Struct SecAxis 

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

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.

linear: Option<(f64, f64)>

secondary = primary * scale + offset (SecAxis::linear): the axis gets its own nice ticks in the secondary range.

labeller: Option<SecLabeller>

Formats the secondary axis’ tick values (SecAxis::with_labeller); None uses the plot’s number format.

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 linear(scale: f64, offset: f64) -> Self

A linear secondary axis: secondary = primary * scale + offset, e.g. a second measure drawn rescaled into the primary range (a combo chart’s right axis). Its ticks sit at nice values of the secondary range, not at the primary breaks. A zero or non-finite scale falls back to the identity.

pub fn with_labeller( self, f: impl Fn(f64) -> String + Send + Sync + 'static, ) -> Self

Format the secondary axis’ tick labels with f (e.g. a currency or percent format of the second measure).

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

Performs copy-assignment from source.

impl Debug for SecAxis

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