Example

To generate bubble charts from a data source, do the following.

  1. Create a BubbleChartDataAdapter object and assign it to the VectorLayer.Data property.
  2. Bind a data source to the DataSourceAdapterBase.DataSource property of the object.
  3. Specify mappings to assign data fields to bubble properties. To do this, specify the MapPointMappingInfoBase.Latitude, MapPointMappingInfoBase.Longitude and MapBubbleMappingInfo.Value properties of the MapBubbleMappingInfo object assigned to the BubbleChartDataAdapter.Mappings property.
  4. Specify settings which are used to generate map bubble charts. To do this, specify the MapBubbleSettings object’s properties. This object can be accessed using the BubbleChartDataAdapter.BubbleSettings property of the adapter.
