{{Dablink|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 in which showsmultiple gridcurves linesof fordata, onlytypically onespectra, ofare displayed simultaneouly. Typically the axescurves 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, resembling a waterfall. 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.
