Request: Log-scales should use original units

[ParadaCarleton]

AoG offers log scales, but they seem to behave awkwardly. Asking for log scales on a density currently results in replacing

However, I don't think this is a very commonly-used operation--usually, plotting the uncorrected density is probably a mistake.

Instead, usually what I want is to have log(x) with tick-marks labeled in the original units. Instead of seeing 1, 2, 3... I'd prefer $10, $100, $1000... along the x-axis, to help me interpret the graph in units I understand.

I don't get what the issue is, an MWE would be good

I had a look today and I realise I also don't understand the original question (sorry jkrumbiegel 😅).

Taking the example from the FAQ docs,

log-e x-scale:

julia> using CairoMakie, AlgebraOfGraphics

julia> using AlgebraOfGraphics: density

julia> df = (x = exp.(randn(1000)),)
(x = [0.2902271880952832, 0.7266166553765828, 1.2224270032596198, 1.1556703385577687, 1.039192132661528, 0.5057566035686333, 1.9256338664589439, 0.6326547724870978, 1.4070911916039912, 0.4846729493884399  …  1.2340141235965212, 1.4771395600162527, 1.6945694302578178, 1.4368012315220762, 2.132316760616112, 0.6859097611065411, 0.2833281990510391, 2.430832649126153, 0.5593374132456983, 0.16772035493995438],)

julia> kde1 = data(df) * mapping(:x) * density()
Layer
  transformation: AlgebraOfGraphics.DensityAnalysis{MakieCore.Automatic, MakieCore.Automatic, MakieCore.Automatic}(MakieCore.Automatic(), 200, MakieCore.Automatic(), MakieCore.Automatic())
  data: AlgebraOfGraphics.Columns{@NamedTuple{x::Vector{Float64}}}
  positional:
    1: x
  named:


julia> draw(kde1, axis=(width=225, height=225, xscale=log,))

linear x-scale:

draw(kde1, axis=(width=225, height=225))

log-10 x-scale:

draw(kde1, axis=(width=225, height=225, xscale=log10,))

In all cases, the x-tick labels are the same "units" as the original data.

@ParadaCarleton what exactly is your problem? As jkrumbiegel said, we'll need a MWE from you. Were you using Unitful.jl?
