Hello, I work with a habitats polygon layer that includes about 100 habitat types. Most of the maps I produce with it will only have 5-10 of these habitats in the mapping area. However when I make the legend all 100 are included. At present I am manually making the legend for each map, which of course is time consuming. Is there a way to include only the habitats that are included in the map in the key, and not all those within the shapefile/feature class? Thanks!
