Plotly Sankey 图：如何设置节点位置，显式 X 和 Y 值不起作用

Question

望大侠指教！当我不指定 X 和 Y 位置时，Sankey 图在形状方面看起来不错，但在垂直排序方面却不行：元素的 vertical/Y 顺序不是我想要的（对于每个 X 位置，垂直排序不同）：

当我设置 pad=100 时，Y 顺序对于每个 X 位置都是正确的，这很奇怪。但是在 pad=1 的情况下，我试图明确设置 X 和 Y 位置，但随后情节在形状方面看起来很奇怪。不知道为什么。有任何想法吗？请参阅下面的示例代码：

})) fig.show()

对于所有 horizontal/X 值 0...6，正确的垂直顺序应该是 br、cl、go、gr、hy。所以它以 0br、0cl、0go、0gr、0hy 开头，然后在它的右边是 1br、1cl、1go、1gr、1hy 等

x 和 y 需要 >0 且 <1。如果 0 或 1 格式不起作用

x = [0, 0, 0, 0, 0, 0.16, 0.16, 0.16, 0.16, 0.16, 0.33, 0.33, 0.33, 0.33, 0.33, 0.5, 0.5, 0.5, 0.5, 0.5, 0.66, 0.66, 0.66, 0.66, 0.66, 0.84, 0.84, 0.84, 0.84, 0.84, 1, 1, 1, 1, 1]
