Defining Symbols

How to:

Symbols are used to display features or entities on a map. For point features, use Marker symbols. For line features, use Line symbols. For polygon features, use Fill symbols. Other symbols that can be created are Callout and Text symbols to display contextual text.

The following image shows the XML definition file (esriconfig_new.xml) being edited in the ESRI Configuration Utility. The esriconfig_new.xml file is used by the Retail Predictives sample application. In this image, the Symbols tab is selected.

The Retail Predictives sample application uses the following symbols. The Java Class being used by each symbol is also listed.
