顯示奇數

Question

如何在 上顯示奇數xticklabels？

程式碼:

\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}

Answer 1

將評論轉換為答案。

您可以xticks像這樣手動提及：

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

這樣只會顯示奇數刻度。
