Need to use a classbreakrenderer, but for one of the class breaks of numbers 1-1, need to use uniquevaluerenderer for that class.
What is the best way to do this?
Actually need to have one of those classbreak renderer be not set to just a single symbol, but to another set of renderers- i.e. uniquerenderers with its own different sets of symbols.
Thanks.
You can have a classbreakrenderer that only has a single value. Using the classbreakrenderer sample, set one state_fips to its own color. (This code will only show some states and counties since it's retrieving only the first 1000). Indiana (state_fips = 18) will be colored yellow.
