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... :-(

See Brian Murphy's example at

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.

thank you very much (for your patience above all), now I can try to solve my
problem looking that macro...
