Function fitting_range

pub fn fitting_range<'a, T, I>(iter: I) -> Range<T> 
where
    I: IntoIterator<Item = &'a T>,
    T: 'a + Zero + One + PartialOrd + Clone,

Build a range that fits the data

• iter: the iterator over the data
• returns The resulting range

use plotters::data::fitting_range;

let data = [4, 14, -2, 2, 5];
let range = fitting_range(&data);
assert_eq!(range, std::ops::Range { start: -2, end: 14 });
