Enum Normalization 

pub enum Normalization {
    Linear {
        min: f64,
        max: f64,
    },
    Symmetric {
        center: f64,
        half: f64,
    },
}

Maps a data value onto the [0, 1] input of a GradientColorMap.

Variants

Linear

Linear map: min -> 0, max -> 1.

Fields

min: f64

Value mapped to 0.

max: f64

Value mapped to 1.

Symmetric

Symmetric (diverging) map centered on center: center -> 0.5, and center ± half -> 0 / 1. Ideal for values around zero.

Fields

center: f64

The value placed at the midpoint (0.5).

half: f64

Half-range: center + half maps to 1, center - half to 0.

Implementations

impl Normalization

pub fn t(&self, v: f64) -> f64

Normalize v to [0, 1] (clamped). Non-finite v returns NaN, which callers can treat as “no data”.

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

Inverse of Normalization::t: the data value at position t in [0, 1]. Used to label a colorbar.

Trait Implementations

impl Clone for Normalization

fn clone(&self) -> Normalization

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Normalization

impl Debug for Normalization

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

Formats the value using the given formatter.

impl PartialEq for Normalization

fn eq(&self, other: &Normalization) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
