0002601: spline option for dot not working properly in simple graphs with HTML-like records
I have a simple graph with HTML-like records. The edges between ports in the same node are always what you would expect with the splines parameter set to "spline", no matter what the parameter is actually set to (except that setting it to "curved" leads to an error, something I reported in a separate issue).
Try the following example. Try setting the splines parameter to "polyline" and you will see that the type of edge you get is not a polyline. The "ortho" setting does not generate a reasonable figure, but that is a know issue.

digraph G {
rankdir=BT
node [shape=plaintext]
splines = line

a [label=<
  <TABLE BORDER="0" CELLBORDER="1" CELLSPACING="0">
  <TR><TD border="0"> </TD>
    <TD PORT="6">z</TD>
    <TD border="0"> </TD>
  </TR>
  <TR> <TD ROWSPAN="4" COLSPAN="3">
B
</TD> </TR>
  <TR> <TD border="0"> </TD> </TR>
  <TR><TD PORT="5">y</TD></TR>
  <TR> <TD border="0"> </TD></TR>
  <TR><TD border="0"> </TD>
    <TD PORT="4">x</TD>
  <TD border="0"> </TD>
  </TR>
  </TABLE>>];


a:5 -> a:6 ;
a:4 -> a:6 ;
}


 
neato and fdp have the same issue, but the "curved" setting does not cause an error.
