Perhaps it would be clearer to see what you mean with a code example.

If you want to plot a distribution implemented in Commons Math, you'd
call one the methods defined in the "RealDistribution" interface
(e.g. "density(double x)").

But maybe that the functionality which you are looking for is defined
in package "org.apache.commons.math3.stat.inference".

If you need to fit data to a model (e.g. find the parameters of an
assumed distribution), it is perhaps the least-squares fitting which
you are looking for.  For a univariate function, there is a utility
implemented as "org.apache.commons.math3.fitting.SimpleCurveFitter".


HTH,
Gilles
