try it :-)


or look at the documentation 

\begin{pspicture}(x0 ,y0 )(x1, y1)
    picture objects

The picture objects are put in a box whose lower left-hand corner is at
(x0 , y0 ) (by default, (0,0)) and whose upper right-hand corner is at 
(x1, y1).

Then it is best to give the pspicture the size of the contained objects 
and put it in an appropriate box (for example 'center' environment):


(the \fbox is only to visualize the size of the pspicture-environment)
