Struct Axis

Source 
pub struct Axis<'a> { /* private fields */ }
Expand description

An X or Y axis for the Chart widget

An axis can have a title which will be displayed at the end of the axis. For an X axis this is the right, for a Y axis, this is the top.

You can also set the bounds and labels on this axis using respectively Axis::bounds and Axis::labels.

See Chart::x_axis and Chart::y_axis to set an axis on a chart.

§Example

use ratatui::style::{Style, Stylize};
use ratatui::widgets::Axis;

let axis = Axis::default()
    .title("X Axis")
    .style(Style::default().gray())
    .bounds([0.0, 50.0])
    .labels(["0".bold(), "25".into(), "50".bold()]);

Implementations§

Source§

impl<'a> Axis<'a>

Source

pub fn title<T>(self, title: T) -> Axis<'a>
where T: Into<Line<'a>>,

Sets the axis title

It will be displayed at the end of the axis. For an X axis this is the right, for a Y axis, this is the top.

This is a fluent setter method which must be chained or used as it consumes self

Source

pub const fn bounds(self, bounds: [f64; 2]) -> Axis<'a>

Sets the bounds of this axis

In other words, sets the min and max value on this axis.

This is a fluent setter method which must be chained or used as it consumes self

Source

pub fn labels<Labels>(self, labels: Labels) -> Axis<'a>
where Labels: IntoIterator, <Labels as IntoIterator>::Item: Into<Line<'a>>,

Sets the axis labels

  • For the X axis, the labels are displayed left to right.
  • For the Y axis, the labels are displayed bottom to top.

Currently, you need to give at least two labels or the render will panic. Also, giving more than 3 labels is currently broken and the middle labels won’t be in the correct position, see issue 334.

labels is a vector of any type that can be converted into a Line (e.g. &str, String, &Line, Span, …). This allows you to style the labels using the methods provided by Line. Any alignment set on the labels will be ignored as the alignment is determined by the axis.

This is a fluent setter method which must be chained or used as it consumes self

§Examples
use ratatui::style::Stylize;
use ratatui::widgets::Axis;

let axis = Axis::default()
    .bounds([0.0, 50.0])
    .labels(["0".bold(), "25".into(), "50".bold()]);
Source

pub fn style<S>(self, style: S) -> Axis<'a>
where S: Into<Style>,

Sets the axis style

This is a fluent setter method which must be chained or used as it consumes self

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

§Example

Axis also implements Stylize which mean you can style it like so

use ratatui::style::Stylize;
use ratatui::widgets::Axis;

let axis = Axis::default().red();
Source

pub const fn labels_alignment(self, alignment: HorizontalAlignment) -> Axis<'a>

Sets the labels alignment of the axis

The alignment behaves differently based on the axis:

  • Y axis: The labels are aligned within the area on the left of the axis
  • X axis: The first X-axis label is aligned relative to the Y-axis

On the X axis, this parameter only affects the first label.
