Waterfall plot
Appearance
A Waterfall plot is a three-dimensional plot which shows grid lines for only one of the axes. The result is a series of "mountain" shapes that appear to be side by side, resembling a waterfall. The waterfall plot is often used to show how two-dimensional information changes over time or some other variable. The term "waterfall plot" is sometimes used interchangeably with "spectrogram" or "Cumulative Spectral Decay" (CSD) plot.
Uses
Waterfall plots are often used to show the:
- results of spectrum analysis, showing the spectrum of the signal at successive intervals of time.
- delayed response from a loudspeaker or listening room produced by impulse response testing or MLSSA.
- spectra at different engine speeds when testing engines.
