演示投影机暂停图

在此处输入图片描述

我想在 beamer 中显示图表，这样每次点击条目时我们都能看到下一步，但当然是在单个图表中

\begin{figure}[!h]

\draw [->] (-4.5,-1)--(.5,-1);
\foreach \i in {-4,...,0} {
  \draw (\i,-.9)--(\i,-1.1) node[below] {\i};
}
\foreach \i/\j in {-4/4,-4/3,-4/2,-4/1,-3/2,-2/3,-3/1,-2/2,-1/3,-1/4,0/3,0/4} {\node[draw,circle,fill=cyan!9](\i_\j) at (\i,4-\j) {$\j$};
}
\foreach \i/\j in {-3/4,-2/1,-1/2,-3/3,-2/4,-1/1,0/2,0/1} {\node[draw,circle,dash pattern=on 1.5pt off 1.5pt](\i_\j) at (\i,4-\j) {$\j$};

因此，第一状态的每个箭头都会生成适合第二状态的周长，因此接下来的时间会回到过去，并且在没有得到箭头的状态之后重新制作相同的状态，或者用胸部画出来

答案1

使用更简单的 MWE。这说明了我的评论。请注意，您必须运行 LaTeX 两次才能使前三张幻灯片对齐。这种opacity=0方法更适合居中（图形环境），但您必须小心不要添加额外的空格。

\documentclass{beamer}
\usepackage{tikz}
\begin{document}

\begin{frame}
\begin{figure}
\begin{tikzpicture}[remember picture]
  \node[draw,circle] (A) {First};
  \path (4,0);% set right boundary for centering
\end{tikzpicture}
\onslide<2-> {\begin{tikzpicture}[remember picture, overlay]
  \node[draw,circle,right=1.5cm] (B) at (A) {Second};
  \draw[->] (A) -- (B);
  \end{tikzpicture}}
\onslide<3-> {\begin{tikzpicture}[remember picture, overlay]
  \node[draw,circle,right=1.5cm] (C) at (B) {Third};
  \draw[->] (B) -- (C);
  \end{tikzpicture}}
\end{figure}
\end{frame}


\begin{frame}
\begin{figure}
\only<1> {\begin{tikzpicture}
  \node[draw,circle] (A) {First};
  \begin{scope}[opacity=0]
    \node[draw,circle,right=1.5cm] (B) at (A) {Second};
    \draw[->] (A) -- (B);
    \node[draw,circle,right=1.5cm] (C) at (B) {Third};
