What are Contour Plots / Surface Charts in Excel
The contour chart is part of the contour plot in excel that is used to display the set of three-dimensional data in the form of a Mesh surface. This chart can be used to find the optimum combination of two sets of data points. These charts can be constructed by using three kinds of variables i.e., “X, Y, and Z.” Out of these three variables, two are being independent, which are plotted on the horizontal axis, and the remaining variable is independent, which occupies the vertical axis. So this chart shows the relationship between data points.
