在 tikz 节点下方/上方添加大括号

我怎样才能延长大支架，使其不仅覆盖yyyy而且还能覆盖uuuu节点？

\tikzstyle{level 1}=[level distance=3.5cm, sibling distance=3.5cm]
\tikzstyle{level 2}=[level distance=3.5cm, sibling distance=2cm]
\begin{figure}
\centering
\begin{tikzpicture}[grow=right, sloped]
\node[draw] {ppp\textsuperscript{p}}        
            child {
                node[draw, circle, label=right:
                    {$xxxx$}]
{}
                edge from parent
                node[above] {xx}
                node[below]  {$xxxx$}
            }
            child {
                node[draw, circle, label=right:
                    {$uuuu$}] 
{}
                edge from parent
                node[above] {uu}
                node[below]  {$uuuu$}
             }
            child {
                node[draw, circle,label=right:
                    {$yyyy \Bigg\} $}] 
{}
                edge from parent
                node[above] {yy}
                node[below]  {$yyyy$}
    };
\end{tikzpicture}
\end{figure}

我\smash编辑了又\raisebox编辑一个零宽度\rule，它后面跟着一个右括号。

\documentclass{article}
\usepackage{tikz}
\begin{document}
\tikzstyle{level 1}=[level distance=3.5cm, sibling distance=3.5cm]
\tikzstyle{level 2}=[level distance=3.5cm, sibling distance=2cm]
\begin{figure}
\centering
\begin{tikzpicture}[grow=right, sloped]
\node[draw] {ppp\textsuperscript{p}}        
            child {
                node[draw, circle, label=right:
                    {$xxxx$}]
{}
                edge from parent
                node[above] {xx}
                node[below]  {$xxxx$}
            }
            child {
                node[draw, circle, label=right:
                    {$uuuu$}] 
{}
                edge from parent
                node[above] {uu}
                node[below]  {$uuuu$}
             }
            child {
                node[draw, circle,label=right:
                    {$yyyy 
            \smash{\raisebox{-52pt}{$\left.\rule{0pt}{60pt}\right\}$}} $}] 
{}
                edge from parent
                node[above] {yy}
                node[below]  {$yyyy$}
    };
\end{tikzpicture}
\end{figure}
\end{document}

在此处输入图片描述

您可以为相关节点添加标签

            child {
                node[draw, circle, label=right:
                    {$uuuu$}] (U)
{}

类似地(Y)，然后你可以画一个括号作为装饰：

\draw [decoration={brace,amplitude=8pt},decorate] ($(Y)+(3.5em,1ex)$) -- ($(U)+(3.5em,-1ex)$);

由于标签和需要获得额外的高度，因此需要此处的偏移量。我已根据ex和指定了这些em，因为这些是取决于字体大小的单位。

            child {
                node[draw, circle, label=right:
                    {$xxxx$}]
{}
                edge from parent
                node[above] {xx}
                node[below]  {$xxxx$}
            }
            child {
                node[draw, circle, label=right:
                    {$uuuu$}] (U)
{}
                edge from parent
                node[above] {uu}
                node[below]  {$uuuu$}
             }
            child {
                node[draw, circle,label=right:
                    {$yyyy$}] (Y)
