[pstricks] Using ps code in psplot's limits

[Juergen Gilg]

Dear Hubert,

of course you can directly insert PS for x_min/max, like

\documentclass{article}
\usepackage{pstricks-add}
\begin{document}
\begin{pspicture}(-1.5,-0.5)(4.5,5.5)
\psplot[algebraic=true,plotpoints=100]{0}{Pi 4 div}{sin(x)}
\psaxes{->}(0,0)(-0.5,-1.5)(5.5,1.5)
\end{pspicture}
\end{document}

Regards,

Juergen
