The Signals tab displays techniques associated with workbooks that have triggered signals.

Components of Signal Tab

Signal Count	Total number of signals generated from workbooks associated with a particular technique (in the last 7 days by default).
Legend	The color coding represents the ratio of the total signal count for each technique to the sum of all signal counts, displayed as a percentage across the selected duration.

Filtering over Signal Activity:

• 1 Day: Shows signal activity for the current day.
  
  
  
  
  
  
  
• 7 Day:  Shows Signal Activity over the last 7 days. (default time filter)

Visualizing the Signal Activity by Timeline

Displays a line chart of signal activity over the selected duration (default: 7 days). Users can view signal counts for specific days or times. By clicking on a workbook name in the list, its data line is highlighted, allowing users to investigate signal activity for the selected workbook. (Note: To deselect a workbook, double-click its name.)
