Graphviz:将边缘标签放在另一侧 [英] Graphviz: Place edge label on the other side

问题描述

这可能与如何将边缘标签放到graphviz的边缘:我有以下图形，可以使用命令dot -Teps g.dot > g.eps进行可视化:

This may be related to How to place edge labels ON edge in graphviz: I have the following graph, which I visualize using the command dot -Teps g.dot > g.eps:

graph triple {
    node [shape=box]; User; Object; Tag;
    node [shape=diamond,style=filled]; Triple;
    {
        User -- Triple [label = "1"];
        Object -- Triple [label = "1"];
    }
    {
        rank=same;
        User;
        Object;
    }
    Triple -- Tag [label="n"];
}

我希望通过在图形的左侧将User和Triple之间放置标签，使结果更加对称.

I would like the result to be more symmetric by putting the label between User and Triple on the left side of the graph.

推荐答案

这是使用splines=false和双边的第二种解决方法:

And here's the second workaround using splines=false and double edges:

graph {
splines=false;
node [shape=box]; User; Object; Tag;
node [shape=diamond,style=filled]; Triple;
    {
        User   -- Triple [label = "1"];
        User   -- Triple [label = ""];
        Object -- Triple [label = ""];
        Object -- Triple [label = "1"];
    }
    {
        rank=same;
        User;
        Object;
    }
    Triple -- Tag [label="n"];
}

输出:
