Dear folks - I am trying to plot a sine wave with the middle portion grayed out. The Plot command seems like the way to go, but I can't figure out how to get my rectangle to come out in like a GrayLevel[0.5]. (See syntax below) Is it possible to adjust the shade of gray on the rectangle? I'm working off the example on page 413 of the mathematica book. If it is not possible to adjust the shade used with this command, can you suggest an alternate way? Plot[Sin[x]*50, {x, 0, 2Pi}, Prolog -> Rectangle[Scaled[{0.02, 0.25} ] , Scaled[{1, 0.75}] ]] Thanks in advance, JP
