Export to PS Tricks TEX macro

[oparch t-online de (M. Opris)]

I have two questions:

 

1. I've drawn with Dia a graph. Then I've exported it to PS Tricks TEX macro and I've compiled it.

And then it has come out the next error massage:

 

! undefined control sequence

l.20 \ pspicture

   (1.8,-10)

   (39.74,-2.10)

 

I've tried zu change the coordinate in the TEX-file, but the error massage came again.

How can I repare it?

 

2. How can I view the graph?
