Hello everyone,  
I have 2d vectors u and v which are velocity fields in x and y direction, How can I plot the streamlines?

> For @tyfdzt: here are the basic components extracted from my code with Makie streamplots. Note that it is not a MWE. I hope it can help you. If not I can try to write a MWE. #The Cartesian axis : x = range(0,stop=lx,length=nx+1); hx = lx/nx; y = range(0,stop=ly,length=ny+1); hy = ly/ny; #Arrays for x and y velocity arrays that evolve via CFD simulation Ue=zeros(nx+2,ny+2) Ve=zeros(nx+2,ny+2) ..... #Declare a Makie Node (once) for storing velocity arrays uvn=Node([rand(size(Ue)...),rand(size(Ve…

Yes, I submitted an [issue here](https://github.com/JuliaPlots/Makie.jl/issues/606).
