Am trying to make a dash dashboard with a datepickerrange but its returning numbers instead of dates, would really appreciate it if someone could let me know where i am going wrong thanks 
import pandas as pd
import dash
import dash_html_components as html
import dash_core_components as dcc
from datetime import datetime as dt
df = pd.read_csv(‘kaiterradf.csv’)
df[‘Time’] = pd.to_datetime(df[‘Time’])
df = df.set_index(‘Time’)
initialize the application
app = dash.Dash()
define the layout of the app
app.layout = html.Div([
# add a date range selector
dcc.DatePickerRange(
id = 'my-date-picker-range',
min_date_allowed = dt(2020, 12, 1),
max_date_allowed = dt(2020, 12, 31),
initial_visible_month = dt(2020, 12, 1)
),
dcc.Graph(id='myfig'),
])
@app.callback(
dash.dependencies.Output(‘myfig’, ‘figure’),
[dash.dependencies.Input(‘my-date-picker-range’, ‘start_date’),
dash.dependencies.Input(‘my-date-picker-range’, ‘end_date’)])
def update_output_div(start_date, end_date):
return {
‘data’: [go.Scatter(
x=df.loc[start_date:end_date],
y=df[‘Temperature’],
mode=‘lines’,
)]
}
app.run_server()
CSV file:
