在 tikz/pgf latex 中创建一个 punktchain 或流程图，该图有两列，然后合并为一列，再合并为两列

Question

我已经更新了示例代码，添加了一些注释，以便真正接近我想要的效果。现在我只想要两条线从过滤器 1 和过滤器 2 内联出来，并且具有与较小块中已有的相同的线样式。我认为这应该相对容易，但我只能弄清楚如何将线从块的中心移出。

                         ;

这是最终的解决方案，但我得到了一个杂乱的箭头，我不知道如何去掉它。我所做的只是将上面的代码更改为下面的两条路径线，没有其他更改。

代码在这里：

\path[myline,->,shorter]  {[|*] (A1) edge (B)}
                              ([shift={(-2.25cm,0)}]B.south)  edge ([shift={(-2.25cm,0)}]C.north)
                              ([shift={(-2.25cm,0)}]C.south)  edge ([shift={(-2.25cm,0)}]D.north)
                          {[*|] (D)  edge (E1)}
                         ;
\path[mylinedot,->,shorter]  {[|*] (A2) edge (B) }
                              ([shift={(2.25cm,0)}]B.south)  edge ([shift={(2.25cm,0)}]C.north)
                              ([shift={(2.25cm,0)}]C.south)  edge ([shift={(2.25cm,0)}]D.north)
                          {[*|] (D) edge (E2)}
                          (E1) edge (E2)
                         ;

Answer 1

这就是你想要的吗？基本上，输入/输出角度选项edge [in=..., out=...]被删除，并且块之间的连接线/路径不居中，而是移到一边，以便可以清楚地看到火车路径和测试路径。

Answer 2

_{评论太长了。}

你正在定义

myline/.style={draw, very thick,black, <-, node distance=1.1cm},
mylinedot/.style={draw, very thick, blue!100!black!70, densely dotted, <-, node distance=1cm},

即让箭头朝后。而在你的\path命令中，你使用的是->朝前的箭头。从和->的定义中 删除，并将其用作每个边的选项，例如。即myline/.stylemylinedot/.style->edge[->]

\path[myline,,shorter]  {[|*] (A1) edge[->] (B)}
                              ([shift={(-2.25cm,0)}]B.south)  edge[->] ([shift={(-2.25cm,0)}]C.north)
                              ([shift={(-2.25cm,0)}]C.south)  edge[->] ([shift={(-2.25cm,0)}]D.north)
                          {[*|] (D)  edge[->] (E1)}
                         ;
\path[mylinedot,shorter]  {[|*] (A2) edge[->] (B) }
                             ([shift={(2.25cm,0)}]B.south)  edge[->] ([shift={(2.25cm,0)}]C.north)
                              ([shift={(2.25cm,0)}]C.south)  edge[->] ([shift={(2.25cm,0)}]D.north)
                          {[*|] (D) edge[->] (E2)}
                          (E1) edge[->] (E2)
                         ;
