1.) Using the "school" syntax you need to add "algebraic=true" or you have to use the RPN (reverse polish notation) of PostScript-Language.<br>
2.) You are going to encounter a "bad" drawstyle, even using plotstyle=curve (since the edges get overdrawn in circular shape), best results (so far): use plotpoints=1000. Surely this needs to be adjusted in case that the image is resized to extremly large (or small) size.<br>
3.) The size of that pspicture is not matching the paperformat, though the image is placed acceptable centered on that page. You might want to add a \noindent\resizebox{\linewidth}{!}{...<content>..}<br>
4.) Since you are not sure about parskip/parindent it's always nice to place \noindent in front of that pspicture environment.<br>
