Re: [Haskell-cafe] graphviz: dotizeGraph and graphToGraph not adding positions

My understanding of the documentation for Data.GraphViz.dotizeGraph and graphToGraph is that they should add position attributes to a graph. But they always seem to return graphs with empty attribute lists. What am I doing wrong in the following tiny example?

...

dotizeGraph nonClusteredParams (insNode (0, "Blah") $ empty :: Gr String ())

0:([],"Blah")->[]

I expected the first list to contain at least a Pos attribute.

I have written a wrapper around /usr/share/dot which shows the program is outputting positional information.

OK, a bug has crept in, I'll have a look at it next week. -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
