我已經調整了程式碼從這篇文章
我遇到的問題是表之間的關係(線)是跨越表而不是圍繞它們。

這是問題的圖像(可能會更立即清晰)-
我不知道如何阻止線條以目前的方式穿過盒子。我無法在其中找到可阻止此行為的變更值。
另一方面 - 這樣做似乎相當費力,如果其他人有任何關於替代方法的建議,我很高興聽到
謝謝
答案1
這是一種可能的解決方案。樣式zig zag to
設定為預設值 0.5
zig zag to/.default=0.5
此外,one to many
以下兩種樣式也會使用該預設值,這會導致錯誤。該提案刪除了樣式定義zig zag to
中的one to many
,因此不使用
\draw (<start>) to (<end>)
命令中的語法draw
。而是使用那些常見的相對和正交座標繪圖技巧。
\draw (<start>) --++(x,0) |- (<end>);
因為內部標籤(<start>)
和(<end>)
仍然有效,包含局部座標。

答案2
您zig zag to
僅在具有不同座標的點之間才能正常工作x
。
您可以定義另一種樣式,例如,zig zig to
它適用於具有相同點的點x
,並使用它來定義新的one to many bis
。
我one to many
透過新增對 的參數的存取權限進行了更改zig zag to
。這樣邊緣就不會重疊。
