Grid example

[krestomantsi]

Please do make a simple example on how to use set_x_grid/set_y_grid cause either the doc is misleading or this is a bug. thank you.

  let mut fg = Figure::new();
  let x02 = Array::linspace(-1.0, 1.0, 100)
      .insert_axis(Axis(1))
      .mapv(|xi| xi as f32);
  let y02 = mlp.forward(&x02);
  fg.axes2d()
      .points(&x0, &y0, &[Caption("data"), Color("blue")]);
  //grid??
  fg.axes2d().set_x_grid(true).set_y_grid(true);

  fg.save_to_png("plot.png", 800, 600)
      .expect("Unable to save plot");
  println!("Plot saved");

You want to do:

let ax = fg.axes2d();
ax.points(&x0, &y0, &[Caption("data"), Color("blue")]);
ax.set_x_grid(true).set_y_grid(true);

Your snippet is creating a second axis, which I guess gets overlapped by the first axis? That could be a bug in principle.
