Struct ScaleBand 

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

Implementations

impl<T> ScaleBand<T>

pub fn new(domain: impl IntoIterator<Item = T>, range: [f32; 2]) -> ScaleBand<T>

where T: Eq + Hash,

Lay the distinct values of domain out as bands across range, from its lower end in domain order.

pub fn band_width(&self) -> f32

The width of a band: the range divided among the bands, less the inner padding, and no wider than Self::max_band_width when set.

pub fn max_band_width(self, width: f32) -> ScaleBand<T>

Cap the band width at width, so a few bands in a wide range stay narrow; a band still starts where it would uncapped. Unset by default.

pub fn step(&self) -> f32

The distance between the starts of two adjacent bands: the band width plus the inner padding. The whole range for a single band.

pub fn band_count(self, count: usize) -> ScaleBand<T>

Lay the range out for count bands, the domain taking the leading ones in order and the rest staying empty. A count below the domain’s length has no effect.

pub fn padding_inner(self, padding_inner: f32) -> ScaleBand<T>

Set the padding inner of the band.

pub fn padding_outer(self, padding_outer: f32) -> ScaleBand<T>

Set the padding outer of the band.

Trait Implementations

impl<T> Clone for ScaleBand<T>

where T: Clone,

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Scale<T> for ScaleBand<T>

where T: Eq + Hash,

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

Get the tick of the scale.

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

The index of the domain value whose position is nearest tick; 0 for an empty domain or a scale without discrete positions.
