Enum YAxisScale 

pub enum YAxisScale {
    Price {
        row_step: PriceStep,
    },
    Linear,
    Percent,
}

The family of Y-axis scales.

A scale owns both how tick values are chosen and how values map to normalized positions.

Variants

Price

Row-aligned price scale: grid steps are snapped to multiples of row_step so every label lands on a real price row. Values are exact atomic units; positions are linear in price.

Fields

row_step: PriceStep

Linear

Plain continuous linear scale (indicator values, etc.). Steps are “nice”; positions are linear.

Percent

Percentage scale (comparison chart). Shares the linear grid with YAxisScale::Linear for now, kept distinct so percent-specific step or formatting policy has a home.

Implementations

impl YAxisScale

pub fn ticks(&self, lowest: f64, highest: f64, labels_can_fit: i32) -> YTicks

Generate the ticks for a visible range. Returns an empty list when the range is empty or no grid fits (callers decide their fallback).

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

Performs copy-assignment from source.

impl Copy for YAxisScale

impl Debug for YAxisScale

fn fmt(&self, f: &mut Formatter<'_>) -> Result
