Details

Plotting an empty scatter plot (scatter([],[])) works in 2D in GR.
scatter2D

It, however, fails in 3D (scatter([],[],[])) with a very cryptic error message:

BoundsError: attempt to access 0-element Vector{Tuple{Float64, Float64, Float64}} at index [1]

I cannot reproduce on 1.6.5 nor 1.7.2.
You are using Julia Version 1.7.0-rc1 which by definition (rc) is unsupported. Please update your julia version, and come back with a working mwe ?

I can reproduce this on 1.7.2, i also get a warning about an unsupported keyword argument letter which shouldn't appear

Can you post your backtrace as well ?
I see svg+xml references, so there must be some save commands involved.

Ok thanks, sorry for the noise, I had a --check-bounds=no in my julia launcher.

It looks like github CI / actions are hanging so this might take a while to get the new version in registry for updating:
JuliaRegistries/General#57159.
