Write a function that builds a list of the plots you want to draw (with
DisplayFunction->Identity to suppress their premature display) ---
depending on parameters you pass to that function --- and Show the
resulting list of plots with DisplayFunction->$DisplayFunction.

Hi, my request is going to seem sort of silly, so I'll explain what
I'm trying to do.  I'm creating some fairly complex plots in
mathematica that are made of curves produced by ParametricPlot[] and
other graphics produced from Graphics[] commands.  My problem is that
I want to be able to easily turn certain plots "off" and "on."  I'd
like to do this with PlotStyle if possible, but all the obvious things
don't work.  For instance, if you do

Plot[x^2,{x,-1,1},PlotStyle->Thickness[0]]

you can still see the graph.  I've also tried AbsoluteThickness[0],
PointSize[0], AbsolutePointSize[0], and Dashing[{}] and none of them
make the plot disappear.  I can't set the color to white, because then
the curves I'm trying to hide appear to erase the other curves in my
picture.

Does anyone know an option I can give to ParametricPlot that will
cause it to not draw a graph?
