if no data It will be white
if A bigger than B it will be yellow otherwise make red.
But I tried to create materilas,and 3 layer with different in this material.LAYERS :bottom white than yellow and top red.
this work for one city,but when I tried this visual logics to another city it confused and not working.
How can I fix this or any easier way to do it?
