here is a solution with pst-3dplot

\documentclass{article}
\usepackage{pst-3dplot}
\begin{document}

\begin{pspicture}(-3,-3)(3,3)
 \psset{Alpha=30}
 \pstThreeDCoor
 \pstThreeDLine(3,3,0)(0,0,0)(-3,3,0)
 \pstThreeDEllipse[arrows=->,arrowscale=1.5,
   endAngle=90](0,0,0)(1,1,0)(-1,1,0)
\end{pspicture}

\end{document}
