Style polygons
In this topic
When you add data from your business system to a map, Esri Maps for IBM Cognos creates a layer and displays the data using a default style. These layers, and certain layers added from ArcGIS, can be styled using different symbols, colors, and grouping.
One way to style a polygon layer is using a single color to represent all of the features in the layer. Another way is to divide the polygon features into groups and style each group with a different color. For example, you might want to use different colors to denote sales territories classified by revenue range.
As you modify the style options for your layer, the map automatically updates to reflect your settings.
For more information on styling layers, see Feature display and style.
