GraphViz nicht respektieren rankdir

Question

So schrieb ich einige Graphviz-Code, um die Untergruppe Gitter einer Ordnung 48 Gruppe mit insgesamt 98 Untergruppen (triviale Gruppe und gesamte Gruppe zählen) zu produzieren. Also habe ich unsichtbare Knoten verwendet, um sie nach der Reihenfolge der Untergruppen zu ordnen, wie ich es bei kleineren Beispielen in der Vergangenheit getan habe, aber dieses Mal passiert etwas Seltsames, es ordnen die Reihenfolge 4 und 8 Untergruppen in der gleichen Zeile und ebenso die Reihenfolge 6 und 12 Untergruppen anordnen, dies trotz expliziter Verknüpfung aller relevanten Ordnungen mit gerichteten Kanten und mit gesetztem rankdir am Anfang. GraphViz Code:

digraph G{ 
rankdir = "BT" ; 
node [shape=plaintext] Order1 -> Order2 -> Order3 -> Order4 -> Order6 -> Order8 -> Order12 -> Order16 -> Order24 -> Order48 [style=invis];

Ich habe noch für die Untergruppe Mitgliedschaft Beziehungen im Code zu setzen, zum Teil, weil ich nicht will, um all diese Arbeit tun, wenn ich dieses Ranking Problem eigentlich beheben kann.

(Ich musste manuell die 4 Leerzeichen zu jeder Zeile hinzufügen, da es nicht kopieren und einfügen würde, schien die Zeilenumbrüche in meinen graphviz Codes als Zeilenumbrüche zu verwechseln, und damit den Codeblock zu beenden, wie kann ich vermeiden diese in der Zukunft?)

Answer 1

Subgroup29 ist gleicher Rang wie beide order4 und Order8 machen order4 effektiv order4 und Order8 Coursing gleichen Rang hat, eines des Ereignisses Umbenennung löst das Problem
