@enduml

我想problem放在左边solution，所以我认为problem -right-> solution可以，但事实证明既不-left- 也不-right-能做任何改变，problem反正是右边，我该怎么办？

SO告诉我大部分代码都在那里，所以在这里我不得不胡说八道，我认为PlantUML的布局控制很糟糕，没人知道开发过程中的结果是什么，好吧，就是这样

当我以其他顺序定义矩形并调整问题和 flow_3 之间的箭头时，它看起来不错。

@startuml
rectangle "System Architecture" as map {

    rectangle "Soluation" as solution {
        rectangle "Flow 1" as flow_1 {

        }
        rectangle "Flow 2" as flow_2 {

        }
        flow_1 -down[hidden]-> flow_2
        rectangle "Flow 3" as flow_3 {

        }
        flow_2 -down[hidden]-> flow_3
        rectangle "Flow ..." as flow_ {

        }
        flow_3 -down[hidden]-> flow_
        rectangle "Flow N" as flow_n {

        }
        flow_ -down[hidden]-> flow_n

    }
    rectangle "Problem" as problem {
        rectangle "Quantity" as quantity {

        }

    }
    problem -[hidden]> flow_3
}
