After reading an arrow file I get the following type:
julia> sl.heading
200-element Arrow.Primitive{Float32, Vector{Float32}}:
-0.0023596277
-0.004771689
-0.0052604624
ā®
-0.31095406
-0.33066812
-0.338615
If I want to plot it using PyPlot I need to apply collect, which is bad because it allocates.
Is there a way to convert this into a type that PyPlot.jl can handle without copying?
