I need to make around 20 Choropleth maps. However as they will be compared against one another, i have found the maxim and minimum value for the entire data set and am trying to classify using those values.
However ArcMap will not let me enter a minimum value of 400 as the data for that specific map has it's minimum value at 600. Is there a way of changing this and creating a classification where by i can enter a min and max value that is greater than the data being used?
I have also encountered this problem and I am surprised to see that the latest version, 10.3, does not address this. I think Antonio has a good work around. I have done the same in the past, however, it is not ideal in a normal work flow.
