Struct ZeroLine 

pub struct ZeroLine {
    pub color: AnsiColor,
    pub character: char,
}

A horizontal reference line drawn at Y = 0.0 across the data area.

The zero line is only rendered when the data range straddles zero — if all values are positive or all negative, this option has no effect. It is rendered before the data series so that series arc characters always appear on top.

Example

use asciigraph::{plot, Config, ZeroLine, AnsiColor};

let data = vec![-3.0, -1.0, 0.0, 1.0, 3.0];
let graph = plot(&data, Config::default().zero_line(ZeroLine::new()));

Fields

color: AnsiColor

The ANSI color used to render the zero line. Defaults to AnsiColor::DEFAULT (no color).

character: char

The character used to draw the zero line. Defaults to ─ (DEFAULT_CHAR_SET.horizontal).

Implementations

impl ZeroLine

pub fn new() -> Self

Creates a zero line using the default horizontal character and no color.

pub fn with_color(color: AnsiColor) -> Self

Creates a zero line rendered in a specific ANSI color. Uses the default horizontal character.

pub fn with_char_and_color(character: char, color: AnsiColor) -> Self

Creates a zero line with both a custom character and a custom ANSI color.
