使用 pgfplots 叠加在“分组堆积”条形图上的折线图？

我需要在堆叠的分组条形图上叠加一条线图（类似于回答以下问题：条形图中的两级标签）。

我必须为每个组叠加一个线图（它在组边界处断开）。例如：第一个线图连接 S1、S2、S3；第二个线图连接 S4、S5、S6；最后一个线图连接 S7、S8、S9、S10。

[编辑]

我已经设法将线图叠加在堆积条形图上。但我需要一个非连续的线图。

目前，点 (S3,S4)、(S6,S7) 也已连接，但我不想将其显示在图中。如何生成这样的图？

我最初以为这可以通过一个\addplot命令完成，而无需修改数据表；显然事实并非如此（参见如何打断剧情？）。

但是，你可以将图分成三部分，并使用 限制域restrict x to domain，如建议的那样阿尔法在他的回答对于链接的问题：
