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".

Uses

  • Waterfall plots are often used to show the results of spectrum analysis, showing frequency impulse vs. time.
  • Waterfall plots are often used to show the delayed response from a loudspeaker or listening room produced by impulse response testing or MLSSA.
  • Waterfall plots can be used to show the frequency impulse for different engine speeds when testing engines.
