in the picture you can see an attribute table of an heat meter. The number of the heat meter is 11250423. The heat status is given monthly. Now I want to make an expression to get the consumption of every month.
in theory I have to do sth like this:
y_(i+1)-y_(i) = consumption
Month 1 (january): y_(1+1)-y_(1) = consumption of January
Month 2 (feb): y_(2+1)-y_(2) = consumption of February
Month 12 (dec): y_(12+1)-y_(12) = consumption of December
does anybody know, how to write an expression in arcgis? I want to make a new field to calculate.
Thanks for helping.
