I built a diagram using the draw2d layout manager taken from the GEF
"flow" example. The GraphLayoutManager class uses the
CompoundDirectedGraph.visit() method to perform the layout of the graph.
If I have understood correctly (very poor documentation!) this method puts
the nodes with the same rank horizontally from left to right, while the
nodes with higher rank are aligned vertically as the rank grows. I have a
couple of questions:
1) Is it possible to "traspose" this behaviour: node with the same rank on
vertical and nodes with a higher rank on horizontal?
2) Is it possible to have a mixed behaviour: the whole graph in the
orginal style, while some subgraphs in the "trasposed" one?
Thanks,
Mario

Here's the documentation:

Search the newsgroup for transposing (the entire diagram only) techniques.
