Is there anyway to fill the bar in groupedbar (statsplots Julia) with something like hatch or groupfill?
That would be really useful for publications in black and white.
I tried the below without luck
J, L = 8, 3 ; beta0 = rand(L,J) ; ctg = repeat(["C","I","M"], inner = J) ; nam = repeat(string.(1:J), outer = L) ; filx = repeat([:+,:/,:x], inner = J) ; groupedbar(nam,beta0, group = ctg, xlabel = "O", ylabel = "S", legend = :topleft, fillstyle =filx, color = [:green :blue :red]) ;
