Struct AxisBounds 

pub struct AxisBounds { /* private fields */ }

The [min, max] range of one axis, in the plot’s f64 coordinate space.

The units are those of the source GraphData, which the adapter is generic over: for a payoff (#27) the x range is the underlying price and the y range is P&L; for a vol smile (#47) x is the strike and y is implied volatility; for a Greek curve x is the strike and y is the selected Greek. The adapter carries the numeric range only — the semantic axis title is supplied by the screen.

Invariant

Both endpoints are finite and ordered (min <= max) by construction: the fields are private and new is the only constructor, rejecting any NaN/Inf or inverted range before it can reach a ratatui axis. Read them through min / max / to_array.

Degenerate intervals are padded at the seam

A single-point or flat series would otherwise yield min == max — a zero-width range ratatui’s chart rejects entirely, painting a BLANK chart. The projection pads such an interval (the internal padded step), so the axis always has real width and a flat line stays visible; the pad size is documented on that step.

Implementations

impl AxisBounds

pub fn new(min: f64, max: f64) -> Option<Self>

Construct validated bounds, or None when the “finite, ordered” invariant fails: both min and max must be finite (no NaN/Inf) and ordered (min <= max). This is the ONLY way to build an AxisBounds, so a downstream caller can never hand a non-finite or inverted range to a ratatui axis. A degenerate min == max is accepted here (it is finite and ordered); the projection expands it via the internal padded step.

pub fn min(self) -> f64

The axis minimum — finite and <= max by construction.

pub fn max(self) -> f64

The axis maximum — finite and >= min by construction.

pub fn to_array(self) -> [f64; 2]

The bounds as the [f64; 2] array Axis::bounds consumes.
