Pgfplots-条件样式

Question

我想为我的pgfplots图表创建一个条件样式，该样式将根据输入值使用这种或那种基本样式。

这是一个取决于 numplots 值的条件样式的示例，问题是我不知道如何实现条件，因为命令\numplots无法识别\ifthenelse{...}。 有可能解决这个问题吗？

\documentclass{standalone}
\usepackage{pgfplots, ifthen}

\pgfplotsset{
    MyList-1/.style={
        cycle list={
            red, mark=*\\
        },
    },
    MyList-2/.style={
        cycle list={
            blue, mark=*\\%
            red, mark=*\\%
        },
    },
    MyList-3/.style={
        cycle list={
            green, mark=*\\%
            red, mark=*\\%
            blue, mark=*\\%
        },
    },
    MyList-4/.style={
        cycle list={
            red, mark=*\\%
            black, mark=*\\%
            green, mark=*\\%
            purple, mark=*\\%
        },
    },
    MyList-5/.style={
        cycle multiindex* list={
            blue\\%
            yellow\\%
            orange\\%
            red\\%
            green\\%
            \nextlist
            mark=*\\
            mark=square*\\
        },
    },
    MyList-6/.style={
        cycle multiindex* list={
            teal\\%
            violet\\%
            red\\%
            magenta\\%
            blue\\%
            brown\\%
            \nextlist
            mark=*\\
            mark=square*\\
        },
    },
    MyListChoice/.code={%
            \ifthenelse{\equal{\numplots}{1}}{MyList-1}{
            \ifthenelse{\equal{\numplots}{1}}{MyList-2}{
            \ifthenelse{\equal{\numplots}{1}}{MyList-3}{
            \ifthenelse{\equal{\numplots}{1}}{MyList-4}{
            \ifthenelse{\equal{\numplots}{1}}{MyList-5}{
            \ifthenelse{\equal{\numplots}{1}}{MyList-6}{
            }}}}}}
    },
}

\begin{document}
\begin{tikzpicture}
    \begin{axis}[MyListChoice]
        \addplot coordinates {(0,0)(1,1)};
        \addplot coordinates {(1,0)(2,1)};
        \addplot coordinates {(2,0)(3,1)};
        \addplot coordinates {(3,0)(4,1)};
    \end{axis}
\end{tikzpicture}

我认为您正在寻找/.is choice密钥处理程序。

\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.17}
\pgfplotsset{MyList/.is choice,
    MyList/1/.style={
        cycle list={
            red, mark=*\\
        },
    },
    MyList/2/.style={
        cycle list={
            blue, mark=*\\%
            red, mark=*\\%
        },
    },
    MyList/3/.style={
        cycle list={
            green, mark=*\\%
            red, mark=*\\%
            blue, mark=*\\%
        },
    },
    MyList/4/.style={
        cycle list={
            red, mark=*\\%
            black, mark=*\\%
            green, mark=*\\%
            purple, mark=*\\%
        },
    },
    MyList/5/.style={
        cycle multiindex* list={
            blue\\%
            yellow\\%
            orange\\%
            red\\%
            green\\%
            \nextlist
            mark=*\\
            mark=square*\\
        },
    },
    MyList/6/.style={
        cycle multiindex* list={
            teal\\%
            violet\\%
            red\\%
            magenta\\%

            brown\\%
            \nextlist
            mark=*\\
            mark=square*\\
        },
    },
}

\begin{document}
\begin{tikzpicture}
    \begin{axis}[MyList=2]
        \addplot coordinates {(0,0)(1,1)};
        \addplot coordinates {(1,0)(2,1)};
        \addplot coordinates {(2,0)(3,1)};
        \addplot coordinates {(3,0)(4,1)};
    \end{axis}
\end{tikzpicture}

\begin{tikzpicture}
    \begin{axis}[MyList=4]
        \addplot coordinates {(0,0)(1,1)};
        \addplot coordinates {(1,0)(2,1)};
