使用 pgfplots 疊加在「分組堆疊」長條圖上的折線圖？

我需要在堆疊的分組長條圖上疊加折線圖（類似於回答問題：長條圖中的兩個層級標籤）。

我必須為每個組疊加一個折線圖（它在組的邊界處斷開）。例如：第一條線圖連接S1、S2、S3；第二個連接S4、S5、S6；最後一個連接S7、S8、S9、S10。

[編輯]

我已經設法將折線圖疊加在堆積長條圖上。但我需要一個非連續的線圖。

目前，點 (S3,S4)、(S6,S7) 也已連接，這是我不希望出現在圖表中的。我怎麼才能產生這樣的圖表？

我最初認為這可以透過單一\addplot命令來完成，而無需修改資料表；顯然情況並非如此（參見如何打斷劇情？）。

但是，您可以將圖分成三個並使用限制域restrict x to domain，如建議的阿爾夫C在他的回答對於連結的問題：
