using Winston, KernelDensity
 
k = kde(rand(100))

k1 = k.x[k.x .< .5];

k2 = k.x[k.x .> .5];

f1 = FillBelow(k1, k.density[1:length(k1)], color="blue");

f2 = FillBelow(k2, k.density[length(k1)+1:end], color="red");

p = FramedPlot()

add(p, f1, f2)

To answer question #1 only, this works ...

using Winston, KernelDensity

k = kde(rand(100))

fieldnames(k)

# outputs ...

# 2-element Array{Symbol,1}:
# :x  
# :density

f = FillBelow(k.x, k.density, color="blue")
p = FramedPlot()
add(p,f)















So now the only question is how to split this into two colors.

I'll be honest, the code to do this in R is substantially more 
non-intuitive. Nice work Mike!
