Is it possible to have legend with
red green blue orange
05
10
15
20
with sized colored images in each cell and row/column labels?
f = Figure()
Axis(f[1, 1])
markersizes = [5, 10, 15, 20]
colors = [:red, :green, :blue, :orange]
for ms in markersizes, color in colors
scatter!(randn(5, 2), markersize = ms, color = color)
end
group_size = [MarkerElement(marker = :circle, color = :black,
strokecolor = :transparent,
markersize = ms) for ms in markersizes]
group_color = [PolyElement(color = color, strokecolor = :transparent)
for color in colors]
legend = Legend(f[2,1],
[MarkerElement(marker=:circle, markersize=size, color=color, strokecolor=:transparent)
for size in markersizes for color in colors])

I guess the answer is that that is not implemented, but you could as a workaround create
an inset plot without tick marks and labels, and put your axis labels and dots to mimic that.

You can kind of recreate some of the legend code. Make a gridlayout, put labels in it, add boxes in which you plot legend elements. The empty Attributes() is usually populated using the legend theme, but if you pass all attributes yourself you don’t need it.
using CairoMakie
f = Figure()
Axis(f[1, 1])
gl = f[1, 2] = GridLayout(tellheight = false)
for (i, label) in pairs(["a", "b", "c"])
gl[1, i+1] = Label(f, label)
end
for (i, label) in pairs(["x", "y", "z"])
gl[i+1, 1] = Label(f, label)
end
for i in 2:4, j in 2:4
b = gl[i, j] = Box(f,
color = :transparent,
width = 30,
height = 30,
strokecolor = :transparent)
MakieLayout.legendelement_plots!(
f.scene,
MarkerElement(
color = rand(RGBf0),
markersize = rand(10:20),
marker = :circle,
strokewidth = 0,
strokecolor = :black,
markerpoints = [Point2f0(0.5, 0.5)]
),
b.layoutobservables.computedbbox,
Attributes()
)
end

Thanks, that helped.
using CairoMakie
f = Figure()
Axis(f[1, 1])
markersizes = [5, 10, 15, ]
colors = [:red, :green, :blue, :orange]
for ms in markersizes, color in colors
scatter!(randn(5, 2), markersize = ms, color = color)
end
gl = f[2,1] = GridLayout(tellwidth = false)
gl[1,2:6] = Label(f, "Color",)
for (i, label) in pairs(string.(colors))
gl[2, i+2] = Label(f, label)
end
gl[2:6,1] = Label(f, "Size")
for (i, label) in pairs(string.(markersizes))
gl[i+2, 2] = Label(f, label,)
end
for (ic, c) in enumerate(colors), (im, m) in enumerate(markersizes)
b = gl[im+2, ic+2] = Box(f,
color = :transparent,
width = 30,
height = 30,
strokecolor = :transparent)
MakieLayout.legendelement_plots!(
f.scene,
MarkerElement(
color = c,
markersize = m,
marker = :circle,
strokewidth = 0,
strokecolor = :transparent,
markerpoints = [Point2f0(0.5, 0.5)]
),
b.layoutobservables.computedbbox,
Attributes()
)
