    ExclusionSymbol Property (ClassBreaksRendererDefinition)
    In This Topic

    Syntax
    public CIMSymbolReference ExclusionSymbol {get; set;}
    Public Property ExclusionSymbol As CIMSymbolReference
    Example
    Create a feature layer with class breaks renderer
    string colorBrewerSchemesName = "ColorBrewer Schemes (RGB)";
    StyleProjectItem style = Project.Current.GetItems<StyleProjectItem>().First(s => s.Name == colorBrewerSchemesName);
    string colorRampName = "Greens (Continuous)";
    IList<ColorRampStyleItem> colorRampList = await QueuedTask.Run(() =>
    {
      return style.SearchColorRamps(colorRampName);
    });
    ColorRampStyleItem colorRamp = colorRampList[0];
    
    await QueuedTask.Run(() =>
    {
      GraduatedColorsRendererDefinition gcDef = new GraduatedColorsRendererDefinition()
      {
        ClassificationField = "CROP_ACR07",
        ClassificationMethod = ArcGIS.Core.CIM.ClassificationMethod.NaturalBreaks,
        BreakCount = 6,
        ColorRamp = colorRamp.ColorRamp,
        SymbolTemplate = SymbolFactory.Instance.ConstructPolygonSymbol(
                                ColorFactory.Instance.GreenRGB, SimpleFillStyle.Solid, null).MakeSymbolReference(),
        ExclusionClause = "CROP_ACR07 = -99",
        ExclusionSymbol = SymbolFactory.Instance.ConstructPolygonSymbol(
                                ColorFactory.Instance.RedRGB, SimpleFillStyle.Solid, null).MakeSymbolReference(),
        ExclusionLabel = "No yield",
      };
      var featureLayerCreationParams = new FeatureLayerCreationParams((new Uri(@"c:\Data\CountyData.gdb\Counties")))
