Is anyone versed in wxMaxima?

I need to do a parametric plot of equations Y(t) and X(t) in wxMaxima.

The help manual says the command for this is:

parametric(X(t),Y(t),t,paramin,paramax)$

I do exactly this and nothing happens.

Any idea what's goin on?

If you're not versed in wxMaxima but know how to do parametric plotting in Mathematica or Maple, then I would appreciate that advice too.

Thanks
