问题是我想改变两个子图中间边标签的位置,同时让标题不出现在图中。谢谢您的帮助
答案1
@marmot建议使用pos
key,这很好,但它无法让您完全按照自己的意愿进行操作。它只占用了 90% 的路程。以下是仅使用 key 时的效果pos=0.8
(即从起始节点到终止节点的 80%):
您会注意到标签的位置并不准确。有两种方法(或两种方法)可以解决这个问题。最简单的方法是还除了 之外,还指定位置(例如above
、east
、等) 。这是完整的 MWE,以及为这些线标签指定的锚点和:below
pos=...
pos

在我看来,这满足了你的需要...但是如果你想更多的灵活性,也可以考虑使用xshift
或yshift
作为节点标签。在这里,我将xshift
左下角问A1A2使用标签xshift=25
(仅使用 25 来清晰显示变化)。回想一下,正数xshift
向右移动,负数向左移动;正数yshift
向上移动,负数向下移动。
在这个例子中,我只更改:
%edge [above left,pos=0.8] node {$\QAot$} (J)% without xshift (current version)
%%%%to
edge [above left,pos=0.8] node[xshift=25] {$\QAot$} (J)
希望这些选项能给您带来所需的灵活性!
