String labels for xtic

[bonorumetmalorum]

I was creating a bar chart using this library but found that it would not allow for strings to be attached to xtics. If this could be added it would be immensely useful for creating bar charts.

You can do this:

let mut fg = Figure::new();
c.set_term(&mut fg);

fg.axes2d()
    .boxes(&[1., 2., 3.], &[1., 2., 3.], &[Color("gray"), BorderColor("black")])
    .set_x_ticks_custom(
        vec![
            Major(1. as f32, Fix("A".into())),
            Major(2. as f32, Fix("B".into())),
            Major(3. as f32, Fix("C".into()))
        ],
        &[],
        &[],
    )
    .set_y_range(Fix(0.0), Auto);
fg.show();

to get:

Or, if your have an array of labels:

let mut fg = Figure::new();
c.set_term(&mut fg);

let x = [1., 2., 3.];
let y = [1., 2., 3.];
let l = ["A", "B", "C"];

fg.axes2d()
    .boxes(&x, &y, &[Color("gray"), BorderColor("black")])
    .set_x_ticks_custom(
        x.iter().zip(&l).map(|(&x, &l)| Major(x as f32, Fix(l.into()))),
        &[],
        &[],
    )
    .set_y_range(Fix(0.0), Auto);
fg.show();
