I would like to replace the single arrows in the code below to 2 arrows (to and from each node). I need to animate it, so I want to adjust to adjust the code in first slide to produce that.

\documentclass{beamer}
\mode<presentation>{\usetheme{Madrid}}

\usepackage{tikz}
\usetikzlibrary{backgrounds,fit,matrix}


\tikzstyle{bigbox} = [minimum size=3cm,draw=blue!50, thick, fill=blue!10, rounded corners, rectangle]
\tikzstyle{box} = [minimum size=1.5cm, rounded corners,rectangle, fill=blue!50]
\tikzstyle{arrow} = [thick,->,>=stealth]


\begin{document}


\begin{frame}[fragile]


\begin{tikzpicture}


\node (box11) [box] {11};


\node (box12) [box, right of=box11,xshift=2cm] {12};


\node (box13) [box, right of=box12,xshift=2cm] {13};


\node (box21) [box, below of=box11,yshift=4cm] {21};


\node (box22) [box, right of=box21,xshift=2cm] {22};


\node (box23) [box, right of=box22,xshift=2cm] {23};


\draw<.(1)-> [arrow] (box11) -- (box12);
\draw<.(1)-> [arrow] (box12) -- (box13);
\draw<.(1)-> [arrow] (box21) -- (box22);
\draw<.(1)-> [arrow] (box22) -- (box23);
\draw<.(1)-> [arrow] (box12) -- (box22);
\draw<.(1)-> [arrow] (box13) -- (box23);


\end{tikzpicture}
\end{frame}


\end{document}

  • Please provide a sketch of desired result. Your description of your wish is not very clear. Can be arrows bended? – Zarko Aug 07 '20 at 14:37

  • Yes, exactly. But in the matrix environment, is there a possibility to animate it, i.e., to control when each box (11 till 23) appear in transition slides. For example, each box appears on each slide. – Curious Aug 07 '20 at 16:07
  • @Curious, this is new question. Ask it as such! Anyway, see http://tex.stackexchange.com/questions/294908/ – Zarko Aug 07 '20 at 17:44

Use

\tikzstyle{arrow} = [thick,<->,>=stealth]
