graphviz-固定节点位置 [英] graphviz - fixed node positions

问题描述

我有一个由neato处理的图形，正在为其添加新的边。但是，我不想移动旧的节点。我希望neato可以计算新节点的新位置，而旧节点则位于同一位置。

I have a graph that is processed by neato and I'm adding new edges to it. However, I don't want that the old nodes to be moved. I want that neato computes the new positions of the new nodes and the old nodes stay in the same place.

strict graph {
    node0 [pos="1,2"];
    node1 [pos="2,3"];
}

，然后添加新的边线：

strict graph {
    node0 [pos="1,2"];
    node1 [pos="2,3"];
    node1 -- node2 [len="3"];
    ...
}

我想在旧节点。例如：

strict graph {
    node0 [pos="1,2"];
    node1 [pos="2,3"];
    node2 [pos="3,4"];
    ...
}

我该怎么做？

推荐答案

您可以通过设置节点属性 pin = true 。

You can pin a node's position by setting the node attribute pin=true.

或在pos属性的末尾添加！： pos = 34,12！

Or put a '!' at the end of the pos attribute: pos="34,12!"
