Edges doesn't look nice now

[diegozea]

using PlotRecipes
using Plots

const n = 15
const A = Float64[ rand() < 0.5 ? 0 : rand() for i=1:n, j=1:n]
for i=1:n
   A[i, 1:i-1] = A[1:i-1, i]
end

plot(graphplot(A, line = (3, 0.5, :blues)), graphplot(A, line = (3, 0.5, :blue)), size=(600,300))

Maybe this change is related to: https://github.com/JuliaPlots/Plots.jl/pull/1467

@diegozea do you still think that this is a problem? If so, it would be nice to have some concrete targets that need to be met in order to close this.

It looks like there is now a problem with that way of defining line colours:

julia> graphplot(A, line = (3, 0.5, :blues))

I will put it on my todo list. Besides the error, do you think that the aesthetics of edges are OK?
