To turn off the "side effect" of display of a graphics object, use option DisplayFunction -> Identity: g = Plot[x^2, {x, -1, 1}, DisplayFunction -> Identity]; To turn display back on later for an already-created graphics object: Show[g, DisplayFunction -> $DisplayFunction]; WGM wrote: > > Hi, my request is going to seem sort of silly, so I'll explain what > I'm trying to do.
