Struct StepStrategy 

pub struct StepStrategy {
    last_point: Option<Pos2>,
}

Step-style rendering: horizontal segments with vertical transitions.

Fields

last_point: Option<Pos2>

Trait Implementations

impl Default for StepStrategy

fn default() -> StepStrategy

Returns the “default value” for a type.

impl RenderStrategy for StepStrategy

fn reset_state(&mut self)

Reset state after encountering undefined values.

fn last_point(&self) -> Option<Pos2>

Get the last rendered point (for Range connection).

fn set_last_point(&mut self, point: Pos2)

Set the last rendered point (after Range draws).

fn render_flat( &mut self, ctx: &mut DrawingContext<'_>, render_ctx: &RenderContext, start_px: f32, start_val: f64, end_px: f32, _end_val: f64, )

Render a flat segment. Step: horizontal line at start_val, connect to next. Interpolated: line from (start_px, start_val) to (end_px, end_val).

fn render_range( &mut self, ctx: &mut DrawingContext<'_>, render_ctx: &RenderContext, px: f32, min_val: f64, max_val: f64, )

Render a range segment (default impl, same for both strategies). Draws vertical bar at px from min_val to max_val.
