I would like to plot a joint distribution as two normalized histograms. One distribution has a weight w and the other has a weight 1-w. Unfortunately, I cannot figure out how to apply the weight to a normalized histogram.
```julia
using Plots, Distributions
y = rand(Normal(0, 1), 10_000)
w = .5
histogram(y, norm=true, weights=fill(w, 10_000))
```
The density does not change with the weights. Any help would be greatly appreciated

I think the problem is that it is normed after the weights are applied. Does anyone know of a work around?

Fortunately, the data can be accessed from the plot object and modified. It was just difficult to find.
```julia
using Plots, Distributions
y = rand(Normal(0, 1), 10_000)
w = .5
p = histogram(y, norm=true)
p[1][1][:y] .*= w
display(p)
```
