I create dot file by my perl script. Here is subgraphs which contains same node. eg:

subgraph{aa->bb->cc;}
subgraph{dd->bb->ee;}

I know those subgraph use same namespace, so my result output is a mess.

In each subgraph, I can make them unique, like bb and bb_1 below,

subgraph{aa->bb->cc; bb_1->dd;}

but it hard to make all node in all subgraphs unique.

Is there some methods to make each subgraph "strict" or use different namespace?

The label presented for a node is only related to the name of the node if it is not overridden by an explicit references.

For example, you can use "45" [label = "bb"]; "53" [label = "bb"]; to represent two nodes that have the same label.

Then

subgraph{aa->"45"->cc;}
subgraph{dd->"53"->ee;}

will use the internal id of each node to identify it so that you can then reuse the same label in many locations.

gvpack will automatically rename nodes that are in clusters if you use it to put multiple sub-graphs into one graph. See Graph of Graphs in Graphviz for an example.

  • thanks. It seems hard to solve it. So I had added line number to each node, although it is hard work for almost 2 days. – eexpress Aug 22 '13 at 06:28
