Export to TEX

["Anca-Eugenia Oprisch" <anca oprisch uni-dortmund de>]

I have two questions:

1.I've drawn with Dia a graph. Then I've exported 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
   (1.80000,-10.961345)
   (39.74070,-2.10)
  #coordinate
How can I repare it?

2. How can I view the graph?
