I do not think that will help me. What I want is to have the user have different color/size of labels of the feature layer based on the class breaks. An example is this
If a county in the USA has a population less than 50,000 then make the label color red and 8pt font, else color the label from the feature layer green and make 10 pt. Again the color/size will come from the end user. I just need to find a way to change the feature layers label based on the end users input.
