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() -> RadialLine<T>

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

where I: IntoIterator<Item = T>,

Set the data of the RadialLine.

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

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) -> RadialLine<T>

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) -> RadialLine<T>

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

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

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>) -> RadialLine<T>

Set the stroke color of the RadialLine.

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

Set the stroke width of the RadialLine.

pub fn dot(self) -> RadialLine<T>

Draw a dot on every point.

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

Set the size of the dots on the RadialLine.

pub fn dot_fill(self, fill: impl Into<Background>) -> RadialLine<T>

Set the fill of the dots on the RadialLine.

pub fn dot_stroke(self, stroke: impl Into<Hsla>) -> RadialLine<T>

Set the 1px border color of the dots on the RadialLine. Defaults to the dot fill when it is a solid color.

pub fn dot_fill_color(self, color: impl Into<Hsla>) -> RadialLine<T>

👎Deprecated since 0.7.0:

use dot_fill

pub fn dot_stroke_color(self, color: impl Into<Hsla>) -> RadialLine<T>

👎Deprecated since 0.7.0:

use dot_stroke

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

Paint the RadialLine.

Trait Implementations

impl<T> Default for RadialLine<T>

fn default() -> RadialLine<T>

Returns the “default value” for a type.
