New data is added to the plot starting on the left and progressing to the right. When the
plot has progressed to the right edge, the plot restarts on the left side of the plot. One line
of data from the previous plot is removed ahead of the new plot.
When a new screen is selected, the plot is displayed using a default plot range. Pressing
the CLEAR soft key restarts the plot and clears all previously plotted data and calculated
statistics. Pressing the RESCALE key changes the window of the data plot to a more
appropriate range based on the minimum and maximum values in the Statistics area.
Note
After pressing CLEAR , allow one full cycle to pass before pressing
RESCALE .

following every breath. Units of measure for breath parameters are fixed. See
Introduction: Specifications for a listing of breath parameters and units. See Selecting
Breath Parameters for instructions on selecting which parameters are displayed for each
of the modes.
