MethodError when using partitionplot

[stillill]

When I run this code taken from the JuliaDB docs--

using JuliaDB, Plots, OnlineStats

x = randn(10^6)
y = x + randn(10^6)
z = x .> 1
z2 = (x .+ y) .> 0
t = table((x=x, y=y, z=z, z2=z2));

partitionplot(t, :x, stat = Extrema())

I get the following error:

MethodError: Cannot convert an object of type Vector{Int64} to an object of type RecipeData

I'm using Julia 1.6.1 and JuliaDB v0.13.0.
