Hello,
Although Mathematica does not explicitly support transparency, I think
you could obtain such plots with a bit of work.
Consider something like this:
s = ImportString[ExportString[Plot[Sin[x], {x, 0, 10}, DisplayFunction
-> Identity], "GIF"], "GIF", ConversionOptions -> {"ColormapOutput" ->
False}]
This will create a simple plot in the form of a raster of rgb values
(look at it in InputForm to see its exact structure). Given two of
those, it would not be hard to blend them together to create some sort
of transparent effect - just make sure you use PlotRange to force them
on to the same scale.
