This map has an incredible amount of flexibility as is can use the information from any field in the mapping table as the basis for coloring counties on the map. For a map to be setup, a user has to know what high and low thresholds they want to use for each item in the legend and the color any county meeting those criteria should be. These Categories must be distinct; a county can only fall in one category.
Use of optional parameters will override the existing default parameters of the map. A user can use this to modify the function of an existing map rather than requesting a new map.
