graplot

'graplot' is an experimental plotting library written in Rust that is based on macroquad (internally litequad). It creates a window displaying the graphs.

Installation

Add 'graplot' as a dependency:

[dependencies]
graplot = "0.1.9"

Examples

use graplot::Plot;

let plot = Plot::new([-4., -2., 1., 4.]);
plot.show();

Multiple graphs:

use graplot::Plot;

let xs = [1., 2., 3.,];
let ys = [1.7, 3., 1.9];

let ys1 = [1.4, 1.6, 1.5];    

let ys2 = [0.9, 1.2, 1.7, 1.9, 2.];    

let mut plot = Plot::new((xs, ys));
plot.add((xs, ys1, "c-o"));
plot.add((ys2, "r-"));
plot.show();

Label the x and y axis and set a title:

use graplot::{x, Plot};

let mut plot = Plot::new((|x: f64| x.cos(), x(6.)));

plot.set_title("cosine wave");

plot.set_xlabel("x axis");
plot.set_ylabel("y axis");
plot.show();

Sine wave:

use graplot::Plot;

let mut xs = [0.; 1000]; 

let mut add = 0f64;
for idx in 0..1000 {
    xs[idx] = add/1000.;
    add += 1.;
}
    
let mut ys = [0.; 1000];
for (i, y) in ys.iter_mut().enumerate() {
    *y = (2. * std::f64::consts::PI * xs[i]).sin();
}
// or alternatively: let plot = Plot::new((|x: f64| x.sin(), x(4.)));
let plot = Plot::new((xs, ys));
plot.show();

x³ + x² - 0.08:

use graplot::{Plot, x};

// x(...) ... sets the absolute max value for x 
let plot = Plot::new((|x: f64| x.powf(3.) + x.powf(2.) - 0.08, x(1.)) );
plot.show();

x² - 0.5:

use graplot::Plot;

let plot = Plot::new(|x: f64| x.powf(2.) - 0.5);
plot.show();

Using a line description: (matplotlib)

use graplot::Plot;

// c ... cyan color, - ... solid line, o ... ring marker
let plot = Plot::new(([-4., -3., -3.4, -3.75, -4.1], "c-o"));
plot.show();

Custom scaling:

use graplot::{Desc, Plot, x};

let mut plot = Plot::new((|x: f64| x.cos(), x(2.)));
plot.set_desc(Desc {
    min_steps_x: 6.,
    spacing_x: 47.,
    ..Default::default()
});
plot.show();

Another version for miniquad is needed for this feature. Therefore is it broken. Spawning multiple windows on linux:

let mut plot = Plot::new(|x: f64| x.powf(3.) + x.powf(2.) - 0.08);
plot.set_title("x^3 + x^2 - 0.08");
let h = plot.show_threaded() // show_threaded() is currently linux only;

let mut plot = Plot::new(|x: f64| x.powf(2.) + 0.08);
plot.set_title("x²");
plot.show();

h.join().unwrap() // you need to close both windows

Changelog

• 0.1.9: fixed bug

• 0.1.7: Set graph color, custom x & y "line" spacing and step size | "custom scaling"
• 0.1.6: Label x axis, litequad
• 0.1.5: y axis, set title, /mutliple windows on linux/ | yanked
• 0.1.4: Multiple graphs
