Span a note across the width of a group in sequence diagrams

Question

Hi, it would be helpfull to be able to have notes that span across the width of, all kinds of, groups.

That would mean a notation like:

note across group: 

I am aware this can be done manually by specifying note over pariticipant#1, pariticipant#X.... but this adds overhead and complexity especially when you reorder the participants

Hello I.,

See similar request here:

• https://forum.plantuml.net/9738/sequence-diagram-note-over-all

And the solution:

note across: note_description

See also doc. here:

Enjoy,

Ah ok: that is already done for all participants.

But not yet for group...

Then your wanted feature remains...

Appears to be possible

@startuml
Alice -> Bob: Authentication Request
Bob -> Alice: Authentication Failure
group My own label [My own label 2]
note across: note across group
Alice -> Log : Log attack start
loop 1000 times
Alice -> Bob: DNS Attack
end
Alice -> Log : Log attack end
end

Hello D,

Thanks for your workaround.

But if you create a new participant like Eve:

• How to have a note only across group, (not including Eve!)?

@startuml
Alice -> Bob: Authentication Request
Bob -> Alice: Authentication Failure
group My own label [My own label 2]
note across: note across group
Alice -> Log : Log attack start
loop 1000 times
Alice -> Bob: DNS Attack
end
Alice -> Log : Log attack end
end
Bob -> Eve
