hidedecorations! functionality not working

[grolicus]

Absolute newbie here.
The hidedecorations! function doesn't function properly in the code below, probably due to an oversight on my part, because the function does hide just the label on the (0,0) point. The goal however is to hide all axes, ticks, labels,etc., and to draw only the red quarter of the squircle function.
I then copied two lines from the Makie manual on hidedecorations to specify axes in particular, which only hid the title I added, but no other decorations.

Code:
`using CairoMakie
Makie.inline!(true)

arrLeftDown = []
for x in -1:0.01:0
y=-((1-(x^4))^(1/4)) # based on squircle formula x^4 + y^4 = 1
push!(arrLeftDown, (x,y))
end

fig = Figure(size = (800, 800))
lines(fig[1, 1], arrLeftDown, color = (255,0,0))
ax = Axis(fig[1, 1], title = "Axis 1")
hidedecorations!(ax)
fig`

Probably just a noob oversight, but any light on the subject much appreciated.

Hey, welcome to Makie!

lines(fig[1, 1], arrLeftDown, color = (255,0,0))
ax = Axis(fig[1, 1], title = "Axis 1")

This is creating two axes - one is implicitly created from the lines plot, and the other is created explicitly by calling Axis. You have two options to solve this:

• Create the axis explicitly, as in

ax = Axis(fig[1, 1]; title = "Axis 1")
lp = lines!(ax, arrLeftDown; color = RGBf(1,0,0))

• Use the implicitly created axis and do not create another axis

ax, lp = lines(fig[1, 1], arrLeftDown, color = RGBf(1,0,0))

Then hidedecorations! will only have a single axis to work on. What's happening now is that you're hiding the explicitly created axis, but not the one which is created by lines.
