Question

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"];
}

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

Was it helpful?

Solution

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"];
}

Output:

OTHER TIPS

Manual placement of edge labels cannot be done with graphviz.

However, you could use the headlabel, labeldistance and labelangle attributes:

graph triple {
node [shape=box]; User; Object; Tag;
node [shape=diamond,style=filled]; Triple;
    {
        User   -- Triple [headlabel = "1", labeldistance=2.5, labelangle=20];
        Object -- Triple [headlabel = "1", labeldistance=2.5, labelangle=-20];
    }
    {
        rank=same;
        User;
        Object;
    }
    Triple -- Tag [label="n"];
}
