Thank you Nicolas for chasing down this bug. I have made the changes you suggested: http://code.google.com/p/dot2tex/source/detail?r=249 I have to test it some more, but could you try the latest version of dot2tex.py from trunk to verify that it fixes your problem? http://dot2tex.googlecode.com/svn-history/r249/trunk/dot2tex/dot2tex.py > By the way, and purely out of curiosity, is there a reason for having > the "objects" node repeated twice? > I will look into this, It is probably because of the way the graph is represented internally. The parser and data structure is not very elegant. A node can appear multiple times in a graph structure. So instead of keeping track of where every node is in the structure I just append a node statement at the end of the graph when I want to modify attributes. Here is an example: digraph a { subgraph { a -> b; a[label=hello]; } b->d; }; If I want to change the width of node a I do it like this: digraph a { subgraph { a -> b; a[label=hello]; } b->d; a [width=0.4, label=hello]; }; Not very elegant, but as long as it is valid DOT-code Graphviz is happy.
