Enum LegendLayout 

pub enum LegendLayout {
    Vertical,
    Horizontal,
}

Layout mode for the legend.

Controls how legend items are arranged: either stacked vertically in a column (default) or arranged horizontally in a single row.

Examples

use tui_piechart::{PieChart, PieSlice, LegendLayout, LegendPosition};
use ratatui::style::Color;

let slices = vec![
    PieSlice::new("Rust", 45.0, Color::Red),
    PieSlice::new("Go", 30.0, Color::Blue),
];

// Use horizontal layout with legend at top
let chart = PieChart::new(slices)
    .legend_position(LegendPosition::Top)
    .legend_layout(LegendLayout::Horizontal);

Layout Considerations

• Vertical: Each legend item takes one line. Best for detailed legends with longer labels or when vertical space is available.
• Horizontal: All legend items on one line. Best for compact displays or when used with Top/Bottom positions.

Variants

Vertical

Vertical layout - items stacked vertically (default)

Each legend item appears on its own line, stacked vertically:

● Item 1  45%
● Item 2  30%
● Item 3  25%

This is the default layout and provides clear separation between items.

Horizontal

Horizontal layout - items in a single row

All legend items appear in a single horizontal row:

● Item 1  45%  ● Item 2  30%  ● Item 3  25%

This layout is more compact and works well with Top/Bottom positions. The chart automatically calculates required width to prevent item cutoff.

Trait Implementations

impl Clone for LegendLayout

fn clone(&self) -> LegendLayout

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LegendLayout

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LegendLayout

fn default() -> LegendLayout

Returns the “default value” for a type.

impl PartialEq for LegendLayout

fn eq(&self, other: &LegendLayout) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
