绘制复数及其共轭

Question

我想在我的乳胶文档中绘制这个

：

我一直试图这样做，但总是出现错误，我不知道我的代码是否正确或者我是否缺少导入某些东西（我已经导入了 tikz）。

我一直在尝试使用 Matcha 工具复制图表，但无法得到我想要的结果。

    \tikzset{every picture/.style={line width=0.75pt}} %set default line width to 0.75pt         
\begin{tikzpicture}[x=0.75pt,y=0.75pt,yscale=-1,xscale=1]
%uncomment if require: \path (0,248); %set diagram left start at 0, and has height of 248

%Shape: Axis 2D [id:dp11352295339791363] 
\draw  (293.4,158) -- (393.4,158)(303.4,68) -- (303.4,168) (386.4,153) -- (393.4,158) -- (386.4,163) (298.4,75) -- (303.4,68) -- (308.4,75)  ;
%Straight Lines [id:da4318595895682128] 
\draw    (303.4,158) -- (341.96,109.17) ;
\draw [shift={(343.2,107.6)}, rotate = 128.3] [color={rgb, 255:red, 0; green, 0; blue, 0 }  ][line width=0.75]    (10.93,-3.29) .. controls (6.95,-1.4) and (3.31,-0.3) .. (0,0) .. controls (3.31,0.3) and (6.95,1.4) .. (10.93,3.29)   ;
%Straight Lines [id:da17611697180317232] 
\draw    (303.4,158) -- (341.36,194.61) ;
\draw [shift={(342.8,196)}, rotate = 223.96] [color={rgb, 255:red, 0; green, 0; blue, 0 }  ][line width=0.75]    (10.93,-3.29) .. controls (6.95,-1.4) and (3.31,-0.3) .. (0,0) .. controls (3.31,0.3) and (6.95,1.4) .. (10.93,3.29)   ;

\end{tikzpicture}

Answer 1

有了pstricks，代码就很短了：

    \documentclass[border=10pt, svgnames]{standalone}
    \usepackage{pst-eucl, pst-plot}

    \begin{document}

    \begin{pspicture}(-1,-2)(3,2)
    \psset{linejoin=1}
    \psaxes[labels=none, ticks=none](0,0)(-1,-2)(3,2)
    \pstGeonode[PointName={z,\bar z}](2; 40){z}(2; -40){z1}
    \psline[linestyle=dashed](z)(z1)
    \psline(z)(0,0)(z1)
    \end{pspicture}

    \end{document} 

Answer 2

你可以用 Mathcha 尝试一下这个可以正常工作的代码，

\documentclass[a4paper,12pt]{article}
\usepackage{tikz}


\begin{document}
\begin{center}
\tikzset{every picture/.style={line width=0.75pt}} %set default line width to 0.75pt        

\begin{tikzpicture}[x=0.75pt,y=0.75pt,yscale=-1,xscale=1]
%uncomment if require: \path (0,300); %set diagram left start at 0, and has height of 300

%Straight Lines [id:da10546756418707193] 
\draw  [dash pattern={on 4.5pt off 4.5pt}]  (269.7,60.55) -- (269.7,157.55) -- (269.7,200.05) ;

% Text Node
