contour map is A 2D diagram for visualizing multivariable functions (or surfaces) with a 2D input and 1D output, for example:
Transforming a 3D graph to a contour map
- Graph the function in a 3D space
- Slice the graph with a few evenly-spaced level planes, each of which should be parallel to the
-plane. Imagine these planes have positions of - Mark on the graph where the planes cut
- Project these lines onto a plane, and label the heights they correspond to.
- The contour map looks like
