Description



Hi,



The following description will produce semantical different
outputs, regarding if node "R" is put into the rank=source
block or not. In the first case (node "R" is out of the block)
a correct diagramm is renderd, but the label is missanligned.
But if once put "R" into the first block to ensure an special
ranking (as schown below), the position of the label is now
correct, but the direction of the arrow changed, so
that "P" is a successor of "R".



Digraph g {
  dpi=150.0;
  nodesep=0.5;
  ranksep=0.75;



{rank=source;
  R;
  P;
}



{rank=sink;
  Q;
}
  P->R [constraint=false, arrowhead=vee, label="O"];
  R->Q [arrowhead=onormal];
}
Additional Information

[erg]
The flat edge problem has been fixed.

The other problem (misplaced edge label) is still there. \<A HREF="b2012.gv"\>Here\</A\>
is a small graph exhibiting the problem. The output file shows the problem.
Note that both constraint=false and rank=source are necessary to cause the problem.
TagsNo tags attached.

testing on 7sp1 2.33.20130905

edge P->R fails to show "label" when edge is Vertical but does show when edge is Horizontal.

edge P->R will show "xlabel" in either orientation.
