Each measurement is stored in an imaginary layer. By default, the first measurement is the bottom layer and the most recent measurement is the top layer. You can change the order of the layers, for example if two measurements overlap and one is obscuring the other.

To move a measurement up or down a layer:

  1. Right-click the measurement.
  2. Select how you want to move the measurement:
  3. Bring Forwards: up one layer
  4. Send Backwards: down one layer
  5. Bring to Front: to top
  6. Send to Back: to bottom
