What would you like to do?
dataframe chaining while plotting
# what I will do here:
# - dataframe chain
# - keep to pass dataframe while plotting with `StatsPlots.@df`
# - pass columns names as variables
using DataFrames, Pipe, StatsPlots
df = DataFrame(x = randn(100), y = rand(Int, 100))
v1, v2 = :x, :y
v3 = :z
@pipe df |>
transform(_, [v1, v2] => ((x,y)->(x.*y)) => v3) |>
abs.(_) |>
(@df _ plot(cols(v2); label = ^(v2)); _) |> # keep to pass dataframe while plotting
@df _ plot!(cols(v3); yscale = :log10, label = ^(v3)) # more plotting
