Function histogram 

pub fn histogram<V: ToString>(
    data: &[V],
    options: HistogramOptions,
) -> Result<Plot<BarplotGraphics>, HistogramError>

Constructs a histogram by binning data and delegating rendering to barplot.

Examples

use unicode_plot::{HistogramOptions, histogram};

let mut options = HistogramOptions::default();
options.title = Some("Example Histogram".to_owned());

let data = vec![1.0, 1.5, 1.7, 2.0, 2.1, 2.9, 3.2, 3.8, 4.0, 4.1];
let plot = histogram(&data, options).unwrap();

let mut buf = Vec::new();
plot.render(&mut buf, false).unwrap();
let rendered = String::from_utf8(buf).unwrap();
assert!(rendered.contains("Example Histogram"));

Errors

Returns HistogramError::EmptyData for empty input, HistogramError::InvalidBinCount when nbins is Some(0), HistogramError::InvalidNumericValue if any value is non-finite, and HistogramError::Barplot if barplot construction fails.
