My kerneldensity.jl

using JLD2, KernelDensityEstimate, KernelDensityEstimatePlotting
@load "seasontop.jld2" spri_tops
p = kde!(convert(Vector{Float64},spri_tops))
plot(p)

spri_tops is a 1-d Array of Float32, so I convert it to Float64.

Is it too bit?

Hi, apologies I did not see the latest two issues here. Yes Fontconfig and Cairo warnings are to do with changes in Gadfly.jl (with KernelDensityEstimatePlotting.jl as user). At time of writing I think the best thing to do is:

using Cairo, KernelDensityEstimatePlotting

which should suppress the warning. There has been quite a bit of work by the Gadfly folks to move away from system font libraries, and this warning might be part of that migration.
