Summary0000354: sample file causes dotty.lefty to give up on dot (concentrator)
Description



Using dotty version 96c (09-24-96), or as gentoo calls it:
media-gfx/graphviz-1.10 +tcltk



One of the sample files gives:
<CD>
$dotty /usr/share/graphviz/graphs/directed/honda-tokoro.dot
Error: in checkpath, box 3 has LL coord > UR coord
edge 3 from n012 to n011
    (it's part of a concentrator edge)
5 boxes:
0 (37, 84), (93, 95)
1 (-15, 76), (267, 84)
2 (37, 74), (93, 76)
3 (-15, 77), (267, 74)
4 (-15, 64), (122, 77)
start port: (67, 95), tangent angle: 0.000, not constrained
end port: (67, 64), tangent angle: 0.000, not constrained

dotty.lefty: graph that causes dot

dotty.lefty: please fill out a bug report at http://www.research.att.com/~erg/graphviz/bugform.html [^]

Additional Information

[erg] The problem was due to code in dot_sameports which incorrectly
reset a ranks ht2 value. The nodes' y coordinates are not reset. Thus, with
small ranksep as in this graph, an interrank box ends up overlapping the
upper rank, killing the box generating code for spline routing.
