Hi,

this is an example:

@startuml
skinparam arrow {
    MessageAlign center
}

|Customer|
|Sales|
:**SEND** report
to customer;
->in big envelop;
|Customer|
:**RECEIVE** report;
-> by mail;
|Sales|
:**RECEIVE** ack;
@enduml


The expected outcome would be that the text is horizontally center above the arrows so it is easier to see the conversation.

Thanks!

Ok, understood. Thanks for the example
One more question: do you expect label to be centered also in the following diagram:
@startuml
skinparam arrow {
    MessageAlign center
}

:**SEND** report
to customer;
->in big envelop;
:**RECEIVE** report;
-> by mail;
:**RECEIVE** ack;
@enduml

Hi,

do you mean the activity labels, like "SEND report"? I don't, this should be a different skin parameter.

Kind regards,
Dries

No, I'm talking about "in big envelop" and "by mail" labels.

I am just wondering if the 3 following diagrams should be rendered differently or not:

@startuml
skinparam arrow {
    MessageAlign center
}

:**SEND** report
to customer;
->in big envelop;
:**RECEIVE** report;
-> by mail;
:**RECEIVE** ack;
@enduml

@startuml
skinparam arrow {
    MessageAlign left
}

:**SEND** report
to customer;
->in big envelop;
:**RECEIVE** report;
-> by mail;
:**RECEIVE** ack;
@enduml

@startuml
skinparam arrow {
    MessageAlign right
}

:**SEND** report
to customer;
->in big envelop;
:**RECEIVE** report;
-> by mail;
:**RECEIVE** ack;
@enduml

Hi,

yes, I would expect 3 different renders. Would that be possible?

Thanks!
