Re^2: graphViz and compass pointed labels

> headlabel, taillabel and labeldistance, port_label_distance, labelangle

None of these directly address my problem. The symptom is:

Since I have many edges that may go into the same port/label in a target node, each edge appears as a unique line that comes from 'wherever' the source node is into the center of the target node. ie.

   +---+        +---+
   | A |        | B |
   +---+        +---+
     \           /
      \         /
    target   target
        \    /
       +-----+
       |  D  |
       +-----+
         /
      target
       /
      /
   +---+
   | C |
   +---+

What I would prefer is that all edges that target the same label should enter the target node at the same spot. That also means that it should re-orient the nodes to minimize any overlap accordingly, In my simple example above, that effectively means that all the source nodes should end up on 'the same side as the target node. ie. something like this:

   +---+ +---+ +---+
   | C | | B | | C |
   +---+ +---+ +---+
      \    |    /
       \   |   /
        \  |  /
         target
          \|/
         +---+
         | D |
         +---+

Or evern more cleanly... allow the target label to exist 'within' the target node rather than on the 'edge'. Ie. the port is labeled, rather than each and every edge-endpoint.

    +---+ +---+ +---+
    | A | | B | | C |
    +---+ +---+ +---+
       \    |    /
        \   |   /
         \  |  /
          \ | /
           \|/
       +---------+
       | target  |
       |         |
       |    D    |
       |         |
       +---------+

It would make for 'cleaner' graphs!

Here is hack, uses separate compass_pt argument for $to because i don't grok dot :) It seems to work Read more... (12 kB)	[reply] [d/l]

None of these directly address my problem. I don't pretend to understand your problem, but I don't even know which GraphViz program you're using :) I suggest you create a tiny program and try the debug method to figure out where to patch GraphViz.pm.	[reply]


Come for the quick hacks, stay for the epiphanies.
