Back Transformation for Legendre Polynomials

[WARGREYMONKKTL]

some body who can explain for me the Legndre polynomials

What do you want to know and what do you already know about them

Surely, nobody will be willing to type the whole theory behind them so be more specific please

A set of polynomials dependent on continuous variable x and integers m (and sometimes n) which have useful orthogonality and spanning properties.

Known to have useful solutions when dealing with spherical coordinates and potentials. Want more info? There's a fantastic website I know called Google. It'll find anything for you ;)

Legendre Polynomials

I need some help. I fitted a 7th order legendre polynomial and got the L0 to L7 coefficients for different classes. How can I get a back transformation in order to plot each class using the estimated coefficients?
Thanks to anybody.
Roberto.
