Struct HeatmapPlot 

pub struct HeatmapPlot<'a> { /* private fields */ }

Builder for heatmap plots with extensive customization options

Implementations

impl<'a> HeatmapPlot<'a>

pub fn new(label: &'a str, values: &'a [f64], rows: usize, cols: usize) -> Self

Create a new heatmap plot with the given label and data

Arguments

• label - The label for the heatmap
• values - The data values in row-major order (unless ColMajor flag is set)
• rows - Number of rows in the data
• cols - Number of columns in the data

pub fn with_scale(self, min: f64, max: f64) -> Self

Set the color scale range (min, max) If both are 0.0, auto-scaling will be used

pub fn with_label_format(self, fmt: Option<&'a str>) -> Self

Set the label format for values (e.g., “%.2f”, “%.1e”) Set to None to disable labels

pub fn with_bounds(self, min_x: f64, min_y: f64, max_x: f64, max_y: f64) -> Self

Set the drawing area bounds in plot coordinates

pub fn with_bounds_points(self, min: ImPlotPoint, max: ImPlotPoint) -> Self

Set the drawing area bounds using ImPlotPoint

pub fn with_flags(self, flags: HeatmapFlags) -> Self

Set heatmap flags for customization

pub fn with_item_flags(self, flags: ItemFlags) -> Self

Set common item flags for this plot item (applies to all plot types)

pub fn column_major(self) -> Self

Use column-major data ordering instead of row-major

pub fn validate(&self) -> Result<(), PlotError>

Validate the plot data
