Filter Other Elements to Data Selected in Mito

Subscribe to the spreadsheet_selection to enable cross filtering


  1. A user uses a Mito spreadsheet to select a few specific rows or columns.

  2. You want to display a graph somewhere else in your dashboard, just based on these few rows or columns.

Crossfiltering using the Mito spreadsheet component

First, set the track_selection parameter in the Spreadsheet component to True.

Simply use the @mito_callback to watch for changes on the spreadsheet_selection prop.

Notably, the spreadsheet_selection return type will return a Pandas dataframe that corresponds to the selected data in the sheet.

Example: changing a graph based on the current selection in a Mito spreadsheet

from dash import Dash, html, dcc, Output, Input
from dash.exceptions import PreventUpdate
import as px
import pandas as pd

from mitosheet.mito_dash.v1 import Spreadsheet, mito_callback, activate_mito

df = pd.read_csv('')

app = Dash(__name__)

app.layout = html.Div([
    Spreadsheet(df, id={'type': 'spreadsheet', 'id': 'sheet'}, track_selection=True),

    Output('graph-content', 'figure'),
    Input({'type': 'spreadsheet', 'id': 'sheet'}, 'spreadsheet_selection')
def update_code(spreadsheet_selection):
    if spreadsheet_selection is None:
        raise PreventUpdate

    # Get selected rows from the original dataframe
    index = spreadsheet_selection.index
    dff = df.loc[index]

    return px.line(dff, x='year', y='lifeExp', color='continent')
