Enum GridSpacing 

pub enum GridSpacing {
    Auto {
        target_count: usize,
    },
    Fixed {
        interval: f64,
    },
    Custom {
        values: Vec<f64>,
    },
    LogDecades {
        subdivisions: usize,
    },
    TimeAware,
}

Grid spacing strategy.

Determines how grid lines are positioned.

Variants

Auto

Automatic spacing targeting a specific number of lines.

Fields

target_count: usize

Target number of major grid lines.

Fixed

Fixed interval between grid lines.

Fields

interval: f64

Interval in data units.

Custom

Custom grid line positions.

Fields

values: Vec<f64>

Explicit data values where grid lines should appear.

LogDecades

Logarithmic decades (for log scales).

Fields

subdivisions: usize

Number of subdivisions per decade (1, 2, 5, or 10 are common).

TimeAware

Time-aware spacing (smart intervals for time data).

Automatically chooses intervals like seconds, minutes, hours, etc.

Implementations

impl GridSpacing

pub fn auto(count: usize) -> Self

Create auto spacing with the given target count.

pub fn fixed(interval: f64) -> Self

Create fixed spacing with the given interval.

pub fn custom(values: Vec<f64>) -> Self

Create custom spacing with explicit values.

pub fn log_decades(subdivisions: usize) -> Self

Create log decade spacing.

pub fn calculate_positions( &self, min: f64, max: f64, minor_divisions: usize, ) -> (Vec<f64>, Vec<f64>)

Calculate grid line positions for the given range.

Returns (major_positions, minor_positions).

Trait Implementations

impl Clone for GridSpacing

fn clone(&self) -> GridSpacing

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GridSpacing

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

Formats the value using the given formatter.

impl Default for GridSpacing

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for GridSpacing

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