PlantUml define relative position of components

问题:

I'm actually trying to generate a component diagram with PlantUml. Is it possible to define the relative position of the different components? What want to define is: ComponentB is left from ComponentA. ComponentC is below ComponentA, ...

回答1:

A typical approach is to mark a line as hidden.

One thing to keep in mind is that hidden is only supported for left-to-right ->, and top-to-bottom --> lines, so you need to place the left and right side accordingly (syntax X <[hidden]- Y doesn't seem to be supported).

@startuml
class ComponentA

ComponentB -[hidden]> ComponentA
ComponentA -[hidden]-> ComponentC
