Definition
Shows the relationship between three variables as a smooth surface. It's a useful tool for exploring how variables interact.

"Two three-dimensional surface plots show voltage as a function of current and geometry. In panel a, voltage is about 28 volts at low airgap width and falls steeply as airgap width increases toward 3 millimeters, with a smaller change across current from 0 to 7 amperes. In panel b, voltage rises from about 22 to 31 volts as P M height increases from 0 to 25 millimeters, while increasing current slightly lowers voltage."
