Generally, I'd agree. I think I could make a strong case, though,
that alpha blending is an exception and should _never_ be applied to
the legend. The legend should display the color I've chosen, not 1/20
(or whatever) of the color I've chosen. I can't imagine a situation
where I'd actually want very dim, faintly colored items in my legend.
Additionally, you'll notice in the example code I gave, the alpha
blending is applied even to the size scale, which has nothing to do
with the colors scale being used. Why dim every single symbol in the
legend? That just makes no sense to me, but I'm certainly open to
I suppose one option would be to actually add an entirely new legend
scale every time you use alpha blending that shows the depth of color
changes as items are overplotted, and this would be separate from any
color scale, which would be displayed with the "true" colors.
But in any case, at least I think your answer confirms that there is
no (easy) way to do what I want, at least at the moment...
