Struct ScaleTime 

pub struct ScaleTime { /* private fields */ }

Maps a temporal domain (NaiveDateTime) to a continuous range via linear interpolation on timestamps. Equivalent to D3’s scaleUtc().

Implementations

impl ScaleTime

pub fn new(domain: (NaiveDateTime, NaiveDateTime), range: (f64, f64)) -> Self

Create a new time scale with the given domain and range.

pub fn map(&self, value: &NaiveDateTime) -> f64

Map a datetime to a range value via linear interpolation on timestamps.

pub fn invert(&self, value: f64) -> NaiveDateTime

Inverse: range value back to NaiveDateTime.

pub fn ticks(&self, count: usize) -> Vec<NaiveDateTime>

Generate nice time ticks. Strategy: convert to timestamps, use linear tick algorithm on the timestamp space, then convert back to NaiveDateTime.

pub fn domain(&self) -> (NaiveDateTime, NaiveDateTime)

Get the domain extent.

pub fn range(&self) -> (f64, f64)

Get the range extent.
