Struct HeatmapView 

pub struct HeatmapView {
    pub title: String,
    pub rows: usize,
    pub cols: usize,
    pub data: Vec<f64>,
    pub row_labels: Vec<String>,
    pub col_labels: Vec<String>,
    pub diverging: bool,
}

A dense matrix in row-major order with optional axis labels.

Fields

title: String

rows: usize

cols: usize

data: Vec<f64>

Row-major: data[r * cols + c].

row_labels: Vec<String>

col_labels: Vec<String>

diverging: bool

Use the diverging ramp (around a midpoint) instead of sequential.

Implementations

impl HeatmapView

pub fn new( title: impl Into<String>, rows: usize, cols: usize, data: Vec<f64>, ) -> Self

pub fn with_labels(self, rows: Vec<String>, cols: Vec<String>) -> Self

pub fn diverging(self) -> Self

pub fn get(&self, row: usize, col: usize) -> Option<f64>

Value at (row, col), or None if out of bounds / ragged data.

pub fn value_range(&self) -> Option<(f64, f64)>

(min, max) over the finite cells.

Trait Implementations

impl Facet for HeatmapView

fn title(&self) -> &str

fn caps(&self) -> FacetCaps

What this facet can do. Override to opt into capabilities.

fn copy(&mut self) -> Option<String>

Clipboard hooks — see clipboard.rs. Defaults: nothing to give/take. Returns the text to place on the clipboard (None = nothing copyable now).

fn ui(&mut self, ui: &mut Ui)

fn state_json(&self) -> Value

fn scale(&self) -> f32

Current uniform scale (1.0 = native). Override if caps().scalable.

fn set_scale(&mut self, _scale: f32)

Set the uniform scale; clamp internally. Default no-op (not scalable).

fn selection_json(&self) -> Value

The current selection as JSON (also folded into state_json by convention). Null when nothing/none selectable.

fn cut(&mut self) -> Option<String>

Like copy, but also removes the selection. Default delegates to copy.

fn paste(&mut self, _text: &str) -> bool

Accept pasted text. Returns true if consumed.

fn as_any_mut(&mut self) -> Option<&mut (dyn Any + 'static)>

Optional downcast handle for hosts that need typed access to a specific facet living inside a FacetDeck (e.g. a robot-UI driver clicking an app-level control that must forward to a concrete component’s own API). Defaulted to None so no existing facet has to change; a component opts in by returning Some(self).
