Funny thing I did just that a week ago. I hope this snippet helps you out.

Needed are the packages pstricks-add and pst-plot.

        \begin{pspicture}(8.5cm, 3.5cm)
                \psset{xunit=10mm, yunit=60mm}
                \psplot[linecolor=gray, plotstyle=curve]{1}{7}{x 4 1 GAUSS}
                \pscustom[linecolor=gray, plotstyle=curve, fillstyle=hlines, 
hatchcolor=gray]{
                        \psline(5.4,0)(5.4,0)
                        \psplot[liftpen=1]{5.4}{7}{x 4 1 GAUSS}
                }
                \psaxes[labels=none, ticks=x, ticksize=-1mm]{->}(4,0)(0,0)
(8,.5)
                \uput[0]{0}(8,0){$t$}
                \uput[180]{0}(4,.5){$\frac{1}{\sqrt{2\pi}} 
\mathrm{e}^{-\frac{t^2}{2}}$}
                \uput[270]{0}(5.4,0){$x$}
                \uput[270]{0}(4,0){$0$}
                \uput[270]{0}(5,0){$1$}
                \uput[270]{0}(3,0){$-1$}
        \end{pspicture}
