Yes, this has aggravated me for quite some time, but I haven't been
able to figure out how to get it to not do this, since Sage doesn't
analyze the algebraic structure of things it plots, nor (probably?)
should it. See http://trac.sagemath.org/sage_trac/ticket/3985

Try maxima.plot2d and maxima.plot2d? ; I can't get that to work either
but that may be something broken in my installation of Maxima, which
has been acting up since I upgraded. Otherwise ask back and someone
will help you.
