It is open-source software, not a walled garden - there are going to be multiple options, and they are not going to all be named ["PLOTTINGISHERE$i" for i in 1:4].
If you like MATLAB/pyplot/matplotlib style, PyPlot.jl is for you.
If you like ggplot2, Gadfly.jl is for you.
If you like gnuplot, Gaston.jl is for you.
Finally, but not least, is Winston.jl, which is its own thing altogether.
I think in many cases its good for packages that overlap to come together/one to become dominant, but I don't think that applies here.
