We had a similar question here

> [@VegaLite: facet plot with running average layer](https://discourse.julialang.org/t/vegalite-facet-plot-with-running-average-layer/35463):
>
> 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.
