Struct Binning 

pub struct Binning {
    pub scale: Scale,
    /* private fields */
}

Equal-width bins on a scale, keyed by integers from 0 at 0. The log scale is the Axis every histogram reads values on: ln(shift + x), the shift 1 for counts and smaller for values mostly below 1.

Fields

scale: Scale

Implementations

impl Binning

pub fn new(scale: Scale, max: f64, integer: bool) -> Self

Bins spanning 0..=max. Whole counts (integer) get linear bins at least one count wide, so no bin falls between two integers. The log scale shifts by 1 for whole counts or a max of 20 and over, else by a thousandth of max; Binned::new shifts as the data says.

pub fn with_width(scale: Scale, width: f64) -> Self

Bins of an explicit width on the scaled axis. On the linear scale with width 1, bin k holds exactly the value k, so a histogram of bin indices draws one bar per category.

pub fn key(&self, x: f64) -> i32

pub fn lower_edge(&self, k: i32) -> usize

Smallest whole count in bin k or above: the cutoff that drops every bin left of k.
