我无法将饼图添加到 cvitem

Question

好的。我猜 MNWE 看起来像这样：

\documentclass[14pt,a4paper,san]{moderncv}
\moderncvstyle{classic}
\moderncvcolor{blue}
\name{a}{a}
\title{s}
\address{}{s}
\email{}
\phone[mobile]{1212}
\begin{document}

\cvitem{}{%
  \def\angle{0}
  \def\radius{3}
  \def\cyclelist{{"orange","blue","red","green"}}
  \newcount\cyclecount \cyclecount=-1
  \newcount\ind \ind=-1
  \begin{tikzpicture}[nodes = {font=\sffamily}]
    \foreach \percent/\name in {
      8/C++,8/Linux,7/Arduino,6/Python,6/Erlang,5/H5
    } {
      \ifx\percent\empty\else               % If \percent is empty, do nothing
      \global\advance\cyclecount by 1     % Advance cyclecount
      \global\advance\ind by 1            % Advance list index
      \ifnum3<\cyclecount                 % If cyclecount is larger than list
      \global\cyclecount=0              %   reset cyclecount and
      \global\ind=0                     %   reset list index
      \fi
      \pgfmathparse{\cyclelist[\the\ind]} % Get color from cycle list
      \edef\color{\pgfmathresult}         %   and store as \color
      % Draw angle and set labels
      \draw[fill={\color!50},draw={\color}] (0,0) -- (\angle:\radius) arc (\angle:\angle+\percent*1.8*2.5:\radius) -- cycle;

      \node at (\angle+0.5*\percent*1.8*2.5:0.7*\radius) {\name};
      \pgfmathparse{\angle+\percent*1.8*2.5}  % Advance angle
      \xdef\angle{\pgfmathresult}         %   and store in \angle
      \fi
    };
  \end{tikzpicture}%
}

\clearpage
\end{document}

这里的问题是，你在参数中有一个段落中断，即\cvitem一个空白行。因此，最小的修复方法是

\documentclass[14pt,a4paper,san]{moderncv}
\moderncvstyle{classic}
\moderncvcolor{blue}
\name{a}{a}
\title{s}
\address{}{s}
\email{}
\phone[mobile]{1212}
\begin{document}
\cvitem{pie chart}{%
  \def\angle{0}
  \def\radius{3}
  \def\cyclelist{{"orange","blue","red","green"}}
  \newcount\cyclecount \cyclecount=-1
  \newcount\ind \ind=-1
  \begin{tikzpicture}[nodes = {font=\sffamily}]
    \foreach \percent/\name in {
      8/C++,8/Linux,7/Arduino,6/Python,6/Erlang,5/H5
    } {
      \ifx\percent\empty\else               % If \percent is empty, do nothing
      \global\advance\cyclecount by 1     % Advance cyclecount
      \global\advance\ind by 1            % Advance list index
      \ifnum3<\cyclecount                 % If cyclecount is larger than list
      \global\cyclecount=0              %   reset cyclecount and
      \global\ind=0                     %   reset list index
      \fi
      \pgfmathparse{\cyclelist[\the\ind]} % Get color from cycle list
      \edef\color{\pgfmathresult}         %   and store as \color
      % Draw angle and set labels
      \draw[fill={\color!50},draw={\color}] (0,0) -- (\angle:\radius) arc (\angle:\angle+\percent*1.8*2.5:\radius) -- cycle;
      \node at (\angle+0.5*\percent*1.8*2.5:0.7*\radius) {\name};
      \pgfmathparse{\angle+\percent*1.8*2.5}  % Advance angle
      \xdef\angle{\pgfmathresult}         %   and store in \angle
      \fi
    };
  \end{tikzpicture}%
}

\clearpage
\end{document}

但是，您真的不应该使用此代码。首先，它\color在大量使用颜色的环境中重新定义。重新定义只是局部的，但这仍然似乎令人怀疑。此外，它既充当局部变量，又充当接受参数的宏，这令人困惑。而且，定义不会抹去一些关键的东西这一点也\name并不明显。\global

此外，你不需要做任何这些危险的事情。以下做法应该更安全：

\documentclass[14pt,a4paper,san]{moderncv}
\moderncvstyle{classic}
\moderncvcolor{blue}
\name{a}{a}
\title{s}
\address{}{s}
\email{}
\phone[mobile]{1212}
\begin{document}

\cvitem{}{%
  \begin{tikzpicture}[font=\sffamily]
    % these are local - much less likely to cause problems
    \def\radius{3}
    \def\cyclelist{{"orange","blue","red","green"}}
    \foreach \percent/\pname [evaluate=\percent as \pangle using ((4.5*\percent)+\panglelast)) , remember=\pangle as \panglelast (initially 0), count=\cyclecount from 0] in 
    {
      8/C++,8/Linux,7/Arduino,6/Python,6/Erlang,5/H5
    } {
      \pgfmathsetmacro\mycolor{\cyclelist[(int(mod(\cyclecount,4)))]}
      % Draw angle and set labels
      \draw [fill={\mycolor!50}, draw={\mycolor}] (0,0) -- (\panglelast:\radius) arc (\panglelast:\pangle:\radius) -- cycle;
      \node at ({(\pangle+\panglelast)/2}:0.7*\radius) {\pname};
    };
  \end{tikzpicture}%
}

\end{document}

\cvitem并产生完全相同的结果（除了我在某处丢失了标签。

为了消除标签的挤压，您可能还喜欢类似以下内容的内容：

\documentclass[14pt,a4paper,san]{moderncv}
\moderncvstyle{classic}
\moderncvcolor{blue}
\name{a}{a}
\title{s}
\address{}{s}
\email{}
\phone[mobile]{1212}
\begin{document}

\cvitem{}{%
  \begin{tikzpicture}[font=\sffamily]
    % these are local - much less likely to cause problems
    \def\radius{3}
    \def\cyclelist{{"orange","blue","red","green"}}
    \foreach \percent/\pname [evaluate=\percent as \pangle using ((4.5*\percent)+\panglelast)) , remember=\pangle as \panglelast (initially 0), count=\cyclecount from 0] in 
    {
      8/C++,8/Linux,7/Arduino,6/Python,6/Erlang,5/H5
    } {
      \pgfmathsetmacro\mycolor{\cyclelist[(int(mod(\cyclecount,4)))]}
      % Draw angle and set labels
      \draw [fill={\mycolor!50}, draw={\mycolor}] (0,0) -- (\panglelast:\radius) arc (\panglelast:\pangle:\radius) -- cycle;
      \path (0,0) -- ({(\pangle+\panglelast)/2}:\radius) node [midway, sloped] {\pname};
    };
  \end{tikzpicture}%
}

\end{document}
