Struct RadialLine 

pub struct RadialLine<T> { /* private fields */ }

A radial line generator, like d3.lineRadial.

Points are placed around the center of the plot bounds. The angle accessor returns the angle in radians, with 0 at 12 o’clock and positive angles proceeding clockwise. The radius accessor returns the distance (in pixels) from the center.

Call RadialLine::closed to connect the last point back to the first (like d3.curveLinearClosed), and RadialLine::fill to fill the enclosed polygon, e.g. for radar charts.

Unlike Line, the accessors also receive the datum index, matching d3’s (d, i) accessor form, since radial charts typically derive the angle from the index (e.g. i * TAU / n).

Implementations

impl<T> RadialLine<T>

pub fn new() -> Self

pub fn data<I>(self, data: I) -> Self

where I: IntoIterator<Item = T>,

Set the data of the RadialLine.

pub fn angle<F>(self, angle: F) -> Self

where F: Fn(&T, usize) -> Option<f32> + 'static,

Set the angle accessor of the RadialLine.

The accessor is called with the datum and its index, and returns the angle in radians, with 0 at 12 o’clock and positive angles proceeding clockwise.

pub fn radius<F>(self, radius: F) -> Self

where F: Fn(&T, usize) -> Option<f32> + 'static,

Set the radius accessor of the RadialLine.

The accessor is called with the datum and its index, and returns the distance (in pixels) from the center.

pub fn closed(self) -> Self

Connect the last point back to the first, like d3.curveLinearClosed.

pub fn fill(self, fill: impl Into<Background>) -> Self

Set the fill color of the polygon enclosed by the RadialLine.

The fill path is always closed, regardless of RadialLine::closed.

pub fn stroke(self, stroke: impl Into<Background>) -> Self

Set the stroke color of the RadialLine.

pub fn stroke_width(self, stroke_width: impl Into<Pixels>) -> Self

Set the stroke width of the RadialLine.

pub fn dot(self) -> Self

Show dots on the RadialLine.

pub fn dot_size(self, dot_size: impl Into<Pixels>) -> Self

Set the size of the dots on the RadialLine.

pub fn dot_fill_color(self, dot_fill_color: impl Into<Hsla>) -> Self

Set the fill color of the dots on the RadialLine.

pub fn dot_stroke_color(self, dot_stroke_color: impl Into<Hsla>) -> Self

Set the stroke color of the dots on the RadialLine.

pub fn paint(&self, bounds: &Bounds<Pixels>, window: &mut Window)

Paint the RadialLine.

Trait Implementations

impl<T> Default for RadialLine<T>

fn default() -> Self

Returns the “default value” for a type.
