Struct CharSet 

pub struct CharSet {

    pub horizontal: char,
    pub vertical_line: char,
    pub arc_down_right: char,
    pub arc_down_left: char,
    pub arc_up_right: char,
    pub arc_up_left: char,
    pub end_cap: char,
    pub start_cap: char,
    pub up_right: char,
    pub down_horizontal: char,
    pub dash_horizontal: char,
    pub double_dash_horizontal: char,
    pub heavy_dash_horizontal: char,
    pub dot_horizontal: char,
}

Defines the set of characters used to draw a data series on the graph.

Each field controls a specific part of the line rendering — horizontal runs, vertical segments, corner arcs, NaN gap caps, axis corners, and tick marks. Swap out individual characters to change the visual style of a series without affecting the rendering logic.

Use create_char_set to create a uniform set where every character is the same (e.g. * or •). Use struct update syntax (..Default::default()) to override only the fields you care about while keeping the rest as the defaults from DEFAULT_CHAR_SET.

Example

use asciigraph::options::CharSet;

// Override only the horizontal and vertical characters.
let partial = CharSet {
    horizontal: '=',
    vertical_line: '|',
    ..Default::default()
};

Fields

horizontal: char

Horizontal line character used for flat segments. Default: ─

vertical_line: char

Vertical line character used for steep segments. Default: │

arc_down_right: char

Corner arc going down and to the right (rising series). Default: ╭

arc_down_left: char

Corner arc going down and to the left (falling series). Default: ╮

arc_up_right: char

Corner arc going up and to the right (falling series). Default: ╰

arc_up_left: char

Corner arc going up and to the left (rising series). Default: ╯

end_cap: char

End cap drawn at the last finite point before a NaN gap. Default: ╴

start_cap: char

Start cap drawn at the first finite point after a NaN gap. Default: ╶

up_right: char

Bottom-left corner character for the X-axis. Default: └

down_horizontal: char

Tick mark character used on the X-axis. Default: ┬

dash_horizontal: char

Dashed horizontal character used for threshold lines. Default: ╌

double_dash_horizontal: char

Dashed horizontal character used for mean annotation. Default: ┄

heavy_dash_horizontal: char

Heavy dashed horizontal character used for median annotation. Default: ╍

dot_horizontal: char

Dotted horizontal character used for standard deviation annotation. Default: ·

impl Default for CharSet

fn default() -> Self

Returns the “default value” for a type.
