The docs explain how to write “type recipes”. Can you please provide a MWE with a completely new type? As you can see below, just following the instructions in the docs leads to errors:
import Makie
# custom type
struct Foo end
# type recipe definitions
Makie.plottype(::Foo) = Makie.Scatter
Makie.convert_arguments(::Foo) = (rand(100),)
# test plot
import GLMakie as Mke
Mke.plot(Foo()) # error
ERROR: `Makie.convert_arguments` for the plot type MakieCore.Scatter{Tuple{Foo}} and its conversion trait MakieCore.PointBased() was unsuccessful.
The signature that could not be converted was:
::Foo
Makie needs to convert all plot input arguments to types that can be consumed by the backends (typically Arrays with Float32 elements).
You can define a method for `Makie.convert_arguments` (a type recipe) for these types or their supertypes to make this set of arguments convertible (See http://docs.makie.org/stable/documentation/recipes/index.html).
Alternatively, you can define `Makie.convert_single_argument` for single arguments which have types that are unknown to Makie but which can be converted to known types and fed back to the conversion pipeline.

Notice that I can already define what the documentation calls “full recipes”, but I am now interested in simple “type recipes” to forward types to existing recipes.
