"WebOct 29, 2024 · Actually no it is not so simple. I need to think a bit more and come back with additional information. A simple interpolation will not do what I want since the X,Y values are actually a 2D shape that corresponds to certain force values for every X,Y pair. Means, that the force values needs to be interpolated while the X,Y pair changes. " - Polynomial interpolation in excel
