使节点不影响图形布局

Question

我正在尝试在不影响连接节点定位的情况下制作节点。当我绘制图形时，它将父节点置于子节点之间；这造成了交错效应。如何使故障节点不影响其他节点的布局？我已经把线条画直了，就像他们想要的照片一样，但它仍然有交错的布局。

当前样式：

想要的风格：

我无法渲染你的代码来实现你的图片，但我将要建议的技术无论如何都应该有效。

我编写了一个类似的基本示例代码：

digraph {
    node [shape=rect]

    a -> b -> c -> d -> e -> f
    success [shape=oval]
    f -> success
    {
        rank=max
        failure [shape=oval]
    }
    {a b c d e f} -> failure
}

转载您的问题后得到以下图片：

第一个可能的解决方案可能是将constraint=false属性添加到通往falure节点的边缘。此属性就是这样做的 - 防止边缘影响布局。

digraph {
    node [shape=rect]

    a -> b -> c -> d -> e -> f
    success [shape=oval]
    f -> success
    {
        rank=max
        failure [shape=oval]
    }
    {a b c d e f} -> failure [constraint=false]
}

结果：

第二种可能的解决方案 是增加需要保持笔直的边缘的 weight 属性。权重较高的边往往比其他边更短更直：

digraph {
    node [shape=rect]

    a -> b -> c -> d -> e -> f [weight=10]
    success [shape=oval]
    f -> success
    {
        rank=max
        failure [shape=oval]
    }
    {a b c d e f} -> failure
}

结果：
