Insert Variogram Fans

Variogram fans can be inserted under any assay or domain type in your project. Variogram fans can also be inserted under a Data Loader Component, but an assay must be selected.

There are three levels of variogram fans that must be inserted below each other in the Project Tree. These are the horizontal fan, across-strike fan and dip-plane fan. For more information on selecting the maximum continuity direction, see Selecting the Direction of Maximum Continuity on Variogram Fans.
