Histograms bins

[Dajamante]

Hello everyone!
Thank you for your work on Plotters :)

I used Histogram before and it plotted in the terminal as expected. But now, with a simple array looking like that:

New stuff: [
    24.0,
    5.0,
]

I get this graph!

It looks like Histogram believes there is ONE element with label 5, and ONE element with label 24, instead of 5 elements of one kind and 24 of the other kind. Even though there are plenty of examples for SVG and file printing, I am unable to find how to print to terminal in the docs :(, sorry about that.

How can I plot this map as Histogram :

Stats error map: {
    "E0308": 5,
    "E0425": 24,
}

I saw @hh made a PR for a pie chart but it does not look ready yet :) ? https://github.com/38/plotters/pull/292/commits

pub fn graph(stats: &Stats) {
    let new_stuff: Vec<f64> = stats.error_map.iter().map(|(_, e)| *e as f64).collect();
    let bins = new_stuff.len();
    println!("New stuff: {:#?}", new_stuff);
    let h = Histogram::from_slice(&new_stuff[..], HistogramBins::Count(25));
    let v = ContinuousView::new()
        .add(h)
        .x_label("Something")
        .y_label("Other thing");

    println!("{}", Page::single(&v).dimensions(50, 15).to_text().unwrap());
}
