This page refers to a type of 3D graph representation, for the 2D floating column diagram showing increases and decreases, see waterfall chart.
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".
[edit] 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.
