Plotting mixture of measurements and missing data

[chriswaudby]

Hi,

I've got some results that are a mixture of measurements and missing data (type Vector{Union{Missing, Measurement{Float64}}}). However, I get a MethodError if I try to plot these:

plot([1±.1, 2±.3, missing, 4±.05])

MethodError: no method matching Float64(::Measurements.Measurement{Float64})
Closest candidates are:
(::Type{T})(::Real, !Matched::RoundingMode) where T<:AbstractFloat
@ Base rounding.jl:207
(::Type{T})(::T) where T<:Number
@ Core boot.jl:792
(::Type{T})(!Matched::AbstractChar) where T<:Union{AbstractChar, Number}
@ Base char.jl:50
...

_plot!(::Plots.Plot, ::Any, ::Any)@plot.jl:223

Not sure if this is best raised here or with Plots!

Best,

I presume the fix should be done here because the recipes live in this repository, but I'm not sure what the solution should be, I'm not familiar with how Plots deal with missing data. Is it only a matter of adding methods for Vector{Union{Missing, Measurement}} and sprinkle skipmissing around?
