Struct AreaGenerator 

pub struct AreaGenerator { /* private fields */ }

Generates SVG path d strings for area charts.

Implementations

impl AreaGenerator

pub fn new() -> Self

Create a new AreaGenerator with Linear curve type.

pub fn curve(self, curve: CurveType) -> Self

Set the curve interpolation type.

pub fn generate_line(&self, points: &[(f64, f64, f64)]) -> String

Generate an SVG path for just the top edge of the area (the stroke line).

This traces only the (x, y1) points — no baseline return, no close. Used to render a visible stroke line on top of the filled area.

pub fn generate(&self, points: &[(f64, f64, f64)]) -> String

Generate an SVG path from a series of (x, y0, y1) points.

The area is formed by:

1. Forward path along (x, y1) – the top line
2. Reverse path along (x, y0) – the bottom line (reversed)
3. Close with “Z”

For non-stacked areas, y0 is typically the baseline (e.g., the bottom of the chart).

Trait Implementations

impl Default for AreaGenerator

fn default() -> Self

Returns the “default value” for a type.
