I am working with ArcMap 10.4 and have some issues. I'm making a Floodmap based for Europe and want to color the shapes related to the total amount of floods in every polygon. For example I have Czech Republic where 3 of the 8 shapes has 5 floods as a total amount in the attribute table. Is it possible to give these 3 shapes (and all the other ones with 5 floods) automatically the same (orange) color?
its possible to give polygons styles based on attributes. Right click on your layer in the table of contents. Choose properties, then the Symbology tab. If you choose Categories, then unique values you can choose a style based on the contents of a field that you choose.
Do the different layers have the same attributes? If so you can import symbology between them:
