Struct PieLayout 

pub struct PieLayout { /* private fields */ }

Computes pie layout angles from data values.

Implementations

impl PieLayout

pub fn new() -> Self

Create a new PieLayout with default settings (full circle, unsorted).

pub fn start_angle(self, angle: f64) -> Self

Set the start angle in radians.

pub fn end_angle(self, angle: f64) -> Self

Set the end angle in radians.

pub fn sort(self, sort: bool) -> Self

Set whether to sort slices by value (descending).

pub fn layout(&self, values: &[f64]) -> Vec<PieSlice>

Compute pie slices from data values. Each value gets a proportional angle within [start_angle, end_angle].

Trait Implementations

impl Default for PieLayout

fn default() -> Self

Returns the “default value” for a type.
