fraction

lq.tick-format.fraction(ticks, simplify: true, simplify-integers: true, suffix: none, suffix-position: "outside", omit-unity: true, tick-info: (:), ..args)(source)

Formats linear ticks (see tick-locate.linear) with automatic fractions when the tick distance is a fraction of 1.

#lq.diagram(
  xlim: (-0.5, 1),
  xaxis: (
    tick-distance: 1 / 4,
    format-ticks: lq.tick-format.fraction
  )
)

A suffix like $\pi$ can be inserted for $\pi$-based scales, see also tick-locate.linear.

#lq.diagram(
  xlim: (-calc.pi / 2, calc.pi),
  xaxis: (
    tick-distance: 1 / 4,
    locate-ticks: lq.tick-locate.linear.with(unit: calc.pi),
    format-ticks: lq.tick-format.fraction.with(suffix: $pi$)
  )
)

Parameters

ticks : array

The ticks to format.

simplify : bool    default: true

Whether to simplify fractions, like $2/4$ to $1/2$.

simplify-integers : bool    default: true

Whether to simplify integers − like $4/2$ to $2$ − and show no fraction.

suffix : content    default: none

A suffix to display with each tick label, except with 0.

suffix-position : "outside" | "numerator"    default: "outside"

Whether to place the suffix in the numerator or outside the fraction.

omit-unity : bool    default: true

Whether to omit $1$ and $-1$ in combination with a suffix, e.g., $-\pi$ instead of $-1\pi$.

tick-info : dictionary    default: (:)

Additional information from the tick locator.

..args : any

Arguments that are ignored by this formatter.
