Tikz：在弧线上列出文本

Question

我希望示例中的文本与圆圈对齐，我尝试decoration在示例的注释行中这样做，但没有效果。

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations.text}

\begin{document}
\begin{center}
\begin{tikzpicture}
    \foreach \x/\mes/\month[evaluate=\x as \y using \x*-30+120] in
        {
        1/Enero/January,
        2/Febrero/February,
        3/Marzo/March,
        4/Abril/April,
        5/Mayo/May,
        6/Junio/June,
        7/Julio/July,
        8/Agosto/August,
        9/Septiembre/September,
        10/Octubre/October,
        11/Noviembre/November,
        12/Diciembre/December
        }   {
        \draw (\y:5) -- ++(\y:0.4);
        \node [anchor=west,rotate=\y-90] at (\y:5.2) {\month};
        \node [anchor=west,rotate=\y-90] at (\y:5.6) {\mes};
        \draw   (\y:4.9) arc[start angle =\y, end angle=\y-20,radius=4.2];
%       \draw   (\y:4.9) arc[decorate,decoration={\month},start angle =\y, end angle=\y-20,radius=4.2];
        }

\end{tikzpicture}
\end{center}
\end{document}

一个简单的角度校正，对圆弧的切线进行测试：

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations.text}

\begin{document}
\begin{center}
\begin{tikzpicture}
    \foreach \x/\mes/\month[evaluate=\x as \y using \x*-30+120] in
        {
        1/Enero/January,
        2/Febrero/February,
        3/Marzo/March,
        4/Abril/April,
        5/Mayo/May,
        6/Junio/June,
        7/Julio/July,
        8/Agosto/August,
        9/Septiembre/September,
        10/Octubre/October,
        11/Noviembre/November,
        12/Diciembre/December
        }   {
        \draw (\y:5) -- ++(\y:0.4);
        \node [anchor=south,rotate=\y-100] at (\y-10:5) {\month}; % <---
        \node [anchor=south,rotate=\y-100] at (\y-10:5.4) {\mes}; % <---
        \draw   (\y:4.9) arc[start angle =\y, end angle=\y-20,radius=4.8];
        }
\end{tikzpicture}
\end{center}
\end{document}

使用 TikZ 库decorations.text可以用文本装饰路径：

编辑：文本现在左对齐，2pt左侧有小缩进（），文本开头不接触径向线：

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations.text}

\begin{document}
\begin{center}
\begin{tikzpicture}[
    decoration={text along path,
    text align={left,left indent=2pt}}]
    \foreach \x/\mes/\month[evaluate=\x as \y using \x*-30+120] in
        {
        1/Enero/January,
        2/Febrero/February,
        3/Marzo/March,
        4/Abril/April,
        5/Mayo/May,
        6/Junio/June,
        7/Julio/July,
        8/Agosto/August,
        9/Septiembre/September,
        10/Octubre/October,
        11/Noviembre/November,
        12/Diciembre/December
        }   {
        \draw (\y:5) -- ++ (\y:0.4);
        \draw   (\y:4.9) arc[start angle =\y, end angle=\y-20,radius=4.8];

        \draw [decorate,
               decoration={text={\mes}}]               
               (\y:5)  arc [start angle =\y, end angle=\y-20,radius=4.8];
        \draw [decorate,
               decoration={text={\mes}}]
               (\y:5.4)  arc [start angle =\y, end angle=\y-20,radius=4.8];
        }
\end{tikzpicture}
\end{center}
\end{document}
