显示奇数

Question

我怎样才能显示奇数xticklabels？

代码：

\documentclass[margin=3mm]{standalone}
\usepackage[english,spanish]{babel}         % multilenguaje
\usepackage{pgfplots}
\usetikzlibrary{babel,
    positioning}
\pgfplotsset{compat=1.16,width=0.98\linewidth}



\usepackage{filecontents}
\begin{filecontents}{performance.data}
    x    A       B         C        D        E         F

\end{filecontents}
\decimalpoint


\begin{document}
    \begin{tikzpicture}
    \begin{axis}[
    grid = none,
    legend style={at={(0.97,0.03)}, anchor=south east, draw=black},

    mark size=1.3pt,
    cycle list={

        {black,mark=*},
        {red,mark=*},
        {green,mark=*},
        {orange,mark=*},
        {cyan,mark=*},% <-- don't add a comma here
    },
    ]
    \addplot    table [y=A] {performance.data};
    \addlegendentry{20 f}
    \addplot    table [y=B] {performance.data};

Answer 1

将评论转换为答案。

您可以xticks像这样手动提及：

xtick={0.01,0.03,...,0.20},

这样就只会显示奇数个刻度。

结果：
