Hi,

I tried to use Makie DataInspector for logscale graph and it is not workin,

MWE:

```julia
fig = Figure()

Axis(fig[1,1], xscale = log10)

lines!(range(0.01, 0.99, length = 200), 1:200)

DataInspector(fig)

```

ERROR:

> Error in callback:  
> DomainError with -0.010894682:  
> log10 was called with a negative real argument but will only return a complex result if called with a complex argument. Try log10(Complex(x)).

It seems that it is already there [DataInspector does not work for lines in log10 scale · Issue #3571 · MakieOrg/Makie.jl · GitHub](https://github.com/MakieOrg/Makie.jl/issues/3571)
