如何隐藏 pst-plot 绘制的图形中的 x 轴和 y 轴上的坐标

Question

以下代码取自从这个答案

\documentclass[border=0bp]{standalone}

\usepackage{pst-plot}

\begin{document}

\psset{unit=1.5cm}
\begin{pspicture}[showgrid=false](-2.75,-0.75)(4,2)
    \psframe*[linecolor=yellow,opacity=0.5](-2.75,-0.75)(4,2)
    \psaxes[linecolor=lightgray]{->}(0,0)(-2.5,-0.5)(3.5,1.5)[$t$,0][$F(t)$,90]
    \psset{algebraic,linewidth=1.5pt,linecolor=red}
    \pscustom
    {
        \psplot{-2.5}{-1}{0}
        \psplot{-1}{0}{(x+1)/4}
        \psplot{0}{1}{1/2}
        \psplot{1}{2}{(x+7)/12}
        \psplot{2}{3.5}{1}
    }
\end{pspicture}

\end{document}

我想知道如何隐藏 x 和 y 轴上的数字和小垂直线？我只想要带箭头的线。

Answer 1

您应该将选项ticks和添加labels到\psaxes宏中。选项可以采用不同的键，例如all、none和。例如，使用将隐藏所有刻度和所有标签。使用将仅在 y 轴上显示刻度和标签。有关此类选项的x更多信息，我建议查看yticks=none, labels=noneticks=y, labels=y手动的。
