I want to define classes according to the proportion between two attributes of the feature. How to do this? For example: feature has two attributes 'PopulationOver65' and 'PopulationTotal'. They are both numbers. I want the color of this feature: green if PopulationOver65/PopulationTotal <10%, yellow if 10% -30%, red if 30%.
Anyway to do this?
