Even better, use:
  plot2d(...,[legend,false])
it works both in gnuplot and openmath (it is documented in the manual).

Take a look at these two graphs:

(%i1) f(x):=4*x*(1-x)$
(%i2) x:0.745$
(%i3) for i thru 400 do x:f(x)$
(%i4) x;
(%o4)     0.99522128492706
(%i5) load(dynamics)$
(%i6) staircase(f('x),x,80)$
(%i7) x;
(%o7)     0.99522128492706
(%i8) evolution(f('x),x,80)$

You don't need Xmaxima. Either gnuplot or openmath will work.
