Struct ScalePoint 

pub struct ScalePoint<T> { /* private fields */ }

Point scale maps discrete domain values to continuous range positions.

Points are evenly distributed across the range, with the first and last points aligned to the range boundaries.

Implementations

impl<T> ScalePoint<T>

where T: PartialEq,

pub fn new(domain: Vec<T>, range: Vec<f32>) -> Self

Creates a new point scale with the given domain and range.

Examples

let scale = ScalePoint::new(vec![1, 2, 3], vec![0., 100.]);
assert_eq!(scale.tick(&1), Some(0.));
assert_eq!(scale.tick(&2), Some(50.));
assert_eq!(scale.tick(&3), Some(100.));

Trait Implementations

impl<T: Clone> Clone for ScalePoint<T>

fn clone(&self) -> ScalePoint<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Scale<T> for ScalePoint<T>

where T: PartialEq,

fn tick(&self, value: &T) -> Option<f32>

Get the tick of the scale.

fn least_index(&self, tick: f32) -> usize

Get the least index of the scale.

fn least_index_with_domain(&self, _tick: f32, _domain: &[T]) -> (usize, f32)

Get the least index of the scale with the domain.
