Rodograms

Rodograms are similar to traditional variograms (see Semivariance Analysis), except that the square root of the difference between zi and z i+h is calculated rather than the square of the difference. The formula thus becomes

Rodograms (both isotropic and anisotropic) appear in the Autocorrelation Window, on the Rodogram tab. Pressing the Expand button on this tab brings up the Rodograms window:

The Cloud/Scatter, right-click menu, and other commands work here as they do for the Variograms Window.
