Graphviz如何修复集群的x

Question

​

​

目前，我正在尝试修复集群的x，因为它们似乎在四处移动，创建了一个杂乱的图。所有的子图都有rank=same和newrank=true。仅对于从一个簇到另一个簇的边，constraint值设置为true。

我尝试了http://martin-loetzsch.de/S-DOT/constraint.html中的许多选项，但都不能正常工作。有人知道为什么子图会像上面那样水平移动吗？

我还没有找到一种简单的方法来轻松地移动集群。这是一个可以做你想做的(我认为)并且不需要太多修改源码的kludge：

用/*注释掉你所有的边... */ (这些边导致了末尾的这些线条(以产生你想要的对齐方式)：

switch_1 -> switch_2 -> watson style=invis watson -> {azure_1 tsX} style=invis

1. 针对输出文件格式运行dot with -Tdot
2. 编辑输出文件并重新插入您注释掉的边
3. 运行

with -n选项以固定节点和集群并添加边

neato -n -Tpng mylile.dot >myfile.png
