Select the 3D View check box if you would like to show a time history of FFT
spectra or histograms on the screen. The Number of Plots value can be set to
choose how many records will be shown on the screen at the same time. The
newest record is shown at the front of the display with the oldest record at the
back. As the screen updates you see a new record appear at the front, then
move its way to the back as newer records arrive, until it finally becomes older
than the last record shown and disappears. Select the Color Each Plot check
box to have each spectrum drawn wit a unique color.
