There was some discussion about a rotated inset axis recently, might be interesting for you:

> I’m interested in understanding how one can rotate a whole axis/plot in Makie, in order to produce visualizations like the one below. This solution was posted by Simon Danisch on Slack: using GLMakie f, ax, pl = barplot(rand(5), bar\_labels=:y, figure=(resolution=(500, 500),)) hideydecorations!(ax) hidespines!(ax, :t, :r, :l) hidexdecorations!(ax, ticks=false) tightlimits!(ax) f img = Makie.colorbuffer(ax.scene) f, ax, pl = scatter(rand(Point2f, 100), axis=(aspect = DataAspect(),)) …

> Unfortunately, this does not work on CairoMakie. As pointed out by @ffreyer who posted this solution: "This works for me in GLMakie but CairoMakie still has two problems - text gets transformed differently and disappears, and the background pane of the rotated axis doesn’t draw over the normal axis. I think these are things that need to fixed in CairoMakie though."

If `text!` doesn’t work correctly with `rotate!` (which I don’t think it does) you should still be able to do things manually. If you rotate the whole scene (i.e. ax.scene or f.scene.children[1]) you can get the pixel position within that scene for a data position with `px_pos = project(ax.scene, position)`. You can use that to plot text at the correct position by plotting to `f.scene`, which is in pixel units. You need to add the offset from `ax.scene` though, so it becomes

```julia
positions = Point2f[(1, 1), (2, 1), (3, 1)]

fig, ax, p = scatter(positions, color = [:red, :green, :blue])
rotate!(ax.scene, Vec3f(0,0,1), pi/4)
xlims!(ax, -0.5, 2.0)
ylims!(ax, 1, 3)

px_positions = map(positions) do pos
    Makie.project(ax.scene, pos) + minimum(ax.scene.px_area[])
end
text!(
    fig.scene, ["First", "Second", "Third"], position = px_positions, 
    color = [:red, :green, :blue], rotation = [0.0, pi/4, -pi/4]
)

fig

```

or

```julia
px_positions = map(ax.scene.camera.projectionview, ax.scene.px_area) do _, px_area
    map(positions) do pos
        Makie.project(ax.scene, pos) + minimum(px_area)
    end
end

```

to make the text positions update automatically.
