## 1.2.7 Color maps, contour maps and surface plots

The following plot styles differ from those above in that, regardless of whether a three-dimensional plot is being produced, they read in datapoints with , and coordinates in three columns. The first two are useful for producing two-dimensional representations of surfaces using colors or contours to show the magnitude of , while the third is useful for producing three-dimensional graphs of such surfaces:

- colormap

- contourmap

- surface

They are discussed in detail in Sections 1.12, 1.13 and 1.14.1 respectively.
