Have a uniquerenderer inside classbreakrenderer?

EdwardSohn2 — Mon, 01 Dec 2014 02:09:47 GMT

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?

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.

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.
