    ClassificationMethod Property (TinColorRampRendererDefinition)
    In This Topic
    Gets or sets the classification method to be used to compute class breaks. The default value is ArcGIS.Core.CIM.ClassificationMethod.EqualInterval.
    Syntax
    public ClassificationMethod ClassificationMethod {get; set;}
    Public Property ClassificationMethod As ClassificationMethod
    Example
    Create a TinLayer with renderers
    //Must be on the QueuedTask.Run()
    
    var tinCP_renderers = new TinLayerCreationParams(tinDataset);
    tinCP_renderers.Name = "My TIN layer";
    tinCP_renderers.IsVisible = true;
    
    // define the node renderer - use defaults
    var node_rd = new TinNodeRendererDefinition();
    
    // define the face/surface renderer
    var face_rd = new TinFaceClassBreaksRendererDefinition();
    face_rd.ClassificationMethod = ClassificationMethod.NaturalBreaks;
    // accept default color ramp, breakCount
    
    // set up the renderer dictionary
    var rendererDict = new Dictionary<SurfaceRendererTarget, TinRendererDefinition>();
    rendererDict.Add(SurfaceRendererTarget.Points, node_rd);
    rendererDict.Add(SurfaceRendererTarget.Surface, face_rd);
    
    // assign the dictionary to the creation params
    tinCP_renderers.RendererDefinitions = rendererDict;
    
    // create the layer
    var tinLayer_rd = LayerFactory.Instance.CreateLayer<TinLayer>(tinCP_renderers, MapView.Active.Map);
    Create a TerrainLayer with renderers
    //Must be on the QueuedTask.Run()
    
    var terrainCP_renderers = new TerrainLayerCreationParams(terrain);
    terrainCP_renderers.Name = "My LAS Layer";
    terrainCP_renderers.IsVisible = true;
    
    // define the edge type renderer - use defaults
    var edgeRD = new TinBreaklineRendererDefinition();
    
    // define the face/surface renderer
    var faceRD = new TinFaceClassBreaksRendererDefinition();
    faceRD.ClassificationMethod = ClassificationMethod.NaturalBreaks;
    // accept default color ramp, breakCount
    
    // define the dirty area renderer - use defaults
    var dirtyAreaRD = new TerrainDirtyAreaRendererDefinition();
    
    // add renderers to dictionary
    var t_dict = new Dictionary<SurfaceRendererTarget, TinRendererDefinition>();
    t_dict.Add(SurfaceRendererTarget.Edges, edgeRD);
    t_dict.Add(SurfaceRendererTarget.Surface, faceRD);
    t_dict.Add(SurfaceRendererTarget.DirtyArea, dirtyAreaRD);
    
    // assign dictionary to creation params
    terrainCP_renderers.RendererDefinitions = t_dict;
    
    //Create the layer to the terrain
    var terrainLayer_rd = LayerFactory.Instance.CreateLayer<TerrainLayer>(terrainCP_renderers, map);
    LAS Points Classified Elevation Renderer
    // applies to LAS dataset layers only
    
    var lasPointsClassBreaksRendererDef = new LasPointClassBreaksRendererDefinition();
    lasPointsClassBreaksRendererDef.ClassificationMethod = ClassificationMethod.NaturalBreaks;
    lasPointsClassBreaksRendererDef.ModulateUsingIntensity = true;
    // increase the symbol size by a factor
    lasPointsClassBreaksRendererDef.SymbolScaleFactor = 1.0;
    
    if (lasDatasetLayer.CanCreateRenderer(lasPointsClassBreaksRendererDef))
    {
      CIMTinRenderer renderer = lasDatasetLayer.CreateRenderer(lasPointsClassBreaksRendererDef);
      if (lasDatasetLayer.CanSetRenderer(renderer, SurfaceRendererTarget.Points))
        lasDatasetLayer.SetRenderer(renderer, SurfaceRendererTarget.Points);
    }
