Struct astrup::chart::line::Line

pub struct Line { /* fields omitted */ }

Line struct

With this chart, one is able to display data using lines. Straight lines are drawn between coordinates, determined by the input data points. You can e.g. alter the line color, the dash pattern, and the stroke style.

Note The input can be any data container that implements the AsArray trait (e.g. a Vec, or ndarray Array), but the contained data must be f64. Ideally, this should be any integer or float, but I have not been able to implement a generic over them also. This is perhaps connected to things like higher kinded types and the like, which I think will come soon.

Methods

impl Line

fn new<'a, I: AsArray<'a, f64>>(x_data_coords: I, y_data_coords: I) -> Line
