I am trying to build a bar chart using dash plotly and while the dropdown is getting selected, it is unable to refresh the page with the selected value from dropdown. I am new to Dash. Any help will be appreciated.The graph is ok with the defult value being selected (that is "FII’ in this case), however the moment I select different value ( I have FII,DII,Pro,Total) values in Client\_Type.

```auto
 df = df1[df1['Month'].isin([2,3])]
    app = dash.Dash()
    df = df1[df1['Month'].isin([2,3])]
    app = dash.Dash()
    party_data = []
    for client in df['Client_Type'].unique():
         party_data.append({'label': client, 'value': 'Client_Type'})

   app.layout = html.Div([
   dcc.Graph(id='graph'),
   dcc.Dropdown(id='client-picker',options=party_data,value= 'FII' )

```

])

```auto
  @app.callback(Output('graph', 'figure'),
          [Input('client-picker', 'value')])
def update_figure(abc):
df1 = df[df.Client_Type == abc]
print(df1.head())
date1 = df1['Date']
Fut_Index_Long1 = df1['Fut_Index_Long']

return {
    'data': [go.Bar(x=date1, y=Fut_Index_Long1)]
}

   if __name__ == ' __main__':
app.run_server(debug=True)

```
