questions

1. skinparam spotChar<<metaclass>> M - it works, however, no official documentation found on this skinparam, can i see details on this anywhere but at forum?
2. skinparam spotChar Z - why this param isn't applied on simple class? how can it be done?
3. not skinparam stereotypeCBackgroundColor Red neither skinparam stereotypeCBackgroundColor<<metaclass>> DimGray works but it should according official guide, what have i done wrong here?

Answer 1

Hello G, and all,

Here is an attempt by style:

@startuml
<style>
spotClass {
  BackgroundColor red
}

.metaclass {
  spotClass {
    BackgroundColor DimGray
  }
}
</style>

skinparam class {
    BackgroundColor PaleGreen
    ArrowColor SeaGreen
    BorderColor SpringGreen

    BackgroundColor<<metaclass>> Wheat
    BorderColor<<metaclass>> Tomato
    ArrowColor<<metaclass>> Red
}

'skinparam stereotypeCBackgroundColor Red
'skinparam stereotypeCBackgroundColor<<metaclass>> DimGray
skinparam spotChar Z
skinparam spotChar<<metaclass>> M

class meta <<metaclass>>
class mcls <<metaclass>>
meta "1" *-- "many" Class02 : contains
mcls o-- Class04 : aggregation
@enduml

But that is not conclusive.

@PlantUML: for improvement....

If that can help,
Regards.

so as i see, despite you have tried to mark title chars of metaclasses by gray - you haven't succeeded as well as me

so, finally, it may be treated as a bug since example's compilation result conflicts with official documntation

Yes, there are some issues.

Then awaiting @PlantUML team for their correction.

Thanks a lot.
