Hello,

I would need to create a column with the formula -dy/dx, smoothed via adjacent-averaging method. Is there any way to achieve this that wouldn't require me to add 3 extra columns each time (one for dy/dx, a second one for changing previous column sign and a third one for smoothing)? My worksheets already contain multiple columns and I would like to avoid creating any unnecessary ones.

I am using differentiate function since derivative function is no longer recommended, but the options are very limited.

Thank you.

Hi,

can you set script in Before Formula Scripts? I used LT function and Smooth X-function. see if it works.


Dataset dsC;
dsC = derivativexy(col(A), col(B));
smooth -r 2 method:=aav npts:=9 iy:= dsC oy:= dsC;
