Struct LogicalRange 

pub struct LogicalRange {
    pub left: f32,
    pub right: f32,
}

A floating-point range of bar indices on the horizontal axis.

left and right may extend beyond [0, bar_count) when the chart is scrolled past the data edges. Use to_strict_range to clamp to valid array indices.

Fields

left: f32

Leftmost visible bar index (may be negative when scrolled past the start).

right: f32

Rightmost visible bar index (may exceed bar_count when scrolled into the future).

Implementations

impl LogicalRange

pub fn new(left: f32, right: f32) -> Self

pub fn to_strict_range(&self) -> (usize, usize)

Convert to an end-exclusive integer range, including partially visible edge slots.

pub fn length(&self) -> f32

Length of this range
