如何更正PlantUML线路径 [英] How to correct PlantUML Line Path

问题描述

我使用以下代码创建了该图.但是正如您所看到的，从(取消订单)和(下订单)到(发布者)的行决定采用一条非常圆滑的路径来获取它们，而不是直接向右再向下再到发布者.我尝试使用"-down"之类的手动方向命令，但似乎都没有帮助.有人知道如何解决这个问题吗?

I created this diagram using the following code. But as you can see, the lines going from (Cancel Order) and (Place Order) to (Publisher) decide to take a terribly rounded path to get their, instead of going straight to the right and then down to publisher. I tried using manual direction commands like "-down" but none of them seemed to help. Does anybody know how to fix this?

这是我的代码.感谢您的帮助.谢谢.

And here is my code. I appreciate any help. Thank you.

    }
}

推荐答案

要使连接在布局中不那么重要，请使用[norank]，例如a -[norank]-> b

To make a connection less important in the layout, use [norank], e.g., a -[norank]-> b
