Struct AxisTransform 

pub struct AxisTransform { /* private fields */ }

Maps data-space coordinates along one axis to pixel positions.

An axis transform stores origin, span, pixel count, optional log scale, and optional flip (used for the y-axis so that higher values appear at the top of the terminal).

Implementations

impl AxisTransform

pub fn new( origin: f64, span: f64, pixels: usize, scale: Scale, flip: bool, ) -> Option<Self>

Creates a new axis transform. Returns None when origin or span is non-finite, span is zero, or pixels is zero.

pub const fn origin(self) -> f64

The origin of the data range on this axis.

pub const fn span(self) -> f64

The data-space span along this axis.

pub const fn pixels(self) -> usize

The number of pixels along this axis.

pub const fn scale(self) -> Scale

The scale applied before coordinate mapping.

pub const fn flip(self) -> bool

Whether this axis is flipped (y-axis: higher values at top).

pub fn data_to_pixel(self, value: f64) -> Option<i32>

Converts a data-space value to a pixel coordinate.

Returns None for non-finite values, values outside the log domain (zero or negative with a log scale), or results that overflow i32.

Trait Implementations

impl Clone for AxisTransform

fn clone(&self) -> AxisTransform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AxisTransform

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

Formats the value using the given formatter.

impl PartialEq for AxisTransform

fn eq(&self, other: &AxisTransform) -> 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.
