Graph New Data after Edits to Mito

Build dynamic graphs that update to your users's Mito edits.


  1. A user is filtering a dataset using a Mito sheet.

  2. You want to update a graph of this data elsewhere in your dashboard.

How to:

Simply use the @mito_callback to watch for changes on the spreadsheet_result prop, and then graph the resulting dataframe.

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'}),

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

    # Get the current value of the original dataframe
    dff = spreadsheet_result.dfs()[0]
    # Requires that the user doesn't delete the year, lifeExp, or continent column
    return px.line(dff, x='year', y='lifeExp', color='continent')

if __name__ == '__main__':

Now, if the user filters the original data in any way, the new data will be displayed on the page.
