Provided Methods§

Source

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

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();

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
