The setting chosen is the amount of time covered by one full horizontal swipe across the screen.

For example:

  • 50% range: one full swipe will move through half the number of days displayed.
  • 36 hours: one full swipe will move through 36 hours.
  • 4 days: one full swipe will move through 4 days.
