最近我发现我可以创造蒂克兹演示文稿投影仪文件中的图形。以前我习惯单独创建 pdf 文件并将其导入到演示文稿中。通过应用新流程，我遇到了一个问题，我不知道如何解决它。
我想在一张幻灯片中使用两个单独的 tikz 图形，它们将使用 \visible<1-2>{} 效果一个接一个地出现。我以前通过导入图形或 pdf 文件成功做到了这一点，但现在我陷入了困境。
我不知道如何使所有图形的垂直和水平间距相同。
代码示例演示了我的问题。幻灯片 2 和幻灯片 3 之间的问题很容易发现。图形移动到了不同的位置。
我使用了 \vspace{} 并设法使它们更接近一些，但不是我想要的结果。
有人知道如何提高我的产出吗？
提前感谢您花时间和精力阅读和回答我的问题。

更新
在这个更新版本中，我仍然使用\only而不是\visible，并使用visible on样式来大大简化代码；使用这种新方法，图像不会“跳跃”，因为大部分图形保持不变（overlayarea仍然可以使用，但我认为不再需要了）。计数器subfigure必须手动更新：

\tikzset{
invisible/.style={opacity=0,text opacity=0},
visible on/.style={alt=#1{}{invisible}},
alt/.code args={<#1>#2#3}{%
\alt<#1>{\pgfkeysalso{#2}}{\pgfkeysalso{#3}}
}
}
\mode<presentation>
\usetheme{Dresden} % so so
\setbeamertemplate{blocks}[rounded][shadow=true]
\setbeamertemplate{navigation symbols}{} %take out the navigation symbols

评论
您无需使用两个单独的
tikzpicture环境，只需使用一个环境，而且 TikZ 的构造具有叠加感知功能。这将大大缩短代码，并解决图像跳跃的问题。请注意，不建议将该
subcaption包与 一起使用beamer；您应该使用subfig相反；无论如何，如果您决定使用subcaption，则需要使用caption模式compatibility=false，因此请像这样加载包：\usepackage[compatibility=false]{caption} \usepackage{subcaption}
