Unfilled line plot for density

[rashidrafeek]

Is it possible to remove the fill color of the default density plot and just get a line plot? Using Makie it can be achieved as (See https://discourse.julialang.org/t/makie-density-line-plot/63137):

Makie.density(randn(1_000), color = (:red, 0.0), strokearound = false, strokecolor = :blue, strokewidth = 2)```

which gives,

The same attributes does not work with density in AoG:

layers = mapping(randn(1_000)) * density() * visual(; strokearound=false, strokecolor=:blue, strokewidth=2)

draw(layers)

It should work if you call the plot type within the visual, rather than using density analysis:

layers = mapping(randn(1_000)) * visual(Density; color=(:red, 0), strokearound=false, strokecolor=:blue, strokewidth=2)

alternatively, you can use the density analysis and the new subvisual feature to update the line and fill properties individually:

layers = mapping(randn(1_000)) * AOG.density() * subvisual(:line, color=:blue, linewidth=2) * subvisual(:area, visible=false)
