ApplySymbologyClassedSymbols
ApplySymbologyClassedSymbols method specifies the attributes used to define the symbology's classed symbols by bin in the VectorBaseLayer object and displays features that do not have an attribute value in the layer.

Example 1
This example defines the attributes for a class of symbols from the "FL2018.SHP" file.
Sub Main
Dim SurferApp As Object
Set SurferApp = GetObject(, "Surfer.Application")
SurferApp.Visible = True
Dim Doc As Object
Set Doc = SurferApp.Documents.Add
Set Map1 = Doc.Shapes.AddVectorBaseMap(SurferApp.Path+"\samples\FL2018.shp")
Set CSymbolsLayer = Map1.Overlays(1)
CSymbolsLayer.Name = "Classed Symbols - Not Same Class Symbols"
CSymbolsLayer.ApplySymbologyClassedSymbols(AttributeField:="MF_55-59yr", _
ShowMissingValues:=False, _
ClassMethod:=srfSymEqNum, _
Count:=5, _
ShowAllOthers:=True, _
MinimumSize:=0.15, _
MaximumSize:=0.55, _
ScalingMethod:=srfSymScalingSquareRoot, _
SameClassSymbols:=False, _
SymbolIndex:=12, _
LineColorMethod:=srfSymSColorFixed, _
LineColor:=srfColorPurple)
Example 2
This example defines the upper values of custom classes of symbols.
layer.ApplySymbologyClassedSymbols(AttributeField:="Column D", ClassMethod:=srfSymUser, Count:=4, SameClassSymbols:=False)
Set classes = layer.SymbologyClassedSymbolsBins
classes.Item(1).UpperValue = 20
classes.Item(2).UpperValue = 50
classes.Item(3).UpperValue = 100
classes.Item(4).UpperValue = 200
