[pstricks] Rotate and center a figure

[jmpapy]

If you rotate the whole pspicture environement it's better.
Try this code.

\documentclass{article}
\usepackage{amsmath,amsfonts,amssymb}
\usepackage{pstricks,pstricks-add}
\begin{document}
\vspace*{8cm} 
\begin{center}
\psset{xunit=6.4cm,yunit=5.5cm}
\rput{90}{
\begin{pspicture}[0.5](0,0)(3,1.5)
\psframe(0,0)(3,1.5)
\psline[linewidth=1.5pt]{->}(0,0)(3,0)
   \psline[linewidth=1.5pt]{->}(0,0)(0,1.5)
   \psline[linewidth=1.5pt](0,1)(3,1)
   \uput[d](2.9,0){$x$}
   \uput[l](0,1.4){$y$}
   \uput[l](0,1){$1$}
   \uput[u](0.4,1){$\Delta$}
   \uput[dl](0,0){O}
   \uput[d](1,0){$1$}
   \psplot{0}{3}{1  x 2 exp 2.71828 1 x 2 exp sub exp mul sub}
   \uput[d](2.8,0.96){$\mathcal{C}$}
  \end{pspicture}}
\end{center}
   \end{document}
