CategoryAxis

pub struct CategoryAxis {
  labels : Array[String]
}

An ordered converter from string categories to numeric axis positions.

Categories are assigned positions in first-seen order. Repeated labels reuse the position that was assigned to their first occurrence.

CategoryAxis::encode

source

fn CategoryAxis::encode(self : CategoryAxis, values : Array[String]) -> (Array[Double], CategoryAxis)

Convert string values to stable numeric positions. Empty strings are valid categories; the String element type rejects non-string values before this function is called.

CategoryAxis::labels

source

fn CategoryAxis::labels(self : CategoryAxis) -> Array[String]

Return all known labels in their stable first-seen order.

CategoryAxis::length

source

fn CategoryAxis::length(self : CategoryAxis) -> Int

Return the number of known categories.

CategoryAxis::tick_labels

source

fn CategoryAxis::tick_labels(self : CategoryAxis) -> Array[String]

Return category labels in their stable first-seen order.

CategoryAxis::tick_positions

source

fn CategoryAxis::tick_positions(self : CategoryAxis) -> Array[Double]

Return the numeric position for each known category.

CategoryAxis::with_labels

source

fn CategoryAxis::with_labels(self : CategoryAxis, labels : Array[String]) -> CategoryAxis

Add labels to this converter and return the extended converter.
