Hello!
I am drawing an arrows plot in GLMakie,
Where can I find a list of the legal inputs to the arrowhead keyword?

Hi. Generally for the 2D case that can be any character:
```julia
julia> arrows(xs, ys, us, vs, arrowsize = 10, lengthscale = 0.3,
arrowcolor = strength, linecolor = strength, arrowhead='H')
```
But, probably you are referring to a marker list as you can find here [Page Redirection](https://docs.makie.org/stable/examples/plotting_functions/scatter/index.html#default_markers)
```julia
# eg
julia> arrows(xs, ys, us, vs, arrowsize = 10, lengthscale = 0.3,
arrowcolor = strength, linecolor = strength, arrowhead=:rect)
```
### Disclaimer
Also `GLMakie` is just the backend used to print your visualization. The core functionality you are asking about is defined generally for `Makie.jl` and holds for all backends (e.g.`CairoMakie`, WGLMakie`, …)

Thank you for the quick reply!
I thought arrow heads would have their own markers…
How then would I make a standard arrow like this: ----\>
?

Not setting the `arrowhead` will draw a standard arrow like the example here [arrows · Makie](https://docs.makie.org/stable/examples/plotting_functions/arrows/#examples)
Or using `arrowhead='↑'` like [here](https://docs.makie.org/stable/examples/plotting_functions/scatter/index.html#marker_rotation)

You can use whatever you want, arrowheads are reasonably easy to make yourself if you want a specific one:
```julia
julia> begin
f = Figure(resolution = (800, 800))
Axis(f[1, 1], backgroundcolor = "black")
xs = LinRange(0, 2pi, 20)
ys = LinRange(0, 3pi, 20)
us = [sin(x) * cos(y) for x in xs, y in ys]
vs = [-cos(x) * sin(y) for x in xs, y in ys]
strength = vec(sqrt.(us .^ 2 .+ vs .^ 2))
arrowpoly = Makie.Polygon(Point2f[(0, 1), (0.5, -0.3), (0, 0), (-0.5, -0.3)])
arrows!(xs, ys, us, vs, arrowsize = 10, lengthscale = 0.3,
arrowcolor = strength, linecolor = strength, arrowhead = arrowpoly)
f
end
```
