This is an archive related to a previous version of Esri Maps for IBM Cognos. If you need the current version go to http://doc.arcgis.com/en/maps-for-cognos/.
In Esri Maps for IBM Cognos, layers are drawn on the map using a style configured by the report author. The style currently applied to a layer is shown in the Contents pane when you expand the layer by pressing the plus sign (+).
A layer can have multiple styles configured for it. Different styles allow the data to be displayed based on different measures or attributes. If multiple styles were configured, you can choose a different preconfigured style to change how the layer is drawn.
Whether a layer has multiple preconfigured styles or a single preconfigured style, you can change individual symbols or colors, or modify the grouping method for grouped styles based on number ranges.
Styles can be changed for layers created from IBM Cognos data or for feature service layers from ArcGIS.
For more information, see Grouping methods.
The map automatically updates to reflect the style changes you made. Any style changes you make are saved during the session. When you close and later reopen the map, the style applied by the report author is displayed and your changes are lost.
