  Weird.  I think you need to give us a reproducible example
so we can help.  The best thing, if possible, would be to 
give us an example of the code you used and simultaneously
to post examples of the output to a web page somewhere, if
that's possible.

  I would just say, e.g.,

curve(x^3-2*x^2+x-1,from=-10,to=10)

 there is an "n=" argument that specifies how many points
to use, but it doesn't seem necessary.
