Contour Chart

Contour plots are graphs to show a three-dimensional surface on a two-dimensional plane. It graphs the X, Y variables on the plane axis and a response variable Z as contours. The format of the data can be specified as a three column x, y, z (long and skiny) data set or as rows and columns (short and fat) specifying the z value.
