Is there an operator to calculate the difference with its previous value?

If the attribute has these values: [ 3, 7, 9, 6, 11 ]
Can we generate an attribute consisting of the differences of the two values? 
Like:   [ 4, 2 -3, 5]?

    Hi @c_chee, 
    a quick way is using the Lag operator for Time series. with this operator you can create a new attribute with a Lag and then you can calculate the diffenrence between the attributes. 
    Other option is using the loop operators. 

    Best.

    Hi Ceaperez,

    Thanks for the answer. I'll have a look soon, but I'm sure it'll work.
