I have a state diagram.


State1 -down->  State2: goes to

now I will get in the png-picture - pipe symbol meaning the down arrow:

state1 | goes to state2

Can I have

state1 goes to | state2

I have tried and searched but without success.

I do not mean notes. I know it is possible with notes.

Thank you in advance.

Best regrads,

Unfortunatly, PlantUML is using Graphviz/Dot for that.

And I don't think that it is possible to change label position in edges.
(More info on )

digraph G {
    a -> b [label="foo"]

If someone succeeds in changing the label with Graphviz/Dot, please post here.

maybe you could add functionality to use headlabel/labeldistance/labelangle?

Thanks for your idea.
Unfortunatly, labelangle does not apply to label, only to headlabel/taillabel.
( )

See here an example:

digraph G {
    a -> b [label="foo", headlabel = "1", labelangle=20]
    a -> c [label="foo", headlabel = "1", labelangle=-20]

A trick could indeed to use headlabel and to automatically compute a "labeldistance".
It's possible to do that on manual edited dot file, but on an generated file, that's another story.
So we are still looking for something here.

according to this stackoverflow contribution

it seems possible to add this using the xlabel feature of current graphviz

essential parts copied from the reference:
Graphviz Graph with arrow-text-anchor changed

digraph {

    0:sw -> 1:nw [ dir=forward, xlabel="  (1, 0)  "];
    0 -> 1 [dir=none];
    1:ne -> 0:se [ dir=backward, xlabel= "  (0, -1)  "];

you need graphviz version >2.29 to use xlabel.

This would be great if it were possible (start using xlabel).
