我是 tex 新手，正在创建流程图。我能够基于找到的一些模板进行构建，但无法修改 3 个功能：
- 我希望边缘（线）是“分叉的”，而不是成角度的线。
- 我想在最后一列的末尾放置（花括号），但我创建的边缘从最后一列的中心而不是右侧突出。应该有两个这样的括号，第一个括号括前 8 个框，第二个括号括后 8 个框。我还想在括号上放置标签，写着“v1”或“v2”。
- 最后，我想摆脱线顶部的 v/X/Y/Z 之间的边缘。
以下是我想要的结果：
目前的代码如下：

后续问题： 森林功能看起来很棒！我遇到一个问题，当我在框中输入较长的文本时，框的长度不一致，这会打乱树木的排列。
我如何指定矩形的大小，以便它们在不同的“兄弟级别”中保持一致？

答案1
我认为使用 会更容易forest。括号是最棘手的部分，需要decorations.pathreplacing和 库。我为此calligraphy制作了一个样式。然后可以使用它们以及节点的 s 来绘制它们。mybrace\draw[mybrace]name
