我想知道如何在 TikZ 中用花括号连接节点。下图显示了我想要做的事情：
这是我已经得到的：
\documentclass[class=minimal,border=0pt]{standalone}
\usepackage{pgfplots}
\usepackage{tikz}
\usetikzlibrary{shapes.geometric, arrows.meta}
\begin{document}
\begin{tikzpicture}
\tikzstyle{myrect} = [rectangle,draw,thin,minimum width=3cm,minimum height=1cm,align=center]
\node (MD) [myrect] {Texttexttext};
\node (Z1) [myrect,above of=MD,yshift=0.5cm,minimum width=1.2cm] {Z1};
\node (Z2) [myrect,left of=Z1,xshift=-1.5cm,minimum width=1.2cm,opacity=.2,text opacity=.2] {Z2};
\node (Z3) [rectangle,left of=Z1,xshift=-0.5cm,minimum width=1.2cm] {$\cdots$};
\node (X1) [myrect,above of=Z1,xshift=1.5cm,yshift=0.5cm,minimum width=1cm] {X1};
\node (X2) [myrect,left of=X1,minimum width=1cm] {X2};
\node (X3) [myrect,left of=X2,minimum width=1cm] {X3};
\node (X4) [myrect,left of=X3,minimum width=1cm] {X4};
\node (X5) [myrect,left of=X4,minimum width=1cm] {X5};
\draw [decorate,decoration={brace,amplitude=0.5cm,mirror}] (Z1.south west) -- (Z1.south east);
\draw [decorate,decoration={brace,amplitude=0.5cm,mirror}] (X5.south west) -- (X1.south east);
\end{tikzpicture}
\end{document}
括号看起来还是有点糟糕，那么有没有一种自动且好用的方法用括号连接节点？还是我必须通过坐标精确定位它们？
问候！
答案1
“通过括号连接节点”是不可能的，但您可以稍微调整一下raise选项amplitude以获得更好的结果。
下面的代码显示了您的一些更改：
tikzstyle取而代之tikzset：应该使用 \tikzset 还是 \tikzstyle 来定义 TikZ 样式？旧语法已被库中的
left|right|above|... of=新语法取代left|right|... = ofpositioning最顶层的数组已由 构建
X3。这种方式更容易垂直对齐所有节点。
完整的代码如下：
\documentclass[class=minimal,border=2mm]{standalone}
%\usepackage{pgfplots}
\usepackage{tikz}
\usetikzlibrary{shapes.geometric, arrows.meta, positioning, decorations.pathreplacing}
\begin{document}
\begin{tikzpicture}[myrect/.style={rectangle, draw, thin, minimum height=1cm, align=center}]
\node (MD) [myrect, minimum width=3cm] {Texttexttext};
\node (Z1) [myrect, above=4mm of MD, minimum width=1.2cm] {Z1};
\node (Z2) [myrect, left = of Z1, minimum width=1.2cm, opacity=.2, text opacity=.2] {Z2};
\path (Z2) -- (Z1) node[midway]{\dots};
\node (X3) [myrect,above= 4mm of Z1] {X3};
\node (X4) [myrect,left = -\pgflinewidth of X3] {X4};
\node (X5) [myrect,left = -\pgflinewidth of X4] {X5};
\node (X2) [myrect,right = -\pgflinewidth of X3] {X2};
\node (X1) [myrect,right = -\pgflinewidth of X2] {X1};
\draw [decorate,decoration={brace,amplitude=3mm,mirror, raise=.5mm}] (Z1.south west) -- (Z1.south east);
\draw [decorate,decoration={brace,amplitude=3mm,mirror,raise=.5mm}] (X5.south west) -- (X1.south east);
\end{tikzpicture}
\end{document}
结果
