Struct GeomHistogram 

pub struct GeomHistogram {
    pub bins: usize,
    pub binwidth: Option<f64>,
    pub fill: (u8, u8, u8),
    pub color: (u8, u8, u8),
    pub alpha: f64,
}

Histogram geometry (bar chart with StatBin).

Fields

bins: usize

binwidth: Option<f64>

fill: (u8, u8, u8)

color: (u8, u8, u8)

alpha: f64

Implementations

impl GeomHistogram

pub fn with_binwidth(self, width: f64) -> Self

Set bin width (overrides bins count).

pub fn with_bins(self, bins: usize) -> Self

Set number of bins.

Trait Implementations

impl Default for GeomHistogram

fn default() -> Self

Returns the “default value” for a type.

impl Geom for GeomHistogram

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.
