Interactive key stats table
Using graphs to display your data visually is a great way to visually see aggregated figures. Yet sometimes, you also need to see more numbers than is feasible to display in common visualization formats.
A key stakeholder in the e-commerce company, the finance department head, has heard of your great work but is someone who needs to see some figures in tabular rather than visual format. He has requested a dashboard displaying some aggregated stats in a tabular format. However, he wonders if you could also include some 'Dash magic' to make it a bit more interactive than his existing Excel spreadsheets?
This exercise is part of the course
Building Dashboards with Dash and Plotly
Exercise instructions
- Set up the
money_fmt
object for USD currency formatting below line9
using the appropriate function and style parameters. - Add the
money_fmt
formatter to the'Total Sales ($)'
column in thecolumn_defs
below line15
.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.

key_stats_tb = ecom_sales.groupby(['Country','Major Category', 'Minor Category'])['OrderValue'].agg(['sum', 'count', 'mean']).reset_index().rename(columns={'count':'Sales Volume', 'sum':'Total Sales ($)', 'mean':'Average Order Value ($)'})
# Set up the money object

# Add the formatter to the relevant column
column_defs = [
