calculating attributes with formulas by layer

JSL Global Mapper UserTrusted User

Hi, I'm trying to use the formula calculation option when creating attributes. I have more than one layer, and for each layer, I'd like to find the maximum value of a particular attribute. I select all the layers, open the calculate attributes panel, and input @max(ATTR) . However, it then calculates the maximum value of the set of layers, when what I want is each individual layer to get its own maximum value. Is there any way to achieve what I'm trying to do, or do I have to do a separate formula calculation for each layer?@Max06

    (Ignore that last blue @max06, I don't know how that got there)
