VarioComponent Object

The VarioComponent object encapsulates the parameters for a single variogram component. One or more variogram components are combined to form a variogram model. VarioComponents are created by the Application.NewVarioComponent method.

The following table provides all properties of the VarioComponent object. All these properties are read only.

Property	Description
AnisotropyAngle	Returns the anisotropy angle in degrees (not used for nugget).
AnisotropyRatio	Returns the anisotropy ratio (not used for nugget).
Application	Returns the application object.
LowerFitLimit	Returns the lower autofit limit for the specified parameter.
Param1	Returns the scale, slope for linear variogram, or error variance for nugget.
Param2	Returns the length (micro variance for nugget).
Parent	Returns the parent object.
Power	Returns the power used (power component only).
Type	Returns the component type.
UpperFitLimit	Returns the upper autofit limit for the specified parameter.

Following table provides all methods of the VarioComponent object:

Method	Description
Set	Sets the parameters for this variogram component.
SetFitLimits	Sets the autofit parameter limits.

Example

The following script demonstrates how the VarioComponent object is used in reference to the Application object.

Sub Main

 

'Declares SurferApp as an object

Dim SurferApp As Object

 

'Creates an instance of the Surfer Application object and assigns it

'to the variable named "SurferApp"

Set SurferApp = CreateObject("Surfer.Application")

 

'Makes Surfer visible

SurferApp.Visible = True

 

'Declares VarioComponent as an object

Dim VarioComponent As Object

 

'Creates a single variogram component and assigns it to the variable

'named "VarioComponent"

Set VarioComponent = SurferApp.NewVarioComponent(srfVarPower, Power:=1.2, _

AnisotropyRatio:=5, AnisotropyAngle:=35)

 

End Sub
