Parameters
----------
fluxes : numpy array
The data, stored in a niter by (npar + 2) matrix, where
each row is an iteration, the first column is the flux for
that row, the next npar columns are the parameter values,
and the last column indicates whether the row was clipped
(1) or not (0).
bins : int
The number of bins to split the flux data into.
