Unable to Append seasonality graphs to Dash

Dash Python
1

Hi there, I’m trying to append a seasonality graph per unique Finished Good. It works when I use 1 item code however when I try and append multiple unqiue items to the html.Div called seasonal-chart it wont dislay.

I was using this How to plot multiple graphs/plots in a for loop in a Dash app? - #9 by vivekvs1 as a refernece but am unable to make it work in my case.

Let me know if there is any additional info i can provide

@callback(
    Output('indicator-graphic', 'figure'), 
    Output('Datatable2', 'children'),
    Output('indicator-graphic2', 'figure'), 
    Output('seasonal-chart', 'children'), 
    Input("dataTable", "selected_rows")
)

            DFPointer2 = FGgoodsSeason.query("Trunc == @product").set_index('TrnDate')
