如何在標記的 pgfplots 路徑上顯示文字？

Question

我正在使用該decorations.text庫沿著繪製的路徑設置文本pgfplots。裝飾效果很好，沒有痕跡，如建議的那樣這個答案，但路徑上有標記，編譯失敗並顯示Package pgf Error: I cannot decorate an empty path \end{axis}.為什麼，有解決方法嗎？

\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.11}
\usetikzlibrary{decorations.text}
\begin{document}
\begin{tikzpicture}
\begin{axis}
\addplot+[
    no markers,
    decoration={
        text along path,
        text={This is my path},
    },
    postaction={decorate},
] coordinates {(0,0) (10,1)};
% \addplot+[
%     mark=*,
%     decoration={
%     text along path,
%     text={This is my path},
%     },
%     postaction={decorate},
% ] coordinates {(0,1) (10,0)}; %This one fails
\end{axis}
\end{tikzpicture}
\end{document}

Answer 1

您可以使用以下命令停用標記裝飾來解決該問題mark options={decoration={name=none}}：

\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.11}
\usetikzlibrary{decorations.text}

\begin{document}
\begin{tikzpicture}
\begin{axis}
\addplot+[
    no markers,
    decoration={
        text along path,
        text={This is my path},
    },
    postaction={decorate},
] coordinates {(0,0) (10,1)};
 \addplot+[
     mark=*,
     decoration={
     text along path,
     text={This is my path},
     },
     mark options={decoration={name=none}},
     postaction={decorate},
 ] coordinates {(0,1) (10,0)}; %This one fails
\end{axis}
\end{tikzpicture}
\end{document}
