68 results about "Three-dimensional graph" patented technology

A three-dimensional graph is the graph of a function f of two variables, or the graph of a relationship g among three variables. Provided that x, y, and z or f are real numbers, the graph can be represented as a planar or curved surface in a three-dimensional Cartesian coordinate system. A three-dimensional graph is typically drawn on a two-dimensional page or screen using perspective methods, so that one of the dimensions appears to be coming out of the page.
