四边都有坐标的网格？

四边都有坐标的网格？

这是对这个相当惊人的答案的增强请求 循环空间： 如何在 TikZ 中自动按网格显示坐标？。

这个答案给出了在页面上放置网格的方法，其坐标位于左侧和底部。我想要一个增强的方法，其坐标也位于右侧和顶部。我更喜欢直接基于 Loop Space 答案的答案，但我想其他选择也可以。

我问这个问题的原因是我想使用坐标网格进行注释。如果两边都有坐标，注释会更容易，因为坐标会更容易看到。例如，我对“使用免费软件为 PDF 文件添加文本注释和图像”的回答。

是的，只需进行微创手术。

\documentclass[tikz,border=3.14mm]{standalone}

您还可以添加is if键以使内容更易于自定义。这将产生与上面相同的输出：

\begin{document}

\begin{tikzpicture}

但如果你这么做了，说

\begin{tikzpicture}
\draw (-2,-2) to[grid with coordinates,ticks on top=true,ticks right=true,
ticks at bottom=false] (7,4);
\end{tikzpicture}

最初，左侧和底部的勾号为真，而其他的为假，这样如果您不添加任何这些键，您就会重现原始答案的输出。

PSTricks 解决方案仅供娱乐。有人偷了0水平轴上的标签。

\documentclass[pstricks,border=1cm,12pt]{standalone}
\usepackage{pst-plot}
\begin{document}
\pspicture[xticksize=-5 5,yticksize=-5 5,subticks=5,subticksize=1,axesstyle=none](-5,-5)(5,5)
    \psaxes(0,0)(-5,-5)(5,5)
    \psaxes[xlabelPos=top,ylabelPos=right](0,0)(-5,-5)(5,5)
\endpspicture
\end{document}
