GraphViz/dot 中节点顺序的随机变化

Question

我正在尝试在 GraphViz/dot 中绘制一个小图表。 "Team 1"、"Turnier32" 和 "Team 2" 框应位于同一水平面上。 "Team 1" 指向右侧 "Turnier32"，"Team 2" 指向左侧。我想要相应节点下方的省略号"Name1"、“2015-11-14”和"Name2"。应该只有直的水平和垂直边缘。我目前的做法是：

digraph turnier{
ordering=out ;
subgraph {
    rank=same;
    T1  [shape="box", label="Team 1"];
    TOURNAMENT  [shape="box", label="Turnier32"];
    T2  [shape="box", label="Team 2"];

}
subgraph {
    rank=same;
    N1  [shape="ellipse", label="Name1"];
    DATE  [shape="ellipse", label="2015-11-14"];
    N2  [shape="ellipse", label="Name2"];
}

T1 -> N1 [label="hasName"];
TOURNAMENT -> DATE [label="occuredOnDate"];
T2 -> N2 [label="hasName"];
T1 -> TOURNAMENT [label="attended"];
T2 -> TOURNAMENT [label="attended"];
}

GraphViz 将 T1、TOURNAMENT 和 T2 重新排序为 T1、T2、TOURNAMENT，这不是我想要的。如果我删除了最后两条边，则顺序正确。

Answer 1

只需添加到您的最后一行 constraint=false:

T2 -> TOURNAMENT [label="attended", constraint=false];
