Hi,
gr = FullGraphics[
Plot[Sin[x], {x, 0, 2Pi},
Frame->True,
FrameTicks -> {Table[xi, {xi, 0, 2Pi, Pi/4}], Automatic}, (* set
the ticks *)
Epilog -> {AbsoluteThickness[2], Line[{{Pi, -1}, {Pi, 1}}]} (*
draw the vertical line *)
]
]
and add the second background color for x>Pi
Show[gr, Prolog -> {GrayLevel[0.9], Rectangle[{Pi, -1}, {2Pi, 1}],
GrayLevel[0]}]
Regards
Jens
