Problem  Eclipse usage data from Mylar user study  XML  Up to 4 months of data  Event per selection

Solution  Mylog  Visualization of the log data  Implemented in Java 5.0  Prefuse Visualization ToolKit  Swing UI  Launched from Eclipse

Solution  Sequential Visualization  Aggregation  Bifocal lens  Filtering  Highlighting

Demo

Evaluation  Performance  Slow interaction for 10, nodes  Color  Vischeck for all 3 (Deuteranope, Protanope, and Tritanope)

Problems Encountered  SWT and Swing do not work well together  Hard to choose colors to suit all potential users  Tooltips disappear when refresh is run  Poor performance with a large number of nodes

Future Work  Add support for multiple users  Automatically determine sequences  Allow user customization of colors and aggregation  Allow investigation of multiple items at one time
