I was reading about levels for DataFrames. How exactly can they be useful with Vegalite.jl?
I read about for example display purposes: when I tried to plot some data with this in mind (already some months ago), there was no automatic ordering in the plot. Maybe I was an ignorant fool about it. If so, please explain.
For example, I want to make a barplot with counts/frequency, and some variable/column has three unique values. Regardless of the counts, I want a certain value first (e.g. at the top on Y), another second, and the last third.
I supposed that Vegalite.jl (and any other plotting pack) would then recognize the order set, and plot accordingly. Am I wrong?
