在 Beamer 中垂直居中 tikz 图

我想知道如何制作幻灯片中垂直居中的图表。该图表是使用 tikz 绘制的。代码如下。非常感谢！

以下是 2021/9/2 Holger Karl 的代码输出： 在此处输入图片描述

答案1

@Ignasi 的回答Latex beamer：如何水平/垂直居中文本，忽略其他内容

就我的情况来说，

\begin{frame}{}
\begin{tikzpicture}[overlay, remember picture]
\node[anchor=center] at (current page.center) {
\begin{tikzpicture}[xscale=0.6,yscale=0.6]
blabla
\end{tikzpicture}
};
\end{tikzpicture}
\end{frame}

答案2

图形环境之前和之后能\vfill起作用吗？就像这样，代码被精简了：

\documentclass{beamer}

\usepackage{tikz}

\mode<presentation>
{
  \usetheme{AnnArbor}      % or try Darmstadt, Madrid, Warsaw, ...
  \usecolortheme{wolverine} % or try albatross, beaver, crane, ...
  \usefonttheme{default}  % or try serif, structurebold, ...
  \setbeamertemplate{navigation symbols}{}
  \setbeamertemplate{caption}[numbered]
} 



\begin{document}

\begin{frame}

% possibly add vfill here: 
%\vfill
\begin{tikzpicture}[xscale=0.4,yscale=0.4]

\draw [fill] (-11.5,6) circle [radius=0.7];
\draw [fill=gray] (-10,6) circle [radius=0.45];
\draw [fill=gray] (-8.8,6) circle [radius=0.45];
\draw [fill=gray] (-7.6,6) circle [radius=0.45];
\draw [fill=gray] (-6.4,6) circle [radius=0.45];
\draw [fill] (-3.5,6) circle [radius=0.7];
\draw [fill=gray] (0,2.4) circle [radius=0.45];
\draw [fill=gray] (2,2.4) circle [radius=0.45];
\draw [fill=gray] (4,2.4) circle [radius=0.45];  
\draw [fill=gray] (6,2.4) circle [radius=0.45];

\draw (0,7.8) -- (-3,6.2);
\draw (0,7.8) -- (3,6.2);
\draw (3,6.2) -- (1,4);
\draw (3,6.2) -- (5,4);
\draw (1,4) -- (0,2.8);
\draw (1,4) -- (2,2.8);
\draw (5,4) -- (4,2.8);
\draw (5,4) -- (6,2.8);

\end{tikzpicture}    

% possibly add vfill here: 
%\vfill

\end{frame}


\end{document}
