}

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.

Step(StepArtist)

A step (staircase) chart connecting data points.

Stem(StemArtist)

A stem (lollipop) chart from data points.

BoxPlot(BoxPlotArtist)

A box-and-whisker plot showing distribution summaries.

ErrorBar(ErrorBarArtist)

An error bar plot showing data points with uncertainty bars.

Heatmap(HeatmapArtist)

A heatmap showing a 2D grid of values mapped to colors.

Pie(PieArtist)

A pie chart showing proportional wedge slices.

Violin(ViolinArtist)

A violin plot showing kernel density estimates of distributions.

Contour(ContourArtist)

A contour or filled contour plot over a 2D grid.

Polar(PolarArtist)

A polar line or filled radar chart in polar coordinates.

Hexbin(HexbinArtist)

A hexagonal binning plot showing point density as colored hexagons.

Waterfall(WaterfallArtist)

A waterfall chart showing cumulative positive and negative changes.

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.

Trait Implementations

impl Clone for Artist

fn clone(&self) -> Artist

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Artist

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

Formats the value using the given formatter.
