Struct Ramp

Source

pub struct Ramp { /* private fields */ }

Expand description

A colour ramp sampled at t ∈ 0..=1. Built from theme colours so it follows the active palette.

Implementations§

Source §

impl Ramp

Source

pub fn sequential(th: &Theme) -> Self

Sequential low→high ramp: a dim theme ground → accent → glow. Good for magnitudes (heatmaps, treemap weights).

Source

pub fn diverging(th: &Theme) -> Self

Diverging ramp: accent (low) → a neutral mid (theme text_dim) → glow (high). Good for signed values around a midpoint.

Source

pub fn at(&self, t: f32) -> Color32

Sample the ramp at t, clamped to 0..=1.

Source

pub fn stops(&self) -> [Color32; 3]

The control stops, for a legend gradient.
