The CreateHatchMap method creates a hatch map. Hatch map properties are edited through the returned HatchMap object.

Syntax

object.CreateHatchMap( BoundaryFileName, DataFileName, DataTableName, BoundaryFileOptions, PIDCol, VarCol, NumClasses, NoData, AllOther )

Parameter	Type	Description
BoundaryFileName	String	optional; boundary file name
DataFileName	String	optional; data file name
DataTableName	String	optional; table name if a database file is used
BoundaryFileOptions	String	optional; see Boundary File Options
PIDCol	Integer	optional; primary ID column, column A equals 1
VarCol	Integer	optional; variable column, column A equals 1
NumClasses	Integer	optional; number of classes

Example

This example creates a hatch 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)

'Creates a hatch map object and assigns it to the variable named "HatchMap"

Set HatchMap = Plot.CreateHatchMap( BoundaryFileName:= InPath$ + _

"co2010.gsb", DataFileName:= InPath$ + "co2010.dat", PIDCol:=1, VarCol:=5, _

NumClasses:=4)
