将百分比符号放在 x 轴上

Question

如何在 x 轴上放置百分比“%”符号？

\documentclass{standalone}

\pgfdeclareplotmark{mystar}{
    \node[star,star point ratio=2.25,minimum size=6pt,
    inner sep=0pt,draw=black,solid,fill=red] {};
}

\decimalpoint

一种方法是将以下内容添加到命令的可选参数中\begin{axis}：

    xticklabel={$\pgfmathprintnumber{\tick}\%$},

注意——根据上面的 MWE，轴文本是西班牙语。
