How to make multiple sequence diagrams in single page

I wonder if there is any way to make a plantuml two sequence diagram in single page side by side. I want to keep the same actor names in both diagram. Currently if I do something like below, it automatically combined into single sequence diagram.

@startuml
Bob -> Alice : hello
@enduml

@startuml
Bob -> Mark : Hi
@enduml

sample

But expected two sequence side by side

Solution

  • newpage: The newpage keyword is used to split a diagram into several images.

    @startuml

header SayHello
footer Page %page% of %lastpage%

Bob -> Alice : hello

newpage last page

Bob -> Mark : Hi

@enduml

    Result:

    Reference

    You also could define a variable like "PAGE_SETTING" to decide whether on or off it.

    @startuml

' seton demo
!define PAGE_SETTING newpage

header SayHello
footer Page %page% of %lastpage%

Bob -> Alice : hello

PAGE_SETTING

Bob -> Mark : Hi

@enduml

    Result:
