Tweaking a plot

[greimel]

I am posting examples of how to tweak a plot for future reference. When I find time I will set up a docs PR including what I posted in #40 and #42 (unless a more convenient way to achieve theses things is implemented).

Simple baseline plot

using AbstractPlotting, CairoMakie, MakieLayout, AlgebraOfGraphics

N = 500
x = rand(N)
df = DataFrame(x = x, y = x .+ randn(N))

cols = style(:x, :y)
scat = spec(Scatter)
pipeline = cols * scat
aog_simple = data(df) * pipeline

aog_simple |> draw

scene, layout = MakieLayout.layoutscene()

AlgebraOfGraphics.layoutplot!(scene, layout, aog_simple)

Adjusting color and transparency

grd_lay = layout.content[1].content # get the `GridLayout`
lax = grd_lay.content[1].content # get the `LAxis`
lax.scene.plots[1].color[] = (:red, 0.5)

It might be useful to explicitly show how you get the LAxis in docs - from there, any manipulation becomes easy to do.

I edited the code to make to make this more explicit.

I also just found out that one can do spec(Scatter, alpha=0.2), which is nice.

also for future reference, instead of

grd_lay = layout.content[1].content # get the `GridLayout`
lax = grd_lay.content[1].content # get the `LAxis`

you can now do

grd_lay = contents(layout)[1]
lax = contents(grd_lay)[1]
