  1. Table Lens A new way to view data tables

  2. Table Lens • Increase information density • A magnifying glass without distortion • Promotes easy scanning • Combines graphical and textual • focal data is textual • nonfocal data is graphical

  3. Increased Information Density • Spreadsheets focus on all data, requires one character height for all cells. • Table Lens focuses only on some data, allowing most cells one pixel height. • Users can process general trends of more data.

  4. Enlarge focal cells and maintain rectangular shape. Keeps nonfocal cells from being distorted Focus on entire cells, no fragments A magnifying glass without distortion

  5. Easy scanning • Graphical instead of textual • Easier to process bar graphs than numbers • Easily recognize trends

  6. Terms • Degree of Interest • Focal, row focal, column focal, nonfocal • Zoom, adjust, slide • transfer function

  7. What it’s good for • Proportional data • order of 10’s of dimensions • order of 100’s of variables • examining data for trends, outliers, relationships

  8. What it’s not good for • Entering data, like in Excel • Nominal values, name of team • Can be difficult to select a desired cell, e.g. the row for player “Bill Buckner”
