CIMHeatMapRenderer Class
In This Topic
Represents a heat map renderer.
The Heat Map Renderer draws point features as a continuous /// color gradient representing the density of the points. The resulting /// density surface represents the physical proximity between points, /// optionally weighted by a specified attribute value. The displayed /// raster surface is dynamic and morphs according to the zoom level /// and updates if the source point features are edited.

Example
Create a Heatmap Renderer
string colorBrewerSchemesName = "ArcGIS Colors"; StyleProjectItem style = Project.Current.GetItems<StyleProjectItem>().First(s => s.Name == colorBrewerSchemesName); string colorRampName = "Heat Map 4 - Semitransparent"; IList<ColorRampStyleItem> colorRampList = await QueuedTask.Run(() => { return style.SearchColorRamps(colorRampName); }); ColorRampStyleItem colorRamp = colorRampList[0]; await QueuedTask.Run(() => { //defining a heatmap renderer that uses values from Population field as the weights HeatMapRendererDefinition heatMapDef = new HeatMapRendererDefinition() { Radius = 20, WeightField = "Population", ColorRamp = colorRamp.ColorRamp, RendereringQuality = 8, UpperLabel = "High Density", LowerLabel = "Low Density" }; FeatureLayer flyr = MapView.Active.Map.Layers[0] as FeatureLayer; CIMHeatMapRenderer heatMapRndr = flyr.CreateRenderer(heatMapDef) as CIMHeatMapRenderer; flyr.SetRenderer(heatMapRndr); });
