Constraints

  • I only want to use \psaxes rather than multiple calls of \psxTick, \rput, \uput.
  • I want to have trigonometric labels with even multiple of π/3.

My attempts

As usual, we can have trigonometric labels of multiple of π/3 without any problem.

\begin{pspicture}(-\psPiTwo,-1)(\psPiTwo,1) 
    \psaxes[dx=\PiOverThree](0,0)(-\psPiTwo,-1)(\psPiTwo,1)
\end{pspicture}

In order to get even multiple of π/3, I changed dx=\TwoPiOverThree as follows.

\begin{pspicture}(-\psPiTwo,-1)(\psPiTwo,1) 
    \psaxes[dx=\TwoPiOverThree](0,0)(-\psPiTwo,-1)(\psPiTwo,1)
\end{pspicture}

However, this change should be followed by setting Dx=\TwoPiOverThree. Unfortunately, setting Dx produces errors (that you can see by compiling my MWE below).

Minimal Working Example

\documentclass[preview,border=12pt,12pt,dvipsnames]{standalone}
\usepackage{pst-plot}

\def\PiOverThree{1.047197}
\def\TwoPiOverThree{2.094395}

\psset
{   
    xtrigLabels,
    trigLabelBase=3,
    xunit=\PiOverThree,
}


\begin{document}
\section*{With $\pi/3$ step (completed)}

\begin{pspicture}(-\psPiTwo,-1)(\psPiTwo,1) 
    \psaxes[dx=\PiOverThree](0,0)(-\psPiTwo,-1)(\psPiTwo,1)
\end{pspicture}

\section*{With $2\pi/3$ step (uncompleted)}

\begin{pspicture}(-\psPiTwo,-1)(\psPiTwo,1) 
    \psaxes[dx=\TwoPiOverThree](0,0)(-\psPiTwo,-1)(\psPiTwo,1)
\end{pspicture}


% does not compile
%\begin{pspicture}(-\psPiTwo,-1)(\psPiTwo,1)    
    %\psaxes[dx=\TwoPiOverThree,Dx=\TwoPiOverThree](0,0)(-\psPiTwo,-1)(\psPiTwo,1)
%\end{pspicture}
\end{document}

Bonus Questions

How to set different trigLabelBase for x-axis and y-axis? I cannot find xtrigLabelBase and ytrigLabelBase in the pst-plot documentation. They might not be implemented yet.
