How to: Change Map Legends, Color Scale, and Associated Rules (Report Builder 3.0 and SSRS)

A map can contain map legends, a color scale, and a distance scale. These parts of a map help users interpret the data visualization on the map.

Legends include the following parts of a map:

  • Map legend   Displays a guide to help interpret the analytical data that varies the display of a map elements on a map layer. A map can have multiple legends. For each map layer, you A specify which legend to use. A legend can provide a guide to more than one map layer.

  • Color scale   Displays a guide to help interpret colors on the map. A map has one color scale. Multiple layers can provide the data for the color scale.

  • Distance scale   Displays a guide to help interpret the scale of the map. A map has one distance scale. The current map viewport zoom value determines the distance scale.

You can create and modify report definitions (.rdl) in Report Builder 3.0 and in Report Designer in Business Intelligence Development Studio. Each authoring environment provides different ways to create, open, and save reports and related items.
