The Variograms Window, accessed from the Autocorrelation Window, presents a full-window isotropic and anisotropic variograms that can be edited and printed. Additionally, the semivariance values that were used to produce the variogram can be listed, and Variance Cloud Analysis and h-Scattergram Analysis can be performed. Variance Clouds and h-Scattergrams provide an easy way to detect outlier pairs of points that may be artificially skewing the variogram.
You can use the mouse cursor to identify the number of pairs in specific lag classes. In the example below, the cursor is over the next to last graph symbol and at the bottom of the screen wetold that this is Lag Class 9 with 533 pairs of points. You can double-click on a symbol to being Variance Cloud or h-Scattergram analysis.
Note also that parameters for the variogram model (if present) are presented in a graph footnote. If you do not want parameters to appear as a footnote you must use the Edit Graph command to bring up the Graph Settings dialog and in the Footnote field remove the notation “(model results)”.
You may Print, Copy, Edit, Export, or List graph values for either graph using the menu commands of the main GS+ window, or via a right-click menu.
Create a Variance Cloud or h-Scattergram graph for a particular lag interval in a separate window.
