sin & cosin

use plotters::prelude::*;

fn main() {
    let root_area = BitMapBackend::new("images/2.12.png", (600, 400))
    .into_drawing_area();
    root_area.fill(&WHITE).unwrap();

    let mut ctx = ChartBuilder::on(&root_area)
        .set_label_area_size(LabelAreaPosition::Left, 40)
        .set_label_area_size(LabelAreaPosition::Bottom, 40)
        .caption("Legend", ("sans-serif", 40))
        .build_cartesian_2d(-4.0..4.0, -1.2..1.2)
        .unwrap();

    ctx.configure_mesh().draw().unwrap();

    let x_kps: Vec<_> = (-80..80).map(|x| x as f64 / 20.0).collect();
    ctx.draw_series(LineSeries::new(x_kps.iter().map(|x| (*x, x.sin())), &RED))
        .unwrap()
        .label("Sine")
        .legend(|(x, y)| PathElement::new(vec![(x, y), (x + 20, y)], &RED));

    ctx.draw_series(LineSeries::new(x_kps.iter().map(|x| (*x, x.cos())), &BLUE))
        .unwrap()
        .label("Cosine")
        .legend(|(x, y)| PathElement::new(vec![(x, y), (x + 20, y)], &BLUE));

    ctx.configure_series_labels()
        .border_style(&BLACK)
        .background_style(&WHITE.mix(0.8))
        .draw()
        .unwrap();
}

legend 보면 됨
