What are the legends and scales in Map Preview for?
Legends help a user interpret the data that is displayed on a map. A map provides a color range, a distance scale, and a legend. • Color range. The color range displays a color bar with a scale that provides a guide to the data intervals that are determined by the report processor based on the rules that you specify for the layer. • Distance scale. The distance scale provides a guide to the distance units on the map. Distance units are determined automatically based on the map projection and zoom level. • Legend. The legend provides a guide to help interpret the meaning of colors, sizes, and marker types on a map. By default, all the rules for all the layers display data intervals in the first legend. You can customize this legend and add legends after you add the map to the report.
