Hi there!
I was wondering how to put labels on a pie chart in Makie. Like in the example shown on the page.
using CairoMakie
data = [36, 12, 68, 5, 42, 27]
colors = [:yellow, :orange, :red, :blue, :purple, :green]
f, ax, plt = pie(data,
color = colors,
radius = 4,
inner_radius = 2,
strokecolor = :white,
strokewidth = 5,
axis = (autolimitaspect = 1, )
)
f
How could I for example use to colors as a label, all the things I tried did not work out…
Thanks!
what about doing:
using GLMakie
data = [36, 12, 68, 5, 42, 27]
colors = [:yellow, :orange, :red, :blue, :purple, :green]
nc = length(colors)
nδ = 1/nc
f, ax, plt = pie(data,
color = colors,
radius = 4,
inner_radius = 2,
strokecolor = :white,
strokewidth = 5,
axis = (autolimitaspect = 1, )
)
cbar = Colorbar(f[1,2], colormap = cgrad(colors, categorical = true))
cbar.ticks = (range(0+nδ/2, 1-nδ/2, nc), string.(colors))
f

Yes good idea, this works! Thanks!
But still it would be better if one could label die pieces immediately.
I also struggled with this. I ended up creating a dummy scatter plot object that matched the data points for the pie chart.
let
data = [36, 12, 68, 5, 42, 27]
colors = [:yellow, :orange, :red, :blue, :purple, :green]
f, ax, plt = pie(data,
color = colors,
radius = 4,
inner_radius = 2,
strokecolor = :white,
strokewidth = 5,
axis = (autolimitaspect = 1, )
)
for x in 1:length(data)
scatter!(ax, zeros(10), zeros(10), color = colors[x], label=string(colors[x]))
end
scatter!(ax, zeros(10), zeros(10), color = :white)
axislegend()
f
end
Would such an annotation be good enough?
