Enum Artist 

pub enum Artist {
    Line(LineArtist),
    Scatter(ScatterArtist),
    Bar(BarArtist),
    Histogram(HistArtist),
    FillBetween(FillBetweenArtist),
}

A visual element drawn on an axes.

Artist is the primary unit of chart content. Each variant wraps a concrete artist struct that stores the data, colors, and styling needed to render one visual element. The enum provides convenience accessors (label, color, data_bounds) that dispatch to the inner type.

Variants

Line(LineArtist)

A line chart connecting (x, y) points.

Scatter(ScatterArtist)

A scatter plot of individual points.

Bar(BarArtist)

A bar chart (vertical or horizontal).

Histogram(HistArtist)

A histogram (binned frequency distribution).

FillBetween(FillBetweenArtist)

A filled region between two y-series sharing a common x-series.

Implementations

impl Artist

pub fn label(&self) -> Option<&str>

Returns the legend label for this artist, if one has been set.

The legend renderer uses this to decide which artists appear in the legend. Artists without a label are silently skipped.

pub fn color(&self) -> Color

Returns the primary color of this artist.

Used by the legend to draw a color swatch next to the label, and by any other component that needs to identify an artist’s color (e.g. tooltip rendering).

pub fn data_bounds(&self) -> (f64, f64, f64, f64)

Returns the data-space bounding box as (xmin, xmax, ymin, ymax).

The axes autoscaling logic calls this on every artist to compute the tightest axis limits that contain all visible data. If a series is empty or contains no finite values, the corresponding min/max pair falls back to (0.0, 1.0) so that the axes always have a non-zero extent.
