修改 arcarrow

我在这里找到了这个 PDCA 循环（计划、执行、检查、行动）

我怎样才能去除箭头形状并采取简单的曲线矩形？ 在此处输入图片描述

也就是说，我想删除产生拼图效果和首选方向的弧形箭头对象的起点和终点。

写下答案可能比将信息分散在太多评论中更加清晰。

\documentclass[tikz,border=10pt]{standalone}
\usetikzlibrary{decorations.text}
\definecolor{mygray}{RGB}{208,208,208}
\definecolor{mymagenta}{RGB}{226,0,116}
\newcommand*{\mytextstyle}{\sffamily\Large\bfseries\color{black!85}}
\begin{document}
\begin{tikzpicture}
   \fill[mymagenta] circle (1.35);
   \node at (0,0) [
      font  = \mytextstyle,
      color = white,
      align = center
   ]{
      PDCA\\
      Cycle
   };
   \pgfmathsetmacro{\mydist}{2}
   \pgfmathsetmacro{\Radius}{2}
    \foreach \X [count=\Y] in {PLAN,DO,CHECK,ACT}
    {\pgfmathtruncatemacro{\itest}{sign(sin(180-\mydist-90*\Y))}
    \ifnum\itest>0
    \draw[mygray,line width=1cm,postaction={decoration = {
         text along path,
         text = {|\mytextstyle|\X},
         text align = {align = center},
         raise = -1.0ex
      },
      decorate}] (180-\mydist-90*\Y:\Radius) arc(180-\mydist-90*\Y:90+\mydist-90*\Y:\Radius);
    \else
    \draw[mygray,line width=1cm,postaction={decoration = {
         text along path,
         text = {|\mytextstyle|\X},
         text align = {align = center},

      },
      decorate}] (90+\mydist-90*\Y:\Radius) arc(90+\mydist-90*\Y:180-\mydist-90*\Y:\Radius);

答案2

这轮图我写的包，可以使用。

初始设置为value=\WCvarA、slices style=\WCvarB和data=\WCvarC。对于此图，我们设置value=1为使每个切片具有相同的大小。我们还将键设置data为空。

弧线中的文本由键指定。此文本的方向取决于键中使用的arc data弧线中间的角度。此文本的位置由键决定。\WCmidanglearc data dirarc data pos

切片之间的间隙是通过密钥获得的gap。

\usepackage{wheelchart}
\usetikzlibrary{decorations.text}
\definecolor{mygray}{RGB}{208,208,208}

\begin{document}
\begin{tikzpicture}

\fill[mymagenta] (0,0) circle[radius=1.5];
\wheelchart[
  arc data=\WCvarA,
  arc data dir={\WCmidangle<180?1:-1},
