Enum BarWidth 

pub enum BarWidth {
    Fixed(u32),
    Percentage(f32),
    Auto,
}

Bar width configuration options.

Determines how the width of bars is calculated based on the available chart space and the number of data points.

Examples

use embedded_charts::prelude::*;

// Fixed width bars
let fixed = BarWidth::Fixed(20); // 20 pixels wide

// Percentage width (80% of available space per bar)
let percentage = BarWidth::Percentage(0.8);

// Automatic width calculation
let auto = BarWidth::Auto;

Variants

Fixed(u32)

Fixed width in pixels.

Each bar will have exactly the specified width regardless of the available space or number of data points. This provides consistent bar appearance but may cause bars to overlap or leave unused space.

Examples

use embedded_charts::prelude::*;

let width = BarWidth::Fixed(25); // 25 pixels wide

Percentage(f32)

Percentage of available space per bar (0.0 to 1.0).

Each bar will occupy the specified percentage of the space allocated to it. For example, 0.8 means each bar uses 80% of its allocated space, leaving 20% for spacing.

Examples

use embedded_charts::prelude::*;

let width = BarWidth::Percentage(0.7); // 70% of allocated space

Auto

Automatic width calculation based on available space and data count.

The chart automatically calculates optimal bar width based on the viewport size, number of data points, and spacing requirements. This provides the best balance between bar visibility and spacing.

Examples

use embedded_charts::prelude::*;

let width = BarWidth::Auto; // Automatic calculation

Trait Implementations

impl Clone for BarWidth

fn clone(&self) -> BarWidth

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BarWidth

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

Formats the value using the given formatter.

impl PartialEq for BarWidth

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