在 latex 中绘制图表

Question

我如何在乳胶中生成以下图表来说明鱼群搜索算法的行为？

Answer 1

使用您自己的数据而不是rnd：

\documentclass[border=2]{standalone}

\usepackage{pgfplots}
\pgfplotsset{compat=1.11}
\usetikzlibrary{fadings,backgrounds}

\pgfdeclareradialshading{rad}{\pgfpoint{0cm}{0cm}}%
{color(0cm)=(blue!50!black);
color(0.15cm)=(blue);
color(0.35cm)=(blue!80);
color(0.7cm)=(green);
color(1cm)=(yellow);
color(1.2cm)=(red);
color(1.25cm)=(black)}

\begin{document}
\begin{tikzpicture}
  \begin{axis}[
    enlargelimits,
    ]
    \addplot[scatter,only marks,mark=*,domain=0:1] {rnd};
    \begin{scope}[on background layer]
    %\path[opacity=0.8,shading=radial, inner color=blue,  outer color=red] (rel axis cs: 0,0) rectangle (rel axis cs: 1,1);
    \path[opacity=0.8,shading=rad] (rel axis cs: 0,0) rectangle (rel axis cs: 1,1);
    \end{scope}

  \end{axis}
\end{tikzpicture}
\end{document}
