How to add axis labels and change marker shape for each group

[itsdfish]

Hello,

Thank you for putting together this package. I would like to plot a 3-simplex in a ternary diagram where the fourth dimension represented by a color gradient. I encountered problems adding axis labels and representing two groups of data with different marker shapes. I was wondering if you might provide some guidance. Here is a MWE:

using Makie 
using GLMakie 
using TernaryDiagrams
using Distributions
using ColorSchemes 

fig = Figure();
ax = Axis(fig[1, 1]);

ternaryaxis!(ax; labelx = "1", labely = "2", labelz = "3");

data1 = rand(Dirichlet([5,1,1,10]), 10)'
data2 = rand(Dirichlet([1,5,1,1]), 10)'
ternaryscatter!(
    ax,
    data1[:,1],
    data1[:,2],
    data1[:,3],
    color = [get(ColorSchemes.Spectral, w, extrema(data1[:,4])) for w in data1[:,4]],
    marker = :circle,
    markersize = 20
)

ternaryscatter!(
    ax,
    data2[:,1],
    data2[:,2],
    data2[:,3],
    color = [get(ColorSchemes.Spectral, w, extrema(data2[:,4])) for w in data2[:,4]],
    marker = :triangle,
    markersize = 20
)
fig

Thank you in advance.

What was the issue? The below code seems to produce a sensible image (slight adaptations from your code):

using GLMakie 
using TernaryDiagrams
using Distributions
using ColorSchemes 

fig = Figure();
ax = Axis(fig[1, 1]);

ternaryaxis!(ax; labelx = "1", labely = "2", labelz = "3");

data1 = rand(Dirichlet([5,1,1,10]), 10)'
data2 = rand(Dirichlet([1,5,1,1]), 10)'
ternaryscatter!(
    ax,
    data1[:,1],
    data1[:,2],
    data1[:,3],
    color = [get(ColorSchemes.Reds, w, extrema(data1[:,4])) for w in data1[:,4]],
    marker = :circle,
    markersize = 20
)

ternaryscatter!(
    ax,
    data2[:,1],
    data2[:,2],
    data2[:,3],
    color = [get(ColorSchemes.Blues, w, extrema(data2[:,4])) for w in data2[:,4]],
    marker = :utriangle,
    markersize = 20
)

xlims!(ax, -0.2, 1.2) # to center the triangle and allow space for the labels
ylims!(ax, -0.3, 1.1)
hidedecorations!(ax) # to hide the axis decorations

Great. Thank you for your help!
