我正在尝试连接一些节点,tikz
但有些东西无法正常工作。关于第三条路径:
1-) 我怎样才能让它向左移动或从“第三个量”的顶部向等式中指定项的中心底部移动?目前它正在向上移动并到达左侧。
2-) 是否可以将“第二数量”和“第三数量”放在同一行?

答案1
如果我理解正确的话,对于 1),使用out=90,in=270
而不是bend left
来edge
画线。对于 2),删除环境flushright
,并在属于和 的\hfill
节点之间添加一个。Second..
Third ..
(我可能误解了你对第一个问题的意思,如果你想要不同的东西,请发表评论。)

如果您希望箭头从单词中间开始,则有几个选项。一个是将 移动到\tikz\node...
单词之间,因为这是定义起点的地方。在这种情况下,您可能希望将其向上移动一点,因此不要使用样式na
,而是添加类似 的内容baseline=-1.5ex
。
第二种选择是将单词本身放在节点中,因此不要说Second quantity\tikz\node...
,而是使用。然后,您可以从(或)\tikz[na]\node(n2){Second quantity};
开始箭头。以下代码演示了这两个选项。n2.south
north
