Hi, everyone.
I am stucked. I need to create an attribute with the difference betweem a value from another attribute of the same row and the value of that same attribute from the row just above.
In Excel, it would be like, on the colum "=[@[lanData_time]]-A(numer of the row just above)". Anyone could help me?
Thanks!

I am not completely sure, but do you want to create the differentation of an Attribute: a_i - a_i-1. Try out the Differentiate operator from the time series operators. Deselect 'overwrite attributes' to create a new attribute containing the differentiated values.
