Struct PriceAxis 

pub struct PriceAxis {
    pub row_step: PriceStep,
    pub precision: MinTicksize,
}

Fields

row_step: PriceStep

Effective tick size the grid rows are aligned to.

precision: MinTicksize

Precision used to format label values.

Implementations

impl PriceAxis

pub fn new(row_step: PriceStep, precision: Option<MinTicksize>) -> Self

Bundle a row step with a label precision. precision falls back to the precision implied by row_step when not given.

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

Row-aligned ticks over a range; empty when no coarser “nice” grid fits.

pub fn ticks_from_row(&self, lowest: f64, highest: f64) -> YTicks

A dense tick grid at exactly the row step (fallback for charts that always want to show rows).

pub fn format_units(&self, units: i64) -> String

Format a row value (atomic units) at this axis’s precision.

pub fn format(&self, price: Price) -> String

Format a price at this axis’s precision.

pub fn y_to_price(&self, y: f32, cell_height: f32, min: Price) -> Price

Convert a canvas y position (pixels) to a price, exact to within one atomic unit (1e-11). Only the pixel geometry (y, cell_height) is f32; the base price and row step are exact atomic-unit values, so the offset arithmetic runs in f64 and is quantized once at the end.
