Struct Histogram 

pub struct Histogram<'a, S, V>
where
    S: Schema,
    V: View<S>,
{ /* private fields */ }

The histogram widget.

A histogram represents the sole display dimension as a Binnable type. The dataset’s values are collected based off how they bin across the range defined by 1st dimension. The number of bins is configured at initialization.

use flat::*;

let schema = Schemas::one("Things");
let dataset = DatasetBuilder::new(schema)
    .add((0,))
    .add((0,))
    .add((1,))
    .build();
let view = dataset.count();
let flat = Histogram::new(&view, 2)
    .render(Render::default());
assert_eq!(
    format!("\n{}", flat.to_string()),
    r#"
Things  |Sum(Count)
[0, 1)  |**
[1, 2]  |*"#);

pub fn new(view: &'a V, bins: usize) -> Self

Construct a histogram widget from the provided view and number of bins.

pub fn render(self, config: Render<HistogramConfig>) -> Flat
