Struct TrendRange 

pub struct TrendRange {
    pub lo: f64,
    pub hi: f64,
}

The value interval a trend maps onto its plot’s height: lo lands on the baseline, hi on the top edge, and values outside clamp to the plot.

Fields

lo: f64

hi: f64

Implementations

impl TrendRange

pub fn up_to(max: f64) -> TrendRange

0..=max, with max floored away from zero so the projection never divides by ~0.

pub fn fit<T>(data: &[T]) -> TrendRange

where T: Copy + Into<f64>,

The data’s own min..=max. A series flatter than half a unit widens by one either way, so a constant series sits mid-band instead of pinned to an edge. Empty or non-finite data falls back to 0..=1.

pub fn fraction(self, value: f64) -> f64

Where value sits in the range, clamped to 0..=1.

Trait Implementations

impl Clone for TrendRange

fn clone(&self) -> TrendRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TrendRange

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

Formats the value using the given formatter.

impl PartialEq for TrendRange

fn eq(&self, other: &TrendRange) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
