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 updates if the source point features are edited.

Example
Create a Heatmap Renderer
{
string colorBrewerSchemesName = "ArcGIS Colors";
//Get the style project item that contains the color ramps
//Refer to the Initialize region for an example of how to get a style item
//and the color ramp from it.
//Note: Run within a QueuedTask
//defining a heatmap renderer that uses values from Population field as the weights
HeatMapRendererDefinition heatMapDef = new HeatMapRendererDefinition()
{
Radius = 20,
WeightField = "Population",
ColorRamp = colorRamp,
RendereringQuality = 8,
UpperLabel = "High Density",
LowerLabel = "Low Density"
};
CIMHeatMapRenderer heatMapRndr = featureLayer.CreateRenderer(heatMapDef) as CIMHeatMapRenderer;
featureLayer.SetRenderer(heatMapRndr);
}
