Eureka Overview

• Technology table lens based on the principle of
  focuscontext
• Allows users to do (Features)
• view an entire dataset on one screen
• zoom in to focus on individual record values
• easily navigate large datasets
• public a table lens on the web
• click columns to sort by them
• group records by column variables
• spotlight individual records to track them when
  you sort
• filter out data subsets

Outline of demonstration

• Focusing on Data
• Managing data displaying
• Finding data pattern (sorting, grouping,
  spotlighting, filtering)
• A few examples ( the number depends on our time)

4
Focusing on Data

• Tools menu and setting preferences
• Focus a cell
• focus multiple cells
• focus a row
• focus multiple rows
• value-attached focus vs. grid-attached focus
• change the focus type (click the cell of row
  number column)
• focus columns (right-click the column heading,
  then focus)
• change the focus size (resize handles)
• move a focus (click new rows, use focus control
  bar)
• remove a focus (remove all, remove one row or
  column)

5
Managing the data display

• Data mapping options
• mapping mode
• non-uniform mode
• if there are more records than vertical
  pixels on the screen, records are combined
  non-uniformly-- some rows may represent more
  records than other rows.
• uniform without scroll mode
• records are combined such that the of
  records represented in each row is the same
  throughout the table lens.
• uniform with scroll mode
• if there are more records than there are
  vertical pixels on the screen, records are not
  combined.
• combining option (min displays the lowest of the
  combined values)
• min, max, average, min and max, min and median

6
Managing the data display

• showing or hiding data
• hiding columns unhiding columns
• resizing focused columns
• (click on focus and drag the left or right
  border in the column heading)
• expanding rows or columns (using span controls)
• only used in non-uniform mapping mode (rows)
• span controls in column can used in any mode
• clear a single span control (clicking on it)
• clear all the span controls (view menu, toolbar)

7
Managing the data display

• changing column data display
• change column name (click column heading, column
  properties)
• change column data type
• change date format
• change number format
• group dates into categories
• group numbers into categories
• change category color and sort order settings

8
Finding data pattern

• Sorting data
• restoring the original row order (view menu or
  toolbar)
• moving columns
• grouping columns (one or more)
• spotlighting data (next)
• filtering data (next)

9
Finding data pattern

• Spotlighting data
• spotlight a cell
• spotlight a selection
• spotlight a group
• spotlight column values
• spotlight a range of dates
• spotlight a range of numeric values
• spotlight a category
• clear a spotlight

10
Finding data pattern

• Filtering
• filtering a selection
• filtering a group
• filtering column values (click column heading)
• filter a range of dates
• filter a range of numeric values
• filter a category
