This package implements a plotting library, with its own functions. However, internally, this package generates a Python script with Matplotlib commands. Then, this package runs the script using process::Command.
Documentation:
bash
sudo apt-get install python3-matplotlib
Add the following lines to Cargo.toml:
toml
[dependencies]
plotpy = "*"
```rust use plotpy::*; use std::path::Path;
// directory to save figures const OUTDIR: &str = "/tmp/plotpy/doctests";
fn main() -> Result<(), &'static str> { // generate (x,y,z) matrices let n = 21; let mut x = vec![vec![0.0; n]; n]; let mut y = vec![vec![0.0; n]; n]; let mut z = vec![vec![0.0; n]; n]; let (min, max) = (-2.0, 2.0); let d = (max - min) / ((n - 1) as f64); for i in 0..n { let v = min + (i as f64) * d; for j in 0..n { let u = min + (j as f64) * d; x[i][j] = u; y[i][j] = v; z[i][j] = u * u - v * v; } }
// configure and draw contour
let mut contour = Contour::new();
contour.colorbar_label = "temperature".to_string();
contour.colormap_name = "terrain".to_string();
contour.with_selected = true;
contour.selected_level = 0.0;
contour.draw(&x, &y, &z);
// add contour to plot
let mut plot = Plot::new();
plot.add(&contour);
plot.labels("x", "y");
// save figure
let path = Path::new(OUT_DIR).join("doc_contour.svg");
plot.save(&path)?;
Ok(())
} ```
