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?
