Struct PriceTransform 

pub struct PriceTransform {
    pub mode: PriceScaleMode,
    pub base: f64,
}

How one series’ prices become scale units.

Percentage and indexed modes are relative to base, the series’ first visible close; normal and logarithmic modes ignore it.

Fields

mode: PriceScaleMode

Scale mode

base: f64

Reference price for the percentage and indexed modes

Implementations

impl PriceTransform

pub fn to_scale(&self, price: f64) -> f64

Converts a price to scale units.

Logarithmic maps non-positive prices to negative infinity, which PriceMap places far below the pane.

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

Converts scale units back to a price.
