the bottom of the ‘Data Visualization’ pane. A new ‘Sleep Analysis’ pane will appear with two
sections: (1) Sleep Analysis and (2) Lying Position. Sleep quality is determined by the amount of
movement, or restlessness, collected by the sensor during periods of sleep. The greater the number

can be checked to link the times in the two graphs so that zooming one graph will change the time
axis on both graphs.

Expenditure, which can be viewed as METS or Calories/hr.
