Enum BinRule 

pub enum BinRule {
    Count(usize),
    Width(f64),
    Sturges,
    FreedmanDiaconis,
    Scott,
}

How to choose the number/width of histogram bins.

Variants

Count(usize)

A fixed number of equal-width bins.

Width(f64)

A fixed bin width (bin count derived from the data range).

Sturges

Sturges’ rule: ceil(log2(n)) + 1.

FreedmanDiaconis

Freedman–Diaconis rule: width = 2 * IQR * n^(-1/3).

Scott

Scott’s rule: width = 3.49 * std * n^(-1/3).
