Struct GeomLabel 

pub struct GeomLabel {
    pub size: f64,
    pub color: (u8, u8, u8),
    pub fill: (u8, u8, u8),
    pub alpha: f64,
    pub padding: f64,
    pub hjust: f64,
    pub vjust: f64,
    pub fontfamily: String,
    pub check_overlap: bool,
}

Label geometry — like text but with a background rectangle.

Fields

size: f64

color: (u8, u8, u8)

fill: (u8, u8, u8)

alpha: f64

padding: f64

hjust: f64

Horizontal justification: 0.0 = left, 0.5 = center (default), 1.0 = right.

vjust: f64

Vertical justification: 0.0 = bottom, 0.5 = middle (default), 1.0 = top.

fontfamily: String

Font family name (informational; actual rendering depends on backend).

check_overlap: bool

When true, skip drawing labels that overlap previously drawn labels.

Implementations

impl GeomLabel

pub fn with_hjust(self, hjust: f64) -> Self

pub fn with_vjust(self, vjust: f64) -> Self

pub fn with_fontfamily(self, family: &str) -> Self

pub fn with_check_overlap(self, check: bool) -> Self

Trait Implementations

impl Default for GeomLabel

fn default() -> Self

Returns the “default value” for a type.

impl Geom for GeomLabel

fn draw( &self, data: &DataFrame, coord: &dyn Coord, scales: &ScaleSet, _theme: &Theme, backend: &mut dyn DrawBackend, ) -> Result<(), RenderError>

Draw this geometry.

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

Required aesthetics.

fn default_stat(&self) -> Box<dyn Stat>

Default stat for this geom.

fn default_position(&self) -> Box<dyn Position>

Default position adjustment.

fn default_params(&self) -> GeomParams

Non-mapped visual defaults.

fn name(&self) -> &str

Name for debug/display.

fn set_series_color(&mut self, _color: (u8, u8, u8))

Apply a brand/primary color to this geom’s single-series default (its color or fill). The build pipeline calls this only when the layer has no color/fill aesthetic mapped, so an explicit mapping always wins. The default is a no-op; series geoms override it.
