is there a way to fill the area under the curves with dashed lines (left to right for one curve and right to left for the other) with a transparent filling between lines? I cannot even get dashing under the curve.
Show[{Plot[Sin[x], {x, 0, 2*Pi}, PlotStyle -> Blue, Filling -> Axis],
Plot[Cos[x], {x, 1, 2 Pi}, PlotStyle -> Green, Filling -> Axis,
FillingStyle -> Opacity[0.2]]}]
