8.2.7 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 $x$, $y$ and $z$ coordinates in three columns. The first two are useful for producing two-dimensional representations of $(x,y,z)$ surfaces using colors or contours to show the magnitude of $z$, while the third is useful for producing three-dimensional graphs of such surfaces:

  • colormap

  • contourmap

  • surface

They are discussed in detail in Sections 8.12, 8.13 and 8.14.1 respectively.
