Beamer - 方框文本图表

Beamer - 方框文本图表

我正在编写 Beamer 演示文稿，但无法找到一种方法来将各种框内文本关联到一页内的图表中。我尝试使用列环境，但我的解决方案在我看来太幼稚了：

1）箭头对于我的目的来说太短了；

2）对齐取决于文本的长度，并且只能通过仔细调整空格跳跃才能获得；

3）我看不出最终能添加诸如对角箭头之类的更复杂功能的方法；

tikz 方法可能会更有效率。

\documentclass[aspectratio=169]{beamer}
\usepackage{lmodern}
\usepackage{tikz}
\usetheme{Boadilla}
\usepackage[overlay]{textpos}

\begin{frame}{Title here}
\begin{columns}[t]
\column{0.25\textwidth}
\centering

\begin{block}{}
Some text with math formulae e.g. $\alpha=f$
\end{block}
\vspace{1.7cm}

\begin{block}{}
Some text with math formulae e.g. $\alpha=f$
\end{block}
\column{0.30\textwidth}
\center
$\overset{\mathrm{long text here}}{\longrightarrow}$

\vspace{1.7cm}

$\overset{\mathrm{long text here}}{\longleftrightarrow}$

\column{0.25\textwidth}
\begin{block}{}
Some text with math formulae e.g. $\alpha=f$
\end{block}

\vspace{1.7cm}

\begin{block}{}
Some text with math formulae e.g. $\alpha=f$
\end{block}
\end{columns}
\end{frame}

你是对的，用tikz更简单的方法来绘制你的关系：

在此处输入图片描述

\documentclass[aspectratio=169]{beamer}
\usepackage{lmodern}
\usepackage{tikz}
\usetheme{Boadilla}
\usepackage[overlay]{textpos}

\usepackage{tikz}
\usetikzlibrary{arrows.meta, positioning, shadows}

\begin{document}
\begin{frame}
\frametitle{Title here}
    \begin{center}
    \begin{tikzpicture}[
    node distance = 11mm and 44mm,
block/.style = {rectangle, rounded corners, fill=gray!30,
                text width=0.24\linewidth, align=left,
                drop shadow},
   LA/.style = {-Straight Barb, semithick,              % LA: left arrow
                shorten >=3mm, shorten <=3mm},
  LRA/.style = {Straight Barb-Straight Barb, semithick, % LRA: left right arrow
                shorten >=3mm, shorten <=3mm}
                      ]
\node (n1) [block]              {Some text with math formulae e.g. $\alpha=f$};
\node (n2) [block,right=of n1]  {Some text with math formulae e.g. $\alpha=f$};
\node (n3) [block,below=of n1]  {Some text with math formulae e.g. $\alpha=f$};
\node (n4) [block,right=of n3]  {Some text with math formulae e.g. $\alpha=f$};
%
\draw[LA]   (n1) -- node[above] {long text here} (n2);
\draw[LRA]  (n3) -- node[above] {long text here} (n4);
    \end{tikzpicture}
    \end{center}
\end{frame}
\end{document}

只是为了完整性，以防你不想用 Ti 重新发明投影机块钾Z，每次更改外观时都要重新调整。您可以将箭头添加为覆盖层。

\documentclass[aspectratio=169]{beamer}
\usepackage{lmodern}
\usepackage{tikz}
\usetikzlibrary{calc}
\tikzset{Connect/.style={ultra thick,>=latex,shorten >=0.5cm,shorten <=1cm}}
\newcommand{\tikznode}[2]{\tikz[remember picture,baseline=(#1.base),inner
     sep=0pt]{\node(#1)[inner sep=0pt]{#2};}}
\usetheme{Boadilla}
\usepackage[overlay]{textpos}

\begin{document}
\begin{frame}{Title here}
\begin{overlayarea}{\textwidth}{8cm}
\begin{columns}[t]
\column{0.25\textwidth}
\centering

\begin{block}{}
\tikznode{1a}{\strut}Some text with math formulae e.g.\ $\alpha=f$\tikznode{1b}{\strut}
\end{block}
\vspace{1.7cm}

\begin{block}{}
\tikznode{2a}{\strut}
Some text with math formulae e.g.\ $\alpha=f$
\tikznode{2b}{\strut}
\end{block}
\column{0.30\textwidth}
\center

\vspace{1.7cm}


\column{0.25\textwidth}
\begin{block}{}
\tikznode{3a}{\strut}Some text with math formulae e.g.\ $\alpha=f$\tikznode{3b}{\strut}
\end{block}

\vspace{1.7cm}

\begin{block}{}
\tikznode{4a}{\strut}Some text with math formulae e.g.\ $\alpha=f$\tikznode{4b}{\strut}
\end{block}
\end{columns}%
\begin{tikzpicture}[overlay,remember picture]
\draw[Connect,->] ($(1a-|1b)!0.5!(1b)$) -- ($(3a)!0.5!(3a|-3b)$)
node[pos=0.55,above]{some text here};
\draw[Connect,<->] ($(2a-|2b)!0.5!(2b)$) -- ($(4a)!0.5!(4a|-4b)$)
node[pos=0.55,above]{some other text here};
\end{tikzpicture}
\end{overlayarea}
\end{frame}
\end{document}

我还添加了一个覆盖区域，以防您想暂停。这可以防止幻灯片跳动。

为什么采用 tikz 方法？

姆韦

\documentclass[aspectratio=169]{beamer}
\usepackage{lmodern}
\usepackage{amsmath}
\usetheme{Boadilla}
\begin{document}
\begin{frame}{Title here}
\centering
\begin{minipage}{4cm}
\begin{block}{}
    Some text with math formulae e.g. $\alpha=f$
\end{block}
\end{minipage} 
$\underrightarrow{\makebox[3cm][r]{long text here}\hspace{3em}}$
\begin{minipage}{4cm}
\begin{block}{}
    Some text with math formulae e.g. $\alpha=f$
\end{block}
\end{minipage}
\vfill
\begin{minipage}{4cm}
\begin{block}{}
    Some text with math formulae e.g. $\alpha=f$
\end{block}
\end{minipage} 
$\underleftrightarrow{\makebox[3cm][r]{long text here}\hspace{3em}}$
\begin{minipage}{4cm}
\begin{block}{}
    Some text with math formulae e.g. $\alpha=f$
\end{block}
\end{minipage}
\end{frame}
\end{document}
