Struct ratatui::widgets::Sparkline

source · 
pub struct Sparkline<'a> { /* private fields */ }
Expand description

Widget to render a sparkline over one or more lines.

You can create a Sparkline using Sparkline::default.

Sparkline can be styled either using Sparkline::style or preferably using the methods provided by the Stylize trait.

§Setter methods

§Examples

use ratatui::{prelude::*, widgets::*};

Sparkline::default()
    .block(Block::default().title("Sparkline").borders(Borders::ALL))
    .data(&[0, 2, 3, 4, 1, 4, 10])
    .max(5)
    .direction(RenderDirection::RightToLeft)
    .style(Style::default().red().on_white());

Implementations§

pub fn style<S: Into<Style>>(self, style: S) -> Self

Sets the style of the entire widget.

style accepts any type that is convertible to Style (e.g. Style, Color, or your own type that implements Into<Style>).

The foreground corresponds to the bars while the background is everything else.

pub const fn max(self, max: u64) -> Self

Sets the maximum value of bars.

Every bar will be scaled accordingly. If no max is given, this will be the max in the dataset.

source

pub const fn bar_set(self, bar_set: Set) -> Self

Sets the characters used to display the bars.

Can be symbols::bar::THREE_LEVELS, symbols::bar::NINE_LEVELS (default) or a custom Set.
