Re: smooth equation

Well, My plot are magnetic field measurements in complex situation
(lot of conductors and so on). Then the variation is really smooth but
the shapes can ve very different from one plot to the other (depending
on the component of the vector also).
The tries I have done with sbezier were quite good.

Hopefully, for me the graphics with the initial data are what I look
at.
The difference with sbezier is to show a gain or a losse to "not
involved people".
The smoothing will be then checked each times before.
