Examples

This code

extern crate rasciigraph;

use rasciigraph::{plot, Config};

fn main() {
    println!(
        "{}",
        plot(
            vec![
                0.0, 0.0, 0.0, 0.0, 1.5, 0.0, 0.0, -0.5, 9.0, -3.0, 0.0, 0.0, 1.0, 2.0, 1.0, 0.0,
                0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 1.5, 0.0, 0.0, -0.5, 8.0, -3.0, 0.0, 0.0, 1.0,
                2.0, 1.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 1.5, 0.0, 0.0, -0.5, 10.0, -3.0,
                0.0, 0.0, 1.0, 2.0, 1.0, 0.0, 0.0, 0.0, 0.0
            ],
            Config::default()
                .with_offset(10)
                .with_height(10)
                .with_caption("I'm a doctor, not an engineer.".to_string())
        )
    );
}

Produces an output like this

With 0.2.0 version you can also plot multi series

fn main() {
    let res = rasciigraph::plot_many(
        vec![
            vec![0.0f64, 1.0, 0.0],
            vec![2.0, 3.0, 4.0, 3.0, 2.0],
            vec![4.0, 5.0, 6.0, 7.0, 6.0, 5.0, 4.0],
        ],
        rasciigraph::Config::default().with_width(21),
    );
    print!("{}", res);
}

This is the output

 7.00 ┤        ╭──╮
