Labels and Legends
Maps need text such as labels and legends to deliver the message of the map.
Labels describe the data in the feature table. They can be customized in many ways, including their visibility, position, style, and content. Themes that change the style and content can be applied to label layers. Use MI SQL expressions to generate custom label strings and rules.
Legends are cartographic elements that describe the features in a coded manner. For example, the legend may describe the boundaries as school districts, the lines as a power line network, or points as corporate office locations. Legends also contain a title to describe collectively what the map represents.
Legends in Spectrumâ„¢ Technology Platform are generated on the fly when a map is requested, and based on the defined themes and styles of the map's layers.
