使 psdot 宽度变粗

Question

我正在尝试创建一条数字线，但 psdot 不够粗或不够厚，它应该与箭头的宽度相同。

线宽似乎没有帮助，这是完整的代码。

\begin{figure}[H]
\psset{xunit=1.0cm,yunit=1.0cm,algebraic=true,dimen=middle,dotstyle=o,dotsize=3pt 0,linewidth=0.8pt,arrowsize=3pt 2,arrowinset=0.25}
\begin{pspicture*}(-4.3,-3.12)(7.3,6.3)
\psline{->}(0.,0.)(6.,0.)
\psline(1.,0.2)(1.,-0.2)
\psline(1.,0.2)(1.,-0.2)
\psline(1.,0.2)(1.,-0.2)
\psline(2.,0.2)(2.,-0.2)
\psline(3.,0.2)(3.,-0.2)
\psline(4.,0.2)(4.,-0.2)
\psline(5.,-0.2)(5.,0.2)
\rput[tl](2.94,-0.3){5}
\rput[tl](1.94,-0.3){4}
\rput[tl](0.94,-0.32){3}
\rput[tl](3.94,-0.3){6}
\rput[tl](4.94,-0.32){7}
\psline{->}(2.98,0.42)(4.98,0.42)
\psdots[linewidth=8pt,dotsize=5pt 0](2.98,0.42)
\end{pspicture*}
\end{figure}

Answer 1

我不认为厚度\psdots可以改变（见https://tex.stackexchange.com/a/73087/27635）。

您可以将一个放置\pscircle在其上方，作为一种解决方法。

\documentclass{article}

\usepackage{pstricks}

\begin{document}
\begin{figure}[H]
\psset{xunit=1.0cm,yunit=1.0cm,algebraic=true,dimen=middle,dotstyle=o,linewidth=0.8pt,arrowsize=3pt 2,arrowinset=0.25}
\begin{pspicture*}(-4.3,-3.12)(7.3,6.3)
\psline{->}(0.,0.)(6.,0.)
\psline(1.,0.2)(1.,-0.2)
\psline(1.,0.2)(1.,-0.2)
\psline(1.,0.2)(1.,-0.2)
\psline(2.,0.2)(2.,-0.2)
\psline(3.,0.2)(3.,-0.2)
\psline(4.,0.2)(4.,-0.2)
\psline(5.,-0.2)(5.,0.2)
\rput[tl](2.94,-0.3){5}
\rput[tl](1.94,-0.3){4}
\rput[tl](0.94,-0.32){3}
\rput[tl](3.94,-0.3){6}
\rput[tl](4.94,-0.32){7}
\psline{->}(2.98,0.42)(4.98,0.42)
\psdots[dotsize=5pt 0](2.98,0.42)
\pscircle(2.98,0.42){2.5pt}
\end{pspicture*}
\end{figure}
\end{document}

有一个可选参数arrowLW（arrowLineWidth）

\documentclass{article}
\pagestyle{empty}
\usepackage{pst-plot}
\begin{document}

\psset{linewidth=0.8pt,arrowsize=3pt 2,arrowinset=0.25}
\begin{pspicture*}(-1,-1)(8,1)
\psaxes[yAxis=false,Ox=3]{->}(0,0)(-0.9,0)(5,0)
\psline[arrowscale=1.5,arrowLW=2pt]{o->}(2,0.42)(4,0.42)
\end{pspicture*}

\end{document}
