Configuration

Implementations

impl HeatmapStrip

pub fn new() -> Self

Create a new empty heatmap strip

pub fn with_config(config: HeatmapStripConfig) -> Self

Create with custom configuration

pub fn set_data(&mut self, data: impl IntoIterator<Item = (usize, f64, f64)>)

Set the cells from delta/volume data, sorting them by bar index.

pub fn add_cell(&mut self, bar_idx: usize, delta: f64, volume: f64)

Add a single cell, keeping the cells ordered by bar index. Appending in bar-index order takes amortized constant time.

pub fn cells(&self) -> impl ExactSizeIterator<Item = HeatmapCell> + '_

Cells in bar-index order, with intensities normalized against all held deltas.

pub fn clear(&mut self)

Clear all cells and their normalization maxima.

pub fn render( &self, ui: &mut Ui, strip_rect: Rect, visible_range: (usize, usize), bar_width: f32, x: impl Fn(usize) -> f32, )

Render the heatmap strip

Arguments

• ui - The egui UI context
• strip_rect - The rectangle where the strip should be drawn
• visible_range - The inclusive visible bar index range (start, end)
• bar_width - Spacing between bar centres in logical points
• x - The screen x coordinate of each absolute bar index’s centre
