我希望在几个节点下面有一个花括号,如图所示。我试着遵循这个例子,但我无法理解。
谢谢
\documentclass[11pt]{report}
\usepackage{tikz}
\usetikzlibrary{positioning}
\usetikzlibrary{bayesnet}
\begin{document}
\begin{figure}
\centering
\tikz{ %
\node[latent] (phi) {$\phi$};
\node[latent, above = of phi] (y) {$y$};
\node[obs, left = of y] (Obs_y) {$ \tilde {\bf{y}}$};
\node[latent, below = of Obs_y] (sigma) {$\sigma_y$};
\edge {phi} {y};
\edge {y, sigma} {Obs_y};
}
\end{figure}
\end{document}

这是实现此目的的一种方法。
\documentclass[11pt]{report}
\usepackage{tikz}
\usetikzlibrary{positioning,decorations.pathreplacing,calc}
\usetikzlibrary{bayesnet}
\begin{document}
\begin{figure}
\centering
\tikz{ %
\node[latent] (phi) {$\phi$};
\node[latent, above = of phi] (y) {$y$};
\node[obs, left = of y] (Obs_y) {$ \tilde {\bf{y}}$};
\node[latent, below = of Obs_y] (sigma) {$\sigma_y$};
\edge {phi} {y};
\edge {y, sigma} {Obs_y};
\draw[decorate,decoration={brace}] ($(sigma)+(0.5,-0.5)$) --
node[below]{$x$} ++(-1,0) ;
}
\end{figure}
\end{document}
对于下面的底部的支撑sigma_y
,phi
你可以使用
\documentclass[11pt]{report}
\usepackage{tikz}
\usetikzlibrary{positioning,decorations.pathreplacing,quotes}
\usetikzlibrary{bayesnet}
\begin{document}
\begin{figure}
\centering
\tikz{ %
\node[latent] (phi) {$\phi$};
\node[latent, above = of phi] (y) {$y$};
\node[obs, left = of y] (Obs_y) {$ \tilde {\bf{y}}$};
\node[latent, below = of Obs_y] (sigma) {$\sigma_y$};
\edge {phi} {y};
\edge {y, sigma} {Obs_y};
\path (sigma.south west)
edge[decorate,decoration={brace,mirror,raise=.15cm},"$x$"below=6pt]
(sigma.south west -| phi.south east);
}
\end{figure}
\end{document}
