Change a layer's style

In this topic

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 floating legend (if it has been enabled by the report author) and in the Contents pane when you expand the layer.

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.

Display the legend

  1. Do one of the following to display the legend for a layer:
    • Open the Contents pane and click the arrow beside the layer to expand it.
    • If it is enabled by the report author, click the Legend button Legend to open the legend in a floating window. Choose a layer from the drop-down menu.

Change the style

  1. If multiple styles were configured for the layer, choose the style you want from the Styles drop-down menu.
  2. If you want to modify a symbol or shape used in the style, click the symbol or shape and do one of the following:
    • Point layers can be styled using icon or shape symbols. If icons were used for styling, choose a different icon from the drop-down menu. If shapes were used, choose a new color.
    • For lines and polygons, choose a new color for the shape.
  3. If you want to change the grouping method for a grouped style based on number ranges, choose a classification method from the drop-down menu.

    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.


For grouped styles, you can easily change the visibility of individual groups. See Change a layer's visibility.
