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.
Solution:1
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:
Solution:2
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"]; } Output:
