CreateBarMap

The CreateBarMap method creates a bar map. The bar map properties are edited through the returned BarMap object.

Syntax

object. CreateBarMap( pVarCols, BoundaryFileName, DataFileName, DataTableName, BoundaryFileOptions, PIDCol )

Parameter	Type	Description
pVarCols	Array of Longs	required; array of variable column numbers, column A equals 1
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; number of primary ID column, column A equals 1

Remarks

VB users can use ReDim to set the array size to the used size if necessary or use CreateBarMap2.

Example

This example creates a bar map of Indiana.

Sub Main

'Declare the variable that will reference the application

Dim mvapp As Object

'Creates an instance of the MapViewer Application object

'and assigns it to the variable named " mvapp"

Set mvapp = CreateObject("MapViewer.Application")

'Make MapViewer visible

mvapp.Visible = True

'Declare Plot as Object

Dim Plot As Object

'Creates a new map window

Set Plot = mvapp.Documents.Add(mvDocPlot)

'Declare BarMap as object

Dim BarMap As Object

'Create a bar map

Dim pVarCols(1) As Long

pVarCols(0) = 4 : pVarCols(1) = 5

Set BarMap = Plot.CreateBarMap(pVarCols(), _

BoundaryFileName:= mvapp.ApplicationFolder + "\Samples\in2010.gsb", _

DataFileName:= mvapp.ApplicationFolder + "\Samples\in2010.dat", PIDCol:=1)
