Hello,
Fork and join nodes can be defined in the following way:
state foo1 <<fork>>
state foo2 <<join>>
However, I could not find how to choose their orientation. All my fork and join nodes end up horizontal, which fits a vertical flow but not an horizontal one.
For instance, when changing ranking direction, it could be useful to also change fork and join nodes orientation:
@startuml
state f <<fork>>
A -> f
f -> B
@enduml
and
@startuml
left to right direction
state f <<fork>>
A --> f
f --> B
@enduml
produce roughly the same diagram (except for arc length), with an horizontal fork, which does not look good.
Thanks,
Fred
