I am displaying three different layers on a map, essentially three separate habitat types. Each have their own colour. In cases, 2 or 3 of the layers overlap in part (essentially showing where habitat types overlap). How can I display this overlap in the legend?
If you have more time to play with data, you can intersect only two layers a time just to identify and symbolise intersections of each shapefile (1 and 2, 1 and 3, 2 and 3)
