Key Components and Features –
Grouping


In Eureka a Table Lens allows you
to group records by the variables
within a column.
Grouping divides the Table Lens
into sub-tables that sort or filter
independently.
Key Components and Features –
Grouping
Question:
Can you Group your data by certain
Category of data or column Y.
Key Components and Features - Filtering

The Filter command allows you to
filter a subset of data and work
with it in a separate window. You
can filter selected cells, a group of
records, or records with particular
values.
Key Components and Features –
Filtering
Question:
Find the data that fits the conditions,
“X, Y and Z”.
Key Components and Features –
Sorting


In Eureka, sorting is an especially
powerful data analysis tool for
identifying patterns and relationships
between variables.
After sorting, you can tell at a glance if
relationships exist between the sorted
column and other column variables.
Key Components and Features Sorting
Question:
Please sort data by column X, and by
Group Y.
Key Components and Features –
Spotlighting


You can visually track records by
spotlighting data that interests you.
The cells are marked with a
persistent magenta highlight that
follows the data as you sort and resort the Table Lens.
Key Components and Features –
Spotlighting
Question:
Can you “spotlight” the data set that
you want to keep track of?
