Dear MathGroupers,

Is it possible to have a background colour for a plot that only affects the

area inside the frame? The normal Background option also colours the area

under the frame and axes numbers in the background colour, which is not what

I want. I can fake the effect by drawing a rectangle with the same

dimensions as the PlotRange (see example code below), but then white

gridlines on a grey background are impossible.

For reference, the kinds of graph styles I am trying to replicate are the

two (slightly different) styles shown in the following links. I would thus

also be grateful for suggestions on how to manipulate the tick length, and

how to get different left and right vertical scales on the same plot.

BISLineGraph[data : {{__Real} ..}, {rangemin_, rangemax_}, opts___Rule] /;

With[{numseries = Length[data], numpoints = Dimensions[data][],

datamax = Max[Join @@ data], datamin = Min[Join @@ data]},

Show[{ListLinePlot[data, Frame -> True,  PlotRange -> {rangemin, rangemax},

AbsoluteThickness}], {i, numseries}],

FrameTicks -> {Automatic, Automatic, None, Automatic},

GridLinesStyle -> Directive[GrayLevel[0.9], AbsoluteThickness],

GridLines -> {None, Automatic},

FrameStyle -> Directive[FontFamily -> "Arial", FontSize -> 11] ,

opts], Graphics[{GrayLevel[0.2], Opacity[0.1],  Rectangle[{-0.5, rangemin},

Where BISLineColours is a list of RGBColor directives.
