![TikZ:重新排列层次图](https://linux22.com/image/294397/TikZ%EF%BC%9A%E9%87%8D%E6%96%B0%E6%8E%92%E5%88%97%E5%B1%82%E6%AC%A1%E5%9B%BE.png)
我对“cfr”针对该问题给出的解决方案印象深刻这里。
您能否建议一种方法来将两个主要子节点(标记为投影矩阵理论和重建算法)更改为位于根节点(压缩感知理论)的北部和南部?也就是说,我希望两个主要子节点向根节点的北部和南部展开。主要子节点“重建算法”应出现在根节点正下方,子节点“投影矩阵理论”应出现在根节点上方。“投影矩阵理论”的子节点应向上展开,而“重建算法”的子节点可以保持完整。
我曾对 cfr 的回答发表评论,请求同样的回复。正如他所建议的,我将其作为新问题再次发布。谢谢。
编辑:我试图改变它,但最终却得到了这个数字!
我修改的代码如下:

我无法将节点“投影矩阵理论”放置在根节点“压缩感知”上方。同样,节点“投影矩阵理论”的箭头没有在预期位置结束。我哪里做错了?
答案1
正如我在评论中所说,forest
它实际上并不是为这种图表设计的(在我看来)。在给定子树的给定级别,生长方向就是生长方向。您不能为一个子级指定一个方向,而为另一个子级指定另一个方向。
因此,要画出我认为你想要的东西,你需要假装它。这里的技巧是从一个东方- 生长树和带有三个子节点的根节点。我们不关心根节点。它只允许三个节点垂直对齐。伪根节点位于中心,两个子树根节点位于上方和下方。

当然,该图不再是分层的。相反,它包括几个相互竞争的层次结构……
