A '''Waterfallwaterfall plot''' is a [[three-dimensional plot]] in which multiple curves of data, typically [[spectra]], are displayed simultaneously. Typically the curves are staggered both across the screen and vertically, with 'nearer' curves masking the ones behind. The result is a series of "mountain" shapes that appear to be side by side. The waterfall plot is often used to show how two-dimensional information changes over time or some other variable such as [[rpm]]. The term "waterfall plot" is sometimes used interchangeably with "[[spectrogram]]" or "Cumulative Spectral Decay" (CSD) plot.
