curve fitting?

[wen <wendelinhw gmx de>]

Hi,
is there a possibility to do curve-fitting within  (or outside) a
gnumeric-chart? I can't find that function nor any information on the
web (and the mails in this list i found about that topic are at least 3
years old).


What i mean:
I plotted data points in a chart and would like gnumeric to plot -for
example- the polynomial of second order that fits best (and to output
the parameters of that polynom).

I am using gnumeric 1.5.1.

Thanks for your help and this great application,
wen
