Struct StatTreemap 

pub struct StatTreemap {
    pub aspect: f64,
    pub group_padding: f64,
}

Squarified treemap stat behind GeomTreemap.

Fields

aspect: f64

Layout width / height (match the panel’s so tiles come out square).

group_padding: f64

Inset of each group’s tiles inside the group rectangle, in layout units.

Trait Implementations

impl Clone for StatTreemap

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StatTreemap

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for StatTreemap

fn default() -> Self

Returns the “default value” for a type.

impl Stat for StatTreemap

fn panelwise(&self) -> bool

Tiles share one rectangle: every row of the panel is laid out at once.

fn compute_group(&self, data: &DataFrame, _scales: &ScaleSet) -> DataFrame

Transform data for a single group.

fn required_aes(&self) -> Vec<Aesthetic>

Required aesthetics this stat needs.

fn name(&self) -> &str

Name for debug/display.

fn default_aes(&self) -> Aes

Default aesthetic mappings this stat produces.

fn validate(&self, _warnings: &mut Vec<String>)

Validate the stat’s own fixed configuration (not the data) and push a human-readable warning for each problem found — e.g. StatBinHex::binwidth being NaN, zero or negative. Called once per layer, before compute_group runs (which has no warnings channel of its own: the per-group call only sees &DataFrame and &ScaleSet, not the plot’s warnings sink). Default: no-op.
