TIA I've also seen John Peltier's example, but it only gives a qualitative explanation of the problem...Ok, he says, yes, excel's smoothing curve is a belzier spline, but I still can't understand ho to interpolate my data qirh a belzier's curve in such a way... :-( |

Thank you, I've already seen it just yesterday, but I think the example file
is only a "demonstration"...and I need a function or (better) a macro that makes possible the interpolation of XY data set with bezier's curve...:-( (I'm a newbie in VBA and still don't know how to build a routine that could make it...) |

The macro functions are in the file (Tools|Macro|Visual Basic Editor).
The example is an example of how to use them, that also demonstrates the point that they match what Excel's chart smoother does.
