情况1

轴中的标签y是的倍数，\frac{\sqrt{3}}{3}而轴中的标签x是的倍数\frac{\pi}{4}。

我想将 axis 重命名为\pi而不影响 axis中 used的原有含义。该怎么做？\sqrt{3}y\pix

案例 2

Red-Cloud 的答案适用于常量为 的第一种情况\sqrt{3}。不幸的是，如果我将其更改为1，则输出将不合理，如下所示。除了提出新问题，您能否让它对 也同样有效1？

答案1

\makeatletter
\let\pst@@VLabels\pst@@vlabels
\def\pst@@vlabels{\def\pi{\sqrt3}\pst@@VLabels}
\makeatother
\begin{document}
[...]
\end{document}

答案2

我认为没有（也就是说，我没有找到）内置方法来做到这一点。您可以修补和标签的etoolbox代码以添加任意定义：xy

\usepackage{etoolbox}
\makeatletter
\patchcmd\pst@@vlabels
  {\vbox to -\psk@ylabelOffset}
  {\YAxis@labelHook@code\vbox to -\psk@ylabelOffset}
  {}{\FailedToPatch}
\define@key[psset]{pst-plot}{ExecuteBeforeYLabels}[]{\def\YAxis@labelHook@code{#1}}
\patchcmd\pst@@hlabels
  {\ifcase\psk@xlabelPos}
  {\XAxis@labelHook@code\ifcase\psk@xlabelPos}
  {}{\FailedToPatch}
\define@key[psset]{pst-plot}{ExecuteBeforeXLabels}[]{\def\XAxis@labelHook@code{#1}}
\psset{
  ExecuteBeforeYLabels={},
  ExecuteBeforeXLabels={},
}
\makeatother

那么您只需要：

\psset{ExecuteBeforeYLabels={\def\pi{\sqrt{3}}}}
