Struct termplot::plot::Histogram

pub struct Histogram { /* private fields */ }

An histogram graph. An approximation of the distribution of data.

Examples

use termplot::*;
use rand::Rng;

let mut rng = rand::thread_rng();
let values: Vec<f64> = (0..100).map(|_| rng.gen_range(0.0f64..10.0f64)).collect();

let mut plot = Plot::default();

plot.set_domain(Domain(0.0..11.0))
    .set_codomain(Domain(0.0..45.0))
    .set_title("Graph title")
    .set_x_label("X axis")
    .set_y_label("Y axis")
    .set_size(Size::new(50, 25))
    .add_plot(Box::new(plot::Histogram::new(
        values,
        vec![0.0..2.0, 2.0..4.0, 4.0..6.0, 6.0..8.0, 8.0..10.0],
    )));

println!("{plot}");

Implementations

impl Histogram

pub fn new(values: Vec<f64>, buckets_range: Vec<Range<f64>>) -> Self

Create an histogram from data and buckets in which the data will be sorted.

For each given value, the value will increment the count of the bucket in which it resides inside.

pub fn new_with_buckets_count(values: Vec<f64>, count: u32) -> Self

Create an histogram from data and a number of buckets.

All buckets will have the same width, depending on the range of the min and max value and the number of buckets.

For each given value, the value will increment the count of the bucket in which it resides inside.

Trait Implementations

impl DrawView for Histogram

fn draw(&self, view: &View, canvas: &mut ViewCanvas<'_>)

Draw the component on the given canvas.
