VegaLite: facet plot with running average layer

I have a dataset with continuous values and would like to plot those values together with their running averages in a layered plot. Works well in this simple case: using Random, DataFrames, Queryverse Random.seed!(1234) df = DataFrame(index=1:100, value=rand(100)) df |> @vlplot(transform=[{frame= [-15, 15], window=[{op=:mean, field=:value, as=:avg_value}]}]) + @vlplot( mark={:line, strokeWidth=2, opacity=0.5}, x="index:q", y="value:q" ) + @vlplot( mark={:line, strokeWidth=3}, …

The solution wasn’t obvious so maybe it is similar here. Could you try for yourself? I could perhaps look later into details.
