    fn with_key_point_func<F: Fn(usize) -> Vec<Self::Value> + 'static>(

Provided methods

fn with_key_point_func<F: Fn(usize) -> Vec<Self::Value> + 'static>(
    self,
    func: F
) -> WithKeyPointMethod<Self::CoordDescType>[src]

Bind a existing coordinate spec with a given key points algorithm. See WithKeyPointMethod for more details. Example:

use plotters::prelude::*;
use plotters_bitmap::BitMapBackend;
let mut buffer = vec![0;1024*768*3];
let root = BitMapBackend::with_buffer(&mut buffer, (1024, 768)).into_drawing_area();
let mut chart = ChartBuilder::on(&root)
   .build_cartesian_2d(
       (0..100).with_key_point_func(|n| (0..100 / n as i32).map(|x| x * 100 / n as i32).collect()),
       0..10
).unwrap();
chart.configure_mesh().draw().unwrap();
