The CreatePieMap2 method creates a pie map. Pie map properties are edited through the returned PieMap object. This method is the same as the CreatePieMap method, except it takes the pointer to the array. VB users may want to call this method instead of CreatePieMap. Note: Golden Software does not officially support VB.
Syntax
Object.CreatePieMap2( ppVarCols, BoundaryFileName, DataFileName, DataTableName, BoundaryFileOptions, PIDCol )

Example
This example creates a pie map of Colorado.
Sub main
'Creates an instance of the MapViewer Application object
'and assigns it to the variable named "mvApp"
Set mvApp = CreateObject("MapViewer.Application")
'Makes the application main window visible
mvApp.Visible = True
'Assigns the location of the samples folder to the variable "InPath"
InPath$ = mvApp.ApplicationFolder + " samples\"
'Creates a map document object, and assigns it to the variable named "Plot"
Set Plot = mvApp.Documents.Add(DocType:=mvDocPlot)
'Defines the variables for a pie map
Dim Variables(1 To 3) As Long
Variables(1) = 4
Variables(2) = 8
Variables(3) = 6
'Creates a pie map object and assigns it to the variable named "PieMap"
Set PieMap = Plot.CreatePieMap2( Variables, BoundaryFileName:=InPath$ + _
"co2010.gsb", DataFileName:=InPath$ + "co2010.dat", BoundaryFileOptions:= _
"SecondaryIDField=2, Attribute1Field=1", PIDCol:=1 )
End Sub
