hello,
I would like to use \parabola to draw a parabola that passes through
(-1,0) with a maximum at (1,3).
It is possible to draw this parabola for x greater than 1 ? lower
than -1 ?
Should I use \psplot instead ?
Here is my code :
\documentclass{minimal}
\usepackage{pst-plot}
\begin{document}
\begin{pspicture*}(-3,-3)(5,5)
% \psgrid
\psaxes(0,0)(-2,-2)(4,4)
\parabola(-1,0)(1,3)
\end{pspicture*}
\end{document}
Thanks,
mokaude
