When using seriestype=:scatter, create individual labels for each dot?

I am using Plot recipes to create a plot overload for a special type of input.

The result is a scatter plot with something like:

@recipe function f(ms::MyStruct)
    seriestype --> :scatter
    ms.x_vals, ms.y_vals
end

How do I create individual labels for each of the dots? If I do e.g.

label --> "Dot " .* string.(1:length(ms.x_vals))

I get a single label like ["Dot 1", "Dot 2", ...]. Is there a way around it? I could do it with several plot commands (plot followed by plot!), but I am not sure how to combine this with plot recipes.

That put the labels on the dots themselves, but I just want an ordinary label, e.g.:

plot(1:4, 2:2:8, seriestype=:scatter; series_annotations=["A", "B", "C", "D"], label=["A", "B", "C", "D"], color=1:4)

gives

but I want something like

Transpose the vector of labels.

You need each point to be it’s own series to do that, that’s the internal logic. To create new series in a recipe, use the @series macro:

@recipe function f(ms::MyStruct)
     seriestype --> :scatter
     for i in eachindex(ms.x_vals)
         @series begin
             label := "Dot $i"
             ms.x_vals[i:i], ms.y_vals[i:i]
         end
     end
end

Thanks a lot, that works :slight_smile:
