The problem is, that splines as used in OOo (old and new way) are build in such
a way that the second-order derivative is continuous. I don't know Excels way,
but from seen curve I would say they have at least first-order derivative
continuous. Therefore you cannot use splines to smooth a curve with corners. Up
to now you have to define different data series from corner to corner. In
physics you will have such corners for example in a graph of a hysteresis.
