updatemenus key not supported?

[iuliancioarca]

I would like to create animations with Dash but I'm stuck at displaying the simple Play button in the Layout. Is the "updatemenus" key not available in the Julia version?

`
app = dash()
app.layout = html_div() do
html_div(html_button("Plot", id="b1")),
html_div(dcc_graph(id="g1"))
end

callback!(
app,
Output("g1", "figure"),
Input("b1", "n_clicks")
) do nc

tall = 0:1e-3:1
yall = randn(length(tall))
data = scatter(;x=tall,
y=yall,
mode="lines")

layout = Layout(;
#yaxis_range = [-100, 100],
xaxis_type = "linear",
xaxis_title = "t [s]",
yaxis_title = "y []",
title="Primary Graph",
legend_x = 1,
legend_y = 1,
hovermode = "closest",
hoverlabel=(font=(size=10,),font_family="Rockwell"),
transition_duration = 5,
updatemenus=[(visible=true, type="buttons", buttons=(label="Play", method="animate", args=[nothing]))]
)

return Plot(
data,
layout,
[frame(name="a", data=data)]
);
end
run_server(app, "0.0.0.0", 8080, debug=true)
`

buttons property of updatemenus must be an array. As well as data in frame. See, for example, this docs: https://plotly.com/python/animations/
A working example of what you wanted here:

using Dash, Printf, PlotlyJS

app = dash()
app.layout = html_div() do
    html_div(html_button("Plot", id="b1")),
    html_div(dcc_graph(id="g1"))
end

callback!(
    app,
    Output("g1", "figure"),
    Input("b1", "n_clicks")
) do nc

    tall = 0:1e-3:1
    frames = PlotlyFrame[]
    yall = randn(length(tall))
    data = [scatter(;x=tall,
        y=yall,
        mode="lines")]
    for i in 1:5
        yall = randn(length(tall))
        push!(frames, frame(name="a$(i)", data =
            [scatter(;x=tall,
                y=yall,
                mode="lines")]
        ))
    end

    layout = Layout(;
    #yaxis_range = [-100, 100],
        xaxis_type = "linear",
        xaxis_title = "t [s]",
        yaxis_title = "y []",
        title="Primary Graph",
        legend_x = 1,
        legend_y = 1,
        hovermode = "closest",
        hoverlabel=(font=(size=10,),font_family="Rockwell"),
        transition_duration = 5,
        updatemenus=[
            (   visible=true,
                type="buttons",
                buttons=[(label="Play", method="animate", args=[nothing])]
            )
        ]
    )

    return Plot(
        data,
        layout,
        frames
    );
    end
run_server(app, "0.0.0.0", 8080, debug=true)
