accumulation

[#1]

I have 2 feilds named year, sales. If i select a year then i should get the accumulation of the sum of the sales of the previous 5 years dynamically? Example: if i slect year 2005 i should get the sales from 2000 to 2005 and the sales should be accumulated.

Accumulation in a text object? Chart?? Do you have a sample??

sum({<year={">=$(=max(year)-5)<=$(=max(year))"}>}sales)
