条形图 - 在条形上插入文本

Question

我想使用这个乳胶模块（复制自这里）绘制条形图。

\newcounter{barcount}


% draw a bar chart
% param 1: width
% param 2: height
% param 3: border color
% param 4: label text color
% param 5: label bg color
% param 6: cat 1 color
\newenvironment{barchart}[8]{

    \newcommand{\barwidth}{0.35}
    \newcommand{\barsep}{0.2}

    % param 1: overall percent
    % param 2: label
    % param 3: cat 1 percent
    % param 4: cat 2 percent
    % param 5: cat 3 percent
    \newcommand{\baritem}[5]{

        \pgfmathparse{##3+##4+##5}
         \let\perc\pgfmathresult

        \pgfmathparse{#2}
         \let\barsize\pgfmathresult

        \pgfmathparse{\barsize*##3/100}
         \let\barone\pgfmathresult

        \pgfmathparse{\barsize*##4/100}
         \let\bartwo\pgfmathresult

        \pgfmathparse{\barsize*##5/100}
         \let\barthree\pgfmathresult

        \pgfmathparse{(\barwidth*\thebarcount)+(\barsep*\thebarcount)}
         \let\barx\pgfmathresult

        \filldraw[fill=#6, draw=none] (0,-\barx) rectangle (\barone,-\barx-\barwidth);
        \filldraw[fill=#7, draw=none] (\barone, -\barx) rectangle (\barone+\bartwo,-\barx-\barwidth);
        \filldraw[fill=#8, draw=none] (\barone+\bartwo,-\barx ) rectangle (\barone+\bartwo+\barthree,-\barx-\barwidth);

        \node [label=180:\colorbox{#5}{\textcolor{#4}{##2}}] at (0,-\barx-0.175) {};
        \addtocounter{barcount}{1}
    }
    \begin{tikzpicture}
    \setcounter{barcount}{0}

}
{\end{tikzpicture}}

它的用法如下：

\begin{barchart}{10}{16}{sectcol}{textcol}{sectcol}{maincol}{secondcol}{thirdcol}
    \baritem{100}{Python}{20}{20}{0}
\end{barchart}

现在我需要的是在栏上写文字。如下所示：

是否可以更改模块来实现这一点？

提前致谢

Answer 1

我建议使用 pgf 键，而不是使用具有最多 8 个强制参数的环境和宏。然后代码简化为

\begin{barchart}
  \baritem{Python}{40/scipy,40/scikit-learn}
  \baritem{R}{40/tidywise}
  \baritem{Pft}{30/hibernate,30/sleep,40/eat}
\end{barchart}

但您仍然可以通过更改 pgf 键（其初始值或可选参数）来完全控制外观。以下是完整的 MWE（这是此网站上代码通常共享的方式）：

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning}
\newcounter{barcount}
\tikzset{barchart/.cd,y distance/.initial=3em,
bar height/.initial=2em,width/.initial=6cm,
bar text/.style={font=\sffamily,text depth=0.25em},
description/.style={font=\sffamily,text depth=0.25em},
colors/.initial={"orange!80","blue!40","red","green!70!black"}}
\newenvironment{barchart}[1][]{%
    \tikzset{barchart/.cd,#1}%
    \newcommand{\baritem}[2]{\stepcounter{barcount}%
     \path (0,-\number\value{barcount}*\pgfkeysvalueof{/tikz/barchart/y distance})
      coordinate (tmp) node[left=1ex,yshift=\pgfkeysvalueof{/tikz/barchart/bar
      height}/2,/tikz/barchart/description]{##1};
     \foreach \Percentage/\Text [count=\X starting from 0]  in {##2}
     {\pgfmathsetmacro{\mycolor}{{\pgfkeysvalueof{/tikz/barchart/colors}}[\X]}
     \path[fill=\mycolor] (tmp)      rectangle ++ 
       ({(\Percentage/100)*\pgfkeysvalueof{/tikz/barchart/width}},
     \pgfkeysvalueof{/tikz/barchart/bar height}) 
     node[midway,/tikz/barchart/bar text]{\Text};
     \path (tmp) + ({(\Percentage/100)*\pgfkeysvalueof{/tikz/barchart/width}},0)
      coordinate(tmp); }
    }
    \begin{tikzpicture}
    \setcounter{barcount}{0}}
{\end{tikzpicture}}
\begin{document}

\begin{barchart}
  \baritem{Python}{40/scipy,40/scikit-learn}
  \baritem{R}{40/tidywise}
  \baritem{Pft}{30/hibernate,30/sleep,40/eat}
\end{barchart}
\end{document}
