I’m trying to write an IF function that will trigger with any value of the dropdown.
This is the simplified code:
app.layout = html.Div(children=[ dcc.Dropdown(id='dpdw_filter', options=df['exam'].unique())]) @app.callback( Output(component_id='fig_line', component_property='figure'), Input(component_id='dpdw_filter', component_property='value')) def update_plot(selection): if selection is None: chart = px.line(data_frame = another_df ....
So, selection is None work fine when nothing is selected in the dropdown, now I want to change this code to the exactly opposite. I want the action to be trigger by any value of the dropdown.
if selection == value should work? For now I’m not able to make it work
