Update xlims in interactive GLMakie

I have the question how to make xlims and ylims update automatically when an Observable changes.
For instance:

x=1:10 |> collect |> Observable
fig, ax, plt = scatter(x, @lift($x .^ 2))
fig

Updating x does not lead to updating the xlims and ylims, unless I call autolimits!(ax)

I tried also

on(x) do i
     autolimits!(ax)
end

but this caused
ERROR: MethodError: no method matching (::var"#183#184")(::Vector{Int64})

Thanks!

EDIT:
Ok, it seemed there was another wrong on(x) defined…
This works

z=1:10 |> collect |> Observable
fig, ax, plt = scatter(z, @lift($z .^ 2));
on(z) do i
     autolimits!(ax)
end
fig

Still, is this “correct”?

Yes, that’s the way to go.

A maybe short follow up question. Am I right, that this does (still?) not work with AlgebraofGraphics?

I have tried to @lift at various levels without success. Outside everything for instance I get:

plt =  @lift(data(df) * ... ) # Code not shown
julia> draw(plt)
ERROR: MethodError: no method matching draw(::Observable{Layers})

Thanks!

Sorry, continued to try…
This seems to work:
@lift(display($plt))
Are there any guides/rules at which level the @lift should be applied. E.g. in the post above it can be inside scatter.

So in general you can lift almost any parameter passed into specific plot functions in GLMakie.
However, draw() is a function specific to Algebra of Graphics and it does not seem to have this implemented.

You should in general lift those things you want to change after you plotted the figure, e.g. data points or colors.
Can you interactively change anything in the plt from your last post? Cause my guess would be that it would not work, but I also have no experience with AoG.

Thanks - I created a new topic with a MWE…: Interactive Menu with AlgebraOfGraphics / GLMakie
