Struct AxisSpec 

pub struct AxisSpec<'a> {
    pub bounds: [f64; 2],
    pub title: &'a str,
    /* private fields */
}

One axis: its range, how its ticks are chosen and written, and its title.

Fields

bounds: [f64; 2]

title: &'a str

Implementations

impl<'a> AxisSpec<'a>

pub fn fixed( bounds: [f64; 2], ticks: Vec<f64>, label: TickLabel<'a>, title: &'a str, ) -> Self

An axis ticked at ticks, written by label. Evenly spaced ticks thin out keeping both ends.

pub fn ends_and_middle( bounds: [f64; 2], label: TickLabel<'a>, title: &'a str, ) -> Self

Ticks at the ends of bounds and halfway between.

pub fn numbers(bounds: [f64; 2], numbers: &AxisNumbers, title: &'a str) -> Self

A numeric axis over bounds holding numbers, ticked at nice values (whole ones when the numbers are whole), every tick in one format.

pub fn y_numbers( bounds: [f64; 2], numbers: &AxisNumbers, title: &'a str, ) -> Self

A numeric y axis: widened out to the nice ticks either side of its range, so it starts and ends on a label, short of a tick that would leave most of a step empty (ticks::widen_snug).

pub fn calendar( bounds: [f64; 2], kind: XAxisTemporalKind, numbers: &AxisNumbers, title: &'a str, ) -> Self

A time axis of kind over bounds, ticked on calendar boundaries; numbers writes a value past what a date can stand for.

pub fn numbers_as( bounds: [f64; 2], numbers: &AxisNumbers, title: &'a str, shown: impl Fn(f64) -> f64 + 'a, ) -> Self

A numeric axis whose position v stands for the number shown(v), as on a log scale: ticked at its ends and middle, its format chosen from the numbers they stand for.

pub fn y_log(bounds: [f64; 2], numbers: &AxisNumbers, title: &'a str) -> Self

A log-scale y axis (position v is exp_m1(v)): ticks at nice values (1, 10, 100, with 2 and 5 between when there is room), widened to the ticks around its range, one format throughout.

pub fn padded(self, width: usize) -> Self

The same axis, its labels right-aligned in at least width cells.

pub fn tick_sets( &self, length: f64, spacing: f64, least: f64, minor_gap: f64, ) -> Vec<Vec<TickSet>>

The ways to tick this axis of length, preferred first: about one label per spacing, then coarser, none closer than least, minor ticks at least minor_gap apart (cells on screen, points in a file). A second group follows when the first may be empty: a time axis’s ends and middle.
