Modifying arcarrow

Question

I have found this PDCA cycle (plan, do, check, act) here

http://www.texample.net/tikz/examples/pdca-cycle/

% PDCA cycle

      -- (\astart:\rmid) -- cycle;
   \path[
      decoration = {
         text along path,
         text = {|\mytextstyle|#3},

         raise = -1.0ex
      },
      decorate
   ](\astart+\atip:\rmid) arc (\astart+\atip:\aend+\atip:\rmid);
}
\begin{document}
\begin{tikzpicture}
   \fill[even odd rule,mymagenta] circle (1.5);

   \node at (0,0) [
      font  = \mytextstyle,
      color = white,
      align = center
   ]{
      PDCA\\
      Cycle
   };
   \arcarrow{ 85}{  3}{ PLAN  }
   \arcarrow{270}{357}{ DO    }
   \arcarrow{182}{269}{ CHECK }
   \arcarrow{176}{ 96}{ ACT   }
\end{tikzpicture}
\end{document}

How can I remove the arrow-like shape and take a simple curved-like rectangle?

That is I want to remove the start and the end of the arcarrow object that gives rise to the puzzle effect and a preferred orientation.

What is a curved-like rectangle? Could you perhaps add a sketch? — , Apr 19 '19 at 23:41
@marmot Thanks for the comment. I apologize for not being clear. The plan, do, check, act text are inside arrow-like shapes thanks to the command \arcarrow. I just want to modify slightly the stard and the end of these shapes in order that there is not preferred sense or stating differently removing the puzzle-like effect. — Dimitris, Apr 19 '19 at 23:48
For that you only need to modify the \fill command to become \fill[mygray, very thick] (\astart+\atip:\rin) arc (\astart+\atip:\aend:\rin) -- (\aend:\rout) arc (\aend:\astart+\atip:\rout) -- cycle;, i.e. drop two coordinates from that path. — , Apr 19 '19 at 23:51
@marmot It's almost there! Thank you very much. Is it possible to decrease the distance between the previous end and the following start? — Dimitris, Apr 19 '19 at 23:54
@marmot I found it on my own! Just one thing how is possible to change the circle radious to 2 (I know that) but keep the distance of the curved shapes to the circle as it was? — Dimitris, Apr 19 '19 at 23:59

it might be cleaner to write an answer than scattering the information over too many comments.

\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},

      },

It's amazing! But the orientation of Do and Check text is reversed (pi rad). – Dimitris Apr 20 '19 at 00:06
@Dimitris Good catch! Fixed it. – Apr 20 '19 at 00:10
I don't know if I should open a new thread but when I type something like \foreach \X [count=\Y] in {Déplacement,Vélocité, Rapidité, Dépa} the words appears without the accents even though the preambule contains french babel loading. I tried also D\'{e}pa but still the behavior rests the same. – Dimitris Apr 20 '19 at 10:05
@Dimitris When using decorations.text, one has to "protect" these characters. E.g. \foreach \X [count=\Y] in {PLAN,DO,CHECK,D{\'{e}}pa} ... works because there are { and } around this symbol, see e.g. https://tex.stackexchange.com/q/481935/121799 for a related problem. – Apr 20 '19 at 13:57
TeX SE is better than a book about LaTeX. Thank you very much once again! I did as you said and everything is ok! – Dimitris Apr 20 '19 at 14:15

The wheelchart package, which I wrote, can be used.

The initial settings are value=\WCvarA, slices style=\WCvarB and data=\WCvarC. For this figure, we set value=1 so that each slice is the same size. We also set the key data empty.

The text in the arcs is given to the key arc data. The direction of this text depends on the angle of the middle of the arc given by \WCmidangle which is used in the key arc data dir. The position of this text is determined by the key arc data pos.

The gaps between the slices are obtained with the key gap.

\documentclass[border=6pt]{standalone}
\usepackage{wheelchart}
\usetikzlibrary{decorations.text}
\definecolor{mygray}{RGB}{208,208,208}
\definecolor{mymagenta}{RGB}{226,0,116}
\begin{document}
\begin{tikzpicture}
\sffamily\Large\bfseries\color{black!85}
\fill[mymagenta] (0,0) circle[radius=1.5];
\wheelchart[
  arc data=\WCvarA,
  arc data dir={\WCmidangle<180?1:-1},
  arc data pos=0.5,
  data=,
  gap,
  middle=PDCA\\Cycle,
  radius={1.7}{2.7},
  slices style=mygray,
  value=1
]{PLAN,DO,CHECK,ACT}
\end{tikzpicture}
\end{document}

Thank you very much! Wow, more than four year ago. I have totally forgotten my question. I really appreciate your answer! — Dimitris, Dec 20 '23 at 12:52
