how to send in parameter for app.callback function for plotly dash?

Question

I would like to create mulitiple graphs that send in a different parameter to 'INPUT_PARAM' in the update_graph_scatter function. Where do I pass in the INPUT_PARAM?

app.layout = html.Div(
    [
        dcc.Graph(id='live-graph', animate=True),
        dcc.Interval(
            id='graph-update',
            interval=1000 * 60,
            n_intervals = 0,
        ),
    ]
)

@app.callback(Output('live-graph', 'figure'),
        [Input('graph-update', 'n_intervals')])
def update_graph_scatter(INPUT_PARAM):

That is controlled by the Input values and State values you define in the app.callback decorator. In this case, it would be the n_intervals from graph-update.

help please Over a year ago

I see, but I want to pass in a string to load a different type of graph. Will I need to create a new function then?

What string would you want to pass and and how would you want it to update the graph?

I'm using the string passed in to query a database and return a graph of the queried word

Where would that string be coming from? Is the user submitting it? Then you might want dcc.Input for that.
