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.
For convenience, we use Vector and Matrix from Russell Lab.

Install some libraries:
bash
sudo apt-get install \
liblapacke-dev \
libopenblas-dev \
python3-matplotlib
Add this to your Cargo.toml (choose the right version):
toml
[dependencies]
plotpy = "*"
```rust use plotpy::{Contour, Plot}; use russell_lab::generate3d; use std::path::Path;
fn main() -> Result<(), &'static str> { // generate (x,y,z) matrices let n = 21; let (x, y, z) = generate3d(-2.0, 2.0, -2.0, 2.0, n, n, |x, y| x * x - y * y);
// configure contour
let mut contour = Contour::new();
contour
.set_colorbar_label("temperature")
.set_colormap_name("terrain")
.set_selected_level(0.0, true);
// draw contour
contour.draw(&x, &y, &z);
// add contour to plot
let mut plot = Plot::new();
plot.add(&contour);
plot.set_labels("x", "y");
// save figure
plot.save(Path::new("/tmp/plotpy/readme_contour.svg"))?;
Ok(())
} ```
