Viewing the Waterfall Plot
After setting up the Waterfall spectra, press F4 (Display) on the Waterfall Display
Setup screen.
At the bottom of the waterfall plot is a display area that indicates the active
spectrum, and provides information (number of spacing of spectra, speed) on
how the spectra are displayed in the waterfall plot.
Cursor Movement
Use the UP and DOWN ARROW keys to sequence through the displayed
spectra. The active spectrum displays in green. The zero positions of the X and Y-
axis move to be relative to the active spectrum.
Use the LEFT and RIGHT ARROW keys to move the cursor on the active
spectrum.
Z-axis Zoom
The Z-axis zoom allows you to zoom in around the current trace. The display
area updates to indicate the number and position of the spectra displayed on the
screen. The zoom capability is only available when the No. Spectra parameter is
set to a number less than the number of extracted spectra.
See No. Spectra on page 274 .
