i’m writing a code with a sunburst chart that will present all classes from some type of data, and when the user click on what class he wanna see my dropdown menu should present values only from that classe.
So, my difficult where how to do this callback, cause all the ways that i tried failed.
my df used look like this
df = {'Nome': ['Aberdeen Multi Asset Growth Advisory FIM IE',
'Absolute Alpha Global Advisory FIC FIM',
'Absolute Alpha Marb Advisory FIC FIM',
'Absolute Hedge FIC FIM',
'Claritas Hedge Advisory FIC FIM Longo Prazo',

'Sharp Equity Value Advisory FIC FIA',
'Vinland Macro Advisory FIC FIM'],

'Renda Variável Long Only',
'Macro Média Vol',
],
'retorno 1 mês':[ '0,79%',
'0,38%',
'0,40%',
'0,38%',
'0,82%',
'4,11%',
'4,02%',

'0,72%'],
'classes' :
[
'Internacional Multimercado Hedgeado',

'Macro Média Vol',
'Renda Variável Long Only',

'número de fundos':
['8',
'6',
'10',
'59',
'37',
'30',
'10',
'15',
'11'
]
}
df = pd.DataFrame(df)
app = Dash(__name__, external_stylesheets= [dbc.themes.DARKLY])
app.layout = dbc.Container(

Answer
You can try to use this code below:
Full example:
import dash
import dash_bootstrap_components as dbc
from dash import Dash, html, dcc,dash_table
from dash.dependencies import Input, Output
import plotly.express as px
import pandas as pd
# dff_dict = ..... add here the dictionary
dff = pd.DataFrame(dff_dict)
app = dash.Dash(__name__)
fig = px.pie(dff, values = 'número de fundos', names = 'tipo', title = 'Teste' )
app.layout = dbc.Container(
dbc.Row([
dbc.Col([
#First Div, where objective of dashboard be presented
#This piece also include our logo on left side
#Few personalization options, simple template
html.Div([
html.Img(id='logo_png', src=app.get_asset_url("logo.png"), height= 50),
html.H5("Os fundos que acompanhamos estão dividos nas seguintes abaixo"),
#Phrase below our pie chart
html.P('Selecione a classe que deseja obter mais informações'),
#Pie chart id created inside this .Div
html.Div([
dcc.Graph(id = 'pie_class_chart', figure = fig,
style={'width': '100%', 'display': 'inline-block', 'vertical-align': 'right', })
]),
dbc.Col(
html.Div([
dash_table.DataTable(
id = 'tabela-dash',
columns = [{"id": i, "name": i} for i in dff.columns],
style_table={'height': '515px', 'overflowY': 'auto', 'display': 'inline-block', 'vertical-align':'left', 'float': 'left'},
style_data={
'color': 'black',
'backgroundColor': 'white'},
page_size= 15
)
]),
),
]),
#Options of windowns, with click buttons
]),
]),
)
#callback of datatable values
@app.callback(
Output(component_id="tabela-dash", component_property='data'),
Input(component_id = 'pie_class_chart', component_property='clickData'))
def display_click_data(clickData):
if clickData != None:
value = clickData['points'][0]['label']
return dff[dff['tipo'] == value].to_dict('records')
return dash.no_update
app.run_server(debug=True, use_reloader=False)
Output
