分成两列的 beamer 框架必须在一列包含一个 tikz 图片（饼图），在第二列包含另外两张 tikz 图片。
第一张图片一切正常，但添加另外两张图片会导致编译器停止（紧急停止）。
我尝试复制所显示完全相同的 tikzpicture 代码，但它仍然不起作用。
以下是功能代码，其中在另外两个饼图的位置处添加了注释。
\documentclass{beamer}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage{tikz}
\begin{document}
\begin{frame}
\def\angle{0}
\def\radius{3}
\def\cyclelist{{"blue","red","green"}}
\newcount\cyclecount \cyclecount=-1
\newcount\ind \ind=-1

\global\advance\ind by 1 % Advance list index

\pgfmathparse{\cyclelist[\the\ind]} % Get color from cycle list
\edef\color{\pgfmathresult} % and store as \color
% Draw angle and set labels

\node at (\angle+0.5*\percent*3.6:0.7*\radius) {\percent\,\%};
\node[pin=\angle+0.5*\percent*3.6:\name]

您需要重新启动计数器\cyclecount，并对\ind每张图片使用它们：

\cyclecount=-1
\newcount\ind
\ind=-1
