.00408898,0.053322942,0.659548282,1.29570988,0.138690544,1.875061475,4.023031973,6.306714265,0.057285199,0.00023536,1.00432117,1.00432117],'label': ['Biomassa','Fossiel','Metalen','Mineralen','Onbekend/Gemengd','Biomassa','Onbekend/Gemengd']},node={'label': ['A','B','C','D','E','F','G','H','I','J'],'x': [0.0,0.2,0.4,0.9,0.5,0.8,0.9],'y': [0.0,0.1,0.6,0.95],'pad': 10},arrangement='snap')

fig = go.Figure(sankey_data)
fig.show()

作为参考，这个玩具示例显示了正确的行为：

import plotly.graph_objects as go

fig = go.Figure(go.Sankey(
    arrangement = "snap",node = {
        "label": ["A","B","C","D","E","F"],"x": [0.2,0.7,0.3,0.5],"y": [0.7,0.3],'pad':10},# 10 Pixels
    link = {
        "source": [0,5],"target": [5,3],"value": [1,3]}))

fig.show()

Sankey with desired behaviour

例如，从节点 F 到节点 A 的链接显示了我想要的内容。

据我所知，我的代码与玩具示例大致相同，除了实际值。我还检查了我自己代码中的相关链接是否朝着正确的方向流动（源 = J，目标 = D）。我还调整了节点位置，以确保链接有足够的空间来完成它的工作。更改排列设置也不起作用，我在文档中找不到任何明确的链接行为设置。我认为这可能是一些版本问题，也许求解器已经改变，但两个示例 Sankeys 来自同一个笔记本。

我没有想法，所以任何帮助将不胜感激！
