Struct SecAxis 

pub struct SecAxis {
    pub transform: fn(f64) -> f64,
    pub name: String,
    pub breaks: Option<Vec<f64>>,
    pub percent_of_max: bool,
}

A secondary axis specification — defines a transformation from the primary axis domain.

Example

use ggplot_rs::prelude::*;

// Temperature in Celsius on primary, Fahrenheit on secondary
let sec = SecAxis::new(|c| c * 9.0 / 5.0 + 32.0).with_name("Fahrenheit");

Fields

transform: fn(f64) -> f64

Transformation from primary axis values to secondary axis values.

name: String

Name / title for the secondary axis.

breaks: Option<Vec<f64>>

Custom break positions in primary axis coordinates.

percent_of_max: bool

Label the axis as a percentage of the primary scale’s trained data maximum (SecAxis::percent_of_max) instead of through transform.

Implementations

impl SecAxis

pub fn new(transform: fn(f64) -> f64) -> Self

Create a secondary axis with the given transformation function.

pub fn percent_of_max() -> Self

A 0–100 % axis relative to the primary scale’s trained data maximum (the value drawn at the right axis’ 100 % tick) — e.g. a Pareto chart’s cumulative share, where the maximum is the grand total. The ticks sit at their own nice percentages (0, 25, …, 100 %) rather than at the primary breaks.

pub fn with_name(self, name: &str) -> Self

pub fn with_breaks(self, breaks: Vec<f64>) -> Self

pub fn transform_value(&self, v: f64) -> f64

Transform a primary axis value to the secondary axis value.

Trait Implementations

impl Clone for SecAxis

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SecAxis

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

Formats the value using the given formatter.
