I want distinct dashed and dotted lines, because of a particular diagramming standard. The graph will be shrunk for publication to something like 1/3 - 1/2 its size. After such shrinking it’s far from clear that the dashed lines are dashed and the dotted lines are dotted:
Is there a way to preserve a line’s dash/dot style under shrinkage? (I’ve experimented a fair bit with penwidth without success so far.)
digraph {
rankdir=LR ranksep=8 node [fontname=“Arial Black”]
A
B
A->B [style=dotted]
A->B [style=dashed]
}
