Use the edge attribute statement, as stated in the DOT Language documentation. digraph graphname { subgraph clusterA { node [shape=plaintext,style=filled]; edge [arrowhead=normal,arrowtail=dot]; 1 -> 2 ; 2 -> 3 -> X2 -> 5; 6; 7; label = “A”; color=blue } }
You should just use: A -> B [dir=both]
Well, as with most questions…soon after I posted the I figured out the answer. I needed to add graph [overlap=false]; at the top of the file. Do it like this: graph g { overlap = false; node [shape=record,height=.1]; /* … */ }
Load the file with pydot.graph_from_dot_file to get a pydot.Dot class instance. Then write it to a PNG file with the write_png method. import pydot (graph,) = pydot.graph_from_dot_file(‘somefile.dot’) graph.write_png(‘somefile.png’)
Leaving the rank empty or using rank=same are used far more often. These other four are usually only used in special circumstances. When used alone, min and source have the same function: putting all those nodes on the minimum rank (the top row of a TB graph). The difference between them is that min will … Read more
Two useful techniques for reproducing graph layouts are: Invisible nodes Rank constraints Here’s a quick try for the top nodes: digraph g{ ranksep=0.2; node[shape=box3d, width=2.3, height=0.6, fontname=”Arial”]; n1[label=”Incident Commander”]; n2[label=”Public Information\nOfficer”]; n3[label=”Liaison Officer”]; n4[label=”Safety Officer”]; n5[label=”Operations Section”]; n6[label=”Planning Section”]; n7[label=”Logistics Section”]; n8[label=”Finance/Admin. Section”]; node[shape=none, width=0, height=0, label=””]; edge[dir=none]; n1 -> p1 -> p2 -> p3; … Read more
Graphviz, dot, ortho plots do not respect ports
If this was headlabel or taillabel, you could try setting labeldistance to zero to force the label to be drawn on the edge, but as I understand, you are referring to edge label (the one on the middle of the edge). Documentation quite clearly states that labeldistance only affects headlabel and taillabel labels, but you … Read more
Try the following: digraph simpsons { subgraph Generation0 { rank = same Abraham [shape = box, color = blue] Mona [shape = box, color = pink] AbrahamAndMona [shape = point] Abraham -> AbrahamAndMona [dir = none] AbrahamAndMona -> Mona [dir = none] Clancy [shape = box, color = blue] Jackeline [shape = box, color = … Read more
From the DOT Guide http://www.graphviz.org/pdf/dotguide.pdf on page 4 it says the following: When drawn, a node’s actual size is the greater of the requested size and the area needed for its text label, unless fixedsize=true, in which case the width and height values are enforced. Thus you simply need to add fixedsize=true to your code
