Simple Chart

This repository contains stuff to represent iterator of (T, T), that is convertable to (f64,f64), as line chart in bmp format.

Example 1. One serie and auto calculated axis returned as Vec<u8>:

    let mut chart = Chart::new(200, 100, "#ffffff", "#000000")
        .unwrap();

    let v: Vec<_> = vec![(1.2,2.3), (3.4, 4.5), (5.6, 6.7)];
    let serie = Serie::new(v.into_iter(), "#ff0000").unwrap();
    let series = vec![serie];
    
    let bmp = chart.draw(series.into_iter());

Example 2. One serie, calculated from included macros formula!,

and manual setted axis x:

    let mut chart = Chart::new(400, 500, "#f14500", "#0027ff")
        .unwrap()
        .add_axis_x(Axis::new(-2.0, 2.0, 7, 2));

    let v = formula!(y(x) = x.sin(), x = [-3.14, 3.14; 0.1]);
    let serie = Serie::new(v.into_iter(), "#ffff00").unwrap();
    let series = vec![serie];

    let bmp = chart.draw(series.into_iter());

Example 3. Two series and manual setted axis x and y:

    let mut chart = Chart::new(740, 480, "#000000", "#ffffff")
        .unwrap()
        .add_axis_x(Axis::new(-2.0, 2.0, 7, 2))
        .add_axis_y(Axis::new(-2.0, 2.0, 7, 2));

    let v1 = formula!(y(x) = x.sin(), x = [-3.14, 3.14; 0.1]);
    let v2 = formula!(y(x) = x.cos(), x = [-3.14, 3.14; 0.1]);
    let serie1 = Serie::new(v1.into_iter(), "#ff0000").unwrap();
    let serie2 = Serie::new(v2.into_iter(), "#00ff00").unwrap();
    let series = vec![serie1, serie2];

    let bmp = chart.draw(series.into_iter());

Usage

Put this in your Cargo.toml:

[dependencies]
simple-chart = "*"

And this in your crate root:

extern crate simple_chart;
use simple_chart::{Chart, Serie, Axis, Point};
