饼图中的隐藏数字

想要提取饼图中隐藏或不清楚的数字，并将它们显示为附图中的“带线的红色数字”。以下是我的代码

\documentclass[acmsmall]{acmart}
\acmJournal{CSUR}

\usepackage{tikz,pgfplots,pgfplotstable}
\usepackage{graphicx}
\usepackage{pgf-pie, etoolbox} 

\begin{document}

\begin{figure*}[h]
\centering
\captionsetup{justification=centering}
\begin{tikzpicture}

您可能更愿意使用另一种方式来绘制饼图，因为该pgf-pie包在自定义方面不太灵活。话虽如此，我在原始包中添加了一些相关功能，增加了一些选项（目前仅影响样式polar）：

  • number as pin if below（默认值0）：如果数字的相关值低于给定的阈值，则将数字的样式更改为大头针；
  • shift label if below（默认值0）：如果数字的相关值低于给定的阈值，则将标签向外移动；
  • shift label（默认值0pt）：按给定值将标签向外移动。

通过这些更改，可以执行以下操作：

\documentclass[border=10pt]{standalone}
\usepackage{pgf-pie} 

\begin{document}
\begin{tikzpicture}[
    scale=0.6,
    font={\scriptsize},
    pin distance=2mm,
    pin edge={red},
    every pin/.style={
        red,
        inner sep=2pt
    }
]
\pie[
    polar, 
    explode=.1, 
    number as pin if below=5, 
    shift label if below=5, 
    shift label=20pt
]{
    1/2016,
    6/2017,
    13/2018,
    12/2019,
    16/2020,
    21/2021,
    35/2022
}
\end{tikzpicture}
\end{document}

该文件tikzlibrarypie.code.tex需要修改如下：

  1. 将的定义替换为\pgfpie@slice：

    \def\pgfpie@slice#1#2#3#4#5#6#7#8{%
  \pgfmathparse{0.5*(#1)+0.5*(#2)}
  \let\pgfpie@midangle\pgfmathresult

  \path (#8) -- ++({\pgfpie@midangle}:{#5}) coordinate (pgfpie@O);

  \pgfmathparse{(#7)+(#5)}
  \let\pgfpie@radius\pgfmathresult

  % slice
  \draw[line join=round,fill={#6},\pgfpie@style] (pgfpie@O) -- ++({#1}:{#7}) arc ({#1}:{#2}:{#7}) -- cycle;

  \pgfpie@ifchangedirection{%
    \pgfmathparse{min(((#1)-(#2)-10)/110*(-0.3),0)}
  }{%
    \pgfmathparse{min(((#2)-(#1)-10)/110*(-0.3),0)}
  }%

  \pgfmathparse{(max(\pgfmathresult,-0.5) + 0.8)*(#7)}
  \let\pgfpie@innerpos\pgfmathresult

  \pgfpie@ifx\pgfpie@text\pgfpie@text@inside{%
    % label and number together
    \path (pgfpie@O) -- ++({\pgfpie@midangle}:{\pgfpie@innerpos}) node[align=center]
    {\pgfpie@scalefont{#3}\pgfpie@labeltext{#4}\\\pgfpie@numbertext{#3}};
  }{%
    % label
    \pgfpie@ifhidelabel{}{%
      \pgfpie@iflegend{}{%
        \pgfpie@ifnum{#3}{<}{\pgfpie@shiftlabelthreshold}{%
          \pgfmathsetlength{\pgfpie@shiftLabelDist}{\pgfpie@shiftlabel}
        }{
          \pgfmathsetlength{\pgfpie@shiftLabelDist}{0pt}
        }
        \path (pgfpie@O) -- ++({\pgfpie@midangle}:{\pgfpie@radius})
        node[inner sep=0, \pgfpie@text={[shift={(\pgfpie@midangle:\pgfpie@shiftLabelDist)}]\pgfpie@midangle:#4}] {};
      }%
    }%

    % number
    \pgfpie@ifnum{#3}{<}{\pgfpie@numberpinthreshold}{%
      \path (pgfpie@O) -- ++({\pgfpie@midangle}:{\pgfpie@innerpos}) 
      node[pin={\pgfpie@midangle:{\pgfpie@scalefont{#3}\pgfpie@numbertext{#3}}}] {};
    }{%
      \path (pgfpie@O) -- ++({\pgfpie@midangle}:{\pgfpie@innerpos}) 
      node {\pgfpie@scalefont{#3}\pgfpie@numbertext{#3}};
    }%
  }%
}

  2. 添加\newdimen\pgfpie@shiftLabelDist其他尺寸的定义位置。

  3. 添加以下选项到\pgfqkeys{/pgfpie}：

    number as pin if below/.store in=\pgfpie@numberpinthreshold,
shift label if below/.store in=\pgfpie@shiftlabelthreshold,
shift label/.store in=\pgfpie@shiftlabel,

  4. 添加以下选项到\pgfqkeys{/pgfpie}：

    number as pin if below/.store in=\pgfpie@numberpinthreshold,
shift label if below/.store in=\pgfpie@shiftlabelthreshold,
shift label/.store in=\pgfpie@shiftlabel,

  5. 替换定义\pgfpie@@pie（作为包装\scope宏的选项）：

    number as pin if below=0,
shift label if below=0,
shift label=0pt,

您可以使用etoolbox修补原始宏：

\documentclass[border=10pt]{standalone}
\usepackage{pgf-pie, etoolbox}

\patchcmd{\pgfpie@slice}{

    }%

答案2

在此处输入图片描述

我尝试从头开始创建图表作为pic元素。pie它的第二个参数是比例；它可能会直接在本地缩放 pic 元素，但在我的测试中这并不令人信服。

答案3

以下答案使用轮图包，是我写的。

请注意，原始问题中的一些百分比是错误的：2020 年应该是 15% 而不是 16%；2021 年应该是 20% 而不是 21%；2022 年应该是 34% 而不是 35%。

切片通过键进行移动explode。

使用键值对来指定颜色列表WClistcolors。这些颜色可以与宏一起使用\WClistcolors。

定义一个命令\WCtest，其输出取决于第一个变量是否小于 5。此命令用于键data、lines和wheel data。
