Trait ndarray_stats::histogram::strategies::BinsBuildingStrategy

pub trait BinsBuildingStrategy {
    type Elem: Ord;

    fn from_array<S>(array: &ArrayBase<S, Ix1>) -> Self
    where
        S: Data<Elem = Self::Elem>;
    fn build(&self) -> Bins<Self::Elem>;
    fn n_bins(&self) -> usize;
}

A trait implemented by all strategies to build Bins with parameters inferred from observations.

A BinsBuildingStrategy is required by GridBuilder to know how to build a Grid’s projections on the coordinate axes.

Required Associated Types

type Elem: Ord

Required Methods

fn from_array<S>(array: &ArrayBase<S, Ix1>) -> Selfwhere
    S: Data<Elem = Self::Elem>,

Given some observations in a 1-dimensional array it returns a BinsBuildingStrategy that has learned the required parameter to build a collection of Bins.

fn build(&self) -> Bins<Self::Elem>

Returns a Bins instance, built accordingly to the parameters inferred from observations in from_array.

fn n_bins(&self) -> usize

Returns the optimal number of bins, according to the parameters inferred from observations in from_array.
