Enum LegendPosition 

pub enum LegendPosition {
    Right,
    Left,
    Top,
    Bottom,
}

Position of the legend relative to the pie chart.

Controls where the legend appears in relation to the pie chart visualization. The legend can be positioned on any of the four sides: right (default), left, top, or bottom.

Examples

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

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

// Position legend on the left side
let chart = PieChart::new(slices)
    .legend_position(LegendPosition::Left);

Layout Impact

The legend position affects how space is allocated:

• Right/Left: Legend takes a portion of horizontal space
• Top/Bottom: Legend takes a portion of vertical space

The chart automatically adjusts its size to accommodate the legend.

Variants

Right

Legend on the right side (default)

The legend appears to the right of the pie chart. This is the default position and works well for most use cases.

Left

Legend on the left side

The legend appears to the left of the pie chart. Useful when you want the chart to be more prominent on the right side of the display.

Top

Legend at the top

The legend appears above the pie chart. Best used with horizontal layout for a more compact display.

Bottom

Legend at the bottom

The legend appears below the pie chart. Works well with horizontal layout when vertical space is limited.

Trait Implementations

impl Clone for LegendPosition

fn clone(&self) -> LegendPosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LegendPosition

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

Formats the value using the given formatter.

impl Default for LegendPosition

fn default() -> LegendPosition

Returns the “default value” for a type.

impl PartialEq for LegendPosition

fn eq(&self, other: &LegendPosition) -> 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.
