I make some experiments with \pgfkeys after the Qrrbrbirlbel's answer to this question

The first try is :

\documentclass{scrartcl}
\usepackage{tikz}
\begin{document}
\pgfkeys{/swatch/.code={\node[fill=white] at (m.90-30*#1) {#1};}}

  \begin{tikzpicture}
    \node[circle,minimum size=4cm,draw] (m) {};
    \pgfkeys{/swatch/.list={1,...,12}}
  \end{tikzpicture}
\end{document}

and the result is :

\foreach is very fine to get the same result but It was funny to try.

Now I would like to know if it's possible to do something like this to add multiple labels

\documentclass{scrartcl}
\usepackage{tikz}
\begin{document}

  \begin{tikzpicture}
    \node[circle,minimum size=4cm,draw,label=90:12,label=0:3,label=-90 :6,label=-180:9] (m) {};
  \end{tikzpicture}
\end{document}

Code

\documentclass{scrartcl}
\usepackage{tikz}
\makeatletter % http://tex.stackexchange.com/a/106796/16595
\tikzset{anchor/.append code=\let\tikz@auto@anchor\relax}
\makeatother
\tikzset{
    clock hours/.style={
        label={[fill=white,anchor=center]-(30*#1-90):#1}}
}
\begin{document}
    \begin{tikzpicture}
    \node[circle,minimum size=4cm,draw,clock hours/.list={1,...,12}] (m) {};
    \end{tikzpicture}
\end{document}

Output

  • Very fine, I am very impressed with your speed and style of your answers – Alain Matthes Apr 09 '13 at 10:12
  • @AlainMatthes I’ll try my best. Though, I just noticed that TikZ does evaluate the angle parameter of the label key anyway, so we can just use label={[…]-(30*#1-90):#1}. No need for a .code handler. – Qrrbrbirlbel Apr 09 '13 at 10:23
