A dot density renderer.
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
Description
Use this renderer to create dot density maps (a.k.a. dot maps). The DotDensityRenderer represents quantitative data by drawing randomly placed dots (actually any type of marker symbol) inside polygon features. To use, you must also have a DotDensityFillSymbol.
Supported Platforms
Windows, Solaris, Linux
Interfaces
| Interfaces | Description |
|---|---|
| IDataExclusion | Provides access to members that control the exclusion of data values from a renderer. |
| IDataExclusion2 | Provides access to members that control the exclusion of data values from a renderer. |
| IDotDensityRenderer | Provides access to members that control the drawing of varying densities of dots within polygon features to represent different quantities. |
| IDotDensityRenderer2 | Provides access to members that control the drawing of varying densities of dots within polygon features to represent different quantities. |
| IDotDensityUIRenderer | Provides access to members that work with additional renderer properties which appear on the user interface. |
| IExportSupport | Provides access to export support members. |
| IFeatureRenderer | Provides access to members that control functionality common to all feature renderers. |
| ILegendInfo | Provides access to members that control legend information provided by a renderer. |
| IPersist | Defines the single method GetClassID, which is designed to supply the CLSID of an object that can be stored persistently in the system. IPersist is the base interface for three other interfaces: IPersistStorage, IPersistStream, and IPersistFile. |
| IPersistStream (esriSystem) | |
| IRendererFields | Provides access to members that work with the list of fields for renderers that use multiple value fields. |
