The problem comes from the way Dash.jl process the data. Instead of considering matrices as in PlotlyJS.jl, Dash.jl needs X,Y,Z to be defined as Vectors of Vectors.

Here, the plot3D function must be as follows:

function plot_3D(x, y, z)
    nx = length(x)
    nv = Int(round(nx./2.))

    vl = range(0., 1., nv)
    v = repeat(vl, 1, nx)
    X = repeat(x', nv, 1)
    XX =  [c for c in eachcol(X)]

    zmin = minimum(z)

    traces = GenericTrace[]
    Y = y*ones(size(X))
    YY = [c for c in eachcol(Y)]

    # Line
    trace = scatter3d(x = x,
                    y = Y[1, :],
                    z = z,
                    mode = "lines",
                    line = attr(color = :blue),
                    showlegend = false)

    # Surface
    Z = zmin .+ (repeat(z', nv, 1) .- zmin).*v
    ZZ = [c for c in eachcol(Z)]
    surf = surface(x = XX,
                    y = YY,
                    z = ZZ,
                    showscale = false)

    append!(traces, [trace, surf])

    # Define the layout
    layout = Layout(scene = attr(
        xaxis = attr(autorange = "reversed")))

    p = plot(traces, layout)
    figure = (data = getfield.(p.plot.data, :fields), layout = p.plot.layout.fields)

    return figure
end

from dash.jl.

thanks for writing down the workaround @maucejo 👏

from dash.jl.
