![tikz 将文本放在矩形下方](https://linux22.com/image/340046/tikz%20%E5%B0%86%E6%96%87%E6%9C%AC%E6%94%BE%E5%9C%A8%E7%9F%A9%E5%BD%A2%E4%B8%8B%E6%96%B9.png)
有两个问题:(1) 红色和蓝色矩形的高度不同,(2) 标签stack
未buffer
居中对齐。我是 tikz 新手,有人可以指点一些可以改进图形的方向吗?
\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows}
\usetikzlibrary{calc}
\begin{document}
\begin{tikzpicture}[->,>=stealth',node distance=1cm]
\draw [help lines] (0,0) grid (6,2);
\node [text] (1) {I};
\node [text] (2) [right of=1] {booked};
\node [text] (3) [right of=2] {a};
\node [text] (4) [right of=3] {ticket};
\node [text] (5) [right of=4] {to};
\node [text] (6) [right of=5] {China};
\path (2) edge[bend right=70] node [above]{nsubj} (1);
\path (2) edge[bend left=90] node [above]{dobj} (4);
\path (4) edge[bend right=70] node [left]{det} (3);
\path (4) edge[bend left=70] node [above]{prep} (5);
\path (5) edge[bend left=70] node [above]{pobj} (6);
\draw [red,thick,minimum height=2cm] (stack) ($(1.north west)$) rectangle ($(2.south east)$);
\node [text,align=center] [below=stack] {stack};
\draw [blue,thick,minimum height=2cm] (buffer) ($(3.north west)$) rectangle ($(6.south east)$);
\node [text,align=center] [below=buffer] {buffer};
\end{tikzpicture}
\end{document}

你喜欢获得这样的东西吗?
我显著改变了你的 MWE:
- 引入新库:
chains
,fit
和quotes
, - 删除
calc
,因为它没有被使用 - 对于红色和蓝色矩形使用节点,适合
txt
节点 - 定义新样式:(
txt
在text
TikZ 中使用名称,不能用于本地定义的样式)并重新定义edge
样式 - 对于边缘标签使用库
quotes
- 红色和蓝色矩形下方的文本是相应节点的标签
完成 MWE:
\documentclass[tikz,
border=3mm]{standalone}
\usetikzlibrary{arrows, chains, fit, quotes}
\begin{document}
\begin{tikzpicture}[
node distance = 10mm,
start chain = A going right,
txt/.style = {text height=2ex, text depth=0.25ex,
on chain},
every edge/.append style = {draw, -stealth'}
]
\draw [help lines] (-1,-1) grid (10,2);
\node [txt] {I}; % nodes are in the chain
\node [txt] {booked};
\node [txt] {a};
\node [txt] {ticket};
\node [txt] {to};
\node [txt] {China};
%
\node (f1) [draw=red, inner sep=0pt, % red rectangle
label=below:stack, % "node below rectangle done by node label
fit=(A-1) (A-2)] {};
\node (f2) [draw=blue,inner sep=0pt, % blue rectangle
label=below:buffer,% "node below rectangle done by node label
fit=(A-3) (A-6)] {};
%
\path (A-2) edge[bend right=70, "nsubj" '] (A-1)
(A-2) edge[bend left=90, "dobj" ] (A-4)
(A-4) edge[bend right=70, "det" '] (A-3)
(A-4) edge[bend left=70, "prep" ] (A-5)
(A-5) edge[bend left=70, "pobj" ] (A-6);
\end{tikzpicture}
\end{document}
