Struct MissingnessHeatmap 

pub struct MissingnessHeatmap { /* private fields */ }

A present/absent map: one column per variable, observations down the rows.

Implementations

impl MissingnessHeatmap

pub fn from_columns( columns: &[Vec<Option<f64>>], labels: Vec<String>, ) -> Result<Self, StatsError>

Build from columns of Option<f64> (one column per variable; None = missing). Columns may differ in length; shorter columns are treated as missing past their end. labels names the variables.

Errors

• StatsError::EmptyInput if there are no columns.
• StatsError::LengthMismatch if labels and columns differ in count.

pub fn present_color(self, color: RGBColor) -> Self

Set the color used for present values.

pub fn missing_color(self, color: RGBColor) -> Self

Set the color used for missing values.

pub fn show_percent(self, on: bool) -> Self

Toggle the per-column missing-percentage labels.

pub fn title(self, title: impl Into<String>) -> Self

Set a title drawn above the grid.

pub fn draw<DB: DrawingBackend>( &self, area: &DrawingArea<DB, Shift>, ) -> Result<(), Box<dyn Error>>

where DB::ErrorType: 'static,

Render the heatmap onto area.
