Lag series operator with lag -1

Dear all,

I would like to suggest a new feature to the "lag series" operator of the series extension. Currently this operator lags the selected attribute according to the specified parameter. However, the parameter has to be >= 1. So I was wondering why this is limited in that way. I would come handy if this operator could also lag negative values -> the other direction.

Best regards

Sachs

    Hey, this is a great idea. Have you thought about adding it to ourIdea forum? Our Developers scan that regularily for ideas instead of digging through there.

    Hi@suleymansahal,

    I see where you are comming from. A workaround would be to sort the data set the other way around, lag it, and sort it again.

    Best,

    Hi Martin,

    Thank you for the solution. I guess I just have to create new id attribute if the present one is not in correct order.
