Struct GainChart 

pub struct GainChart { /* private fields */ }

A cumulative gain or lift chart as a drawable series (coordinate space (f64, f64)).

Implementations

impl GainChart

pub fn from_scores(scores: &[f64], labels: &[bool]) -> Result<Self, StatsError>

Build from predicted scores and true binary labels, defaulting to the cumulative-gain view.

pub fn mode(self, mode: GainMode) -> Self

Switch between the gain and lift views.

pub fn baseline(self, show: bool) -> Self

Show/hide the chance baseline.

pub fn color(self, color: RGBColor) -> Self

Set the line color.

pub fn stroke_width(self, width: u32) -> Self

Set the line stroke width in pixels.

Trait Implementations

impl Clone for GainChart

fn clone(&self) -> GainChart

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GainChart

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

Formats the value using the given formatter.

impl<DB: DrawingBackend> Drawable<DB> for GainChart

fn draw<I: Iterator<Item = BackendCoord>>( &self, points: I, backend: &mut DB, _parent_dim: (u32, u32), ) -> Result<(), DrawingErrorKind<DB::ErrorType>>

Actually draws the element. The key points is already translated into the image coordinate and can be used by DC directly

impl<'a> PointCollection<'a, (f64, f64)> for &'a GainChart

type Point = &'a (f64, f64)

The item in point iterator

type IntoIter = &'a [(f64, f64)]

The point iterator

fn point_iter(self) -> &'a [(f64, f64)]

framework to do the coordinate mapping
