删除函数图中的节点连续性 - Tikz

Question

所以我有这个图表

我想要的是删除连接节点的那些线。换句话说，我想让函数不连续。这是我的代码：

\documentclass[a4paper]{article}
\usepackage[spanish]{babel}
\usepackage[utf8]{inputenc}
\usepackage{fullpage} % Package to use full page
\usepackage{parskip} % Package to tweak paragraph skipping
\usepackage{tikz} % Package for drawing
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{hyperref}
\usepackage{graphicx}
\usepackage{eucal}
\usepackage{algorithm}
\usepackage{float}
\usepackage{forest}
\usepackage{pgfplotstable}
\usepackage{pgfplots}
\usepackage[shortlabels]{enumitem}
\begin{document}

\pgfplotstableread[col sep=comma]{tiempos-ej3.csv}{\table}
\begin{figure}[H]
\centering
\begin{tikzpicture}
\begin{axis}[
  xlabel= $n$,
  ylabel=  $\frac{\text{Tiempo}}{n^2 log(n)}$ (ns), 
  ymax = 2*(10^4)]
\addplot+[thin,mark size=1pt] table[x = cant_ejes, y expr = {\thisrow{ns_rutas_vacias}/(\thisrow{cant_ejes}^2)*log2(\thisrow{cant_ejes})} , col sep=comma]{\table};
\addlegendentry{G vac\'{i}o}

`\end{axis}
\end{tikzpicture}
\end{figure}

\end{document}

---

编辑

我正在使用的数据（tiempos-ej3.csv)：

cant_ejes, ns_rutas_completas, ns_rutas_vacias, ns_rutas_esparso_conexo, ns_rutas_esparso_disconexo, ns_rutas_denso_conexo, ns_rutas_denso_disconexo

Answer 1

您没有提供数据，所以我使用了随机点。如注释中所示，添加only marks到轴规范中。

\documentclass{article}
\usepackage{amsmath,pgfplots}
\begin{document}
\begin{tikzpicture}
  \begin{axis}[
    only marks,
    xlabel=$n$,
    ylabel=$\frac{\text{Tiempo}}{n^2 log(n)}$ (ns), 
    ymax = 2*(10^4)]
    \addplot+[thin,mark size=1pt,samples=300] {1.9e4*rnd};
    \addlegendentry{G vac\'{i}o}
  \end{axis}
\end{tikzpicture}
\end{document}
