how to use power law fit for my graph so that i can find a,n from the equation of the power law i.e. y = a * x(exp)n

[kaps]

hi,
i am trying to smoothen a graph. i want to try power law fit of the form y = a * x (exp)n and find the corresponding a & n from the fit.

What does it mean "power fit"? Do you want use polynomial fit? This vi founds in Mathematics\Curve Fitting.

kaps,

You may also want to try the Levenberg Marquardt.vi in Functions>Mathemeatics>Curve Fitting as well as the polynomial fit as suggested by nchernin.
