Hi All,

I’m very new to Dash…!

below is my code for the layout

```auto
import dash
import dash_bootstrap_components as dbc
import dash_html_components as html
from dash.dependencies import Input, Output, State

app = dash.Dash(external_stylesheets=[dbc.themes.CERULEAN])

app.layout = html.Div(
    html.Div([ html.Div(id='live-update-table'), 
        dcc.Interval(
            id='interval-component',
            interval=1*60000, # in milliseconds
            n_intervals=0
        )
    ])
)

```

Below is the callback

```auto
@app.callback(Output('live-update-table', 'children'),
              [Input('interval-component', 'n_intervals')])
def update_metrics(n):
    navbar = navbars()
    table1 = servstat()
    table = capperf()
    dbtble=gettblperc()
    row = html.Div(
    [
        dbc.Row( # Headings #
            [dbc.Col([html.Img(src='assets/services.jpg', height="55px", style={'float': 'left'}),html.H4("Services",style={'color': 'green','text-align': 'center'})],width=2),
                dbc.Col([html.Img(src='assets/Performance.png', height="55px", style={'float': 'left'}),html.H4("Performance",style={'color': 'green','text-align': 'center'})],width=3),
                dbc.Col([html.Img(src='assets/Storages.png', height="55px", style={'float': 'left'}),html.H4("Storage",style={'color': 'green','text-align': 'center'})],width=3),
                dbc.Col([html.Img(src='assets/Database.png', height="55px", style={'float': 'left'}),html.H4("Database",style={'color': 'green','text-align': 'center'})],width=4),
                ],
            style={'margin': 'auto'},
            ),
        dbc.Row( # Services, Performance, Storage, Database details
            [ dbc.Col(table1, width=2),
              dbc.Col(table, width=3),
              dbc.Col(dbtble, width=3),
              ],
            style={'margin': 'auto'},
            justify="center"
            ),
        ]

    )
    return navbar, row

```

the issue is the layout load only after the interval i.e… after 1 mins on every refresh… I want to display the layout 1st and update the same with the interval of 1 mins. please help…
