```Hi,

do you mean
Needs["Geometry`Rotations`"]

gg = Plot[Sin[x], {x, 0, 2Pi}];

and

With[{phi = Pi/3},
Show[
gg /. Line[pnts_] :> Line[Rotate2D[#, phi, {Pi, 0}] & /@ pnts]
]
]

or

With[{phi = Pi/3},
Show[
FullGraphics[
gg] /. {Line[pnts_] :> Line[Rotate2D[#, phi, {Pi, 0}] & /@
pnts],
Text[what_, pnt_, args__] :>
Text[what, Rotate2D[pnt, phi, {Pi, 0}], args]}
]
]

Regards
Jens
