Struct PositionFill 

pub struct PositionFill {
    pub vjust: f64,
}

Normalized stacking to 100% (ggplot2’s position_fill(vjust = )) — like PositionStack but scaled to [0, 1] per x group.

vjust places the row’s y within its stacked segment, same as PositionStack: 1 (the default) is the segment’s top, byte- identical to before B3-4 (no ymax column). Anything else writes y = (1 − vjust)·ymin + vjust·ymax plus the ymax column.

Fields

vjust: f64

Implementations

impl PositionFill

pub fn with_vjust(self, vjust: f64) -> Self

Place y within each stacked segment (0 = bottom, 0.5 = middle, 1 = top, the default).

Trait Implementations

impl Clone for PositionFill

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PositionFill

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

Formats the value using the given formatter.

impl Default for PositionFill

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for PositionFill

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Position for PositionFill

fn compute(&self, data: &mut DataFrame, _params: &PositionParams)

Adjust positions for data.

fn name(&self) -> &str

fn per_panel(&self) -> bool

Whether this position must run separately per facet panel rather than once on the pooled rows before facets are split (B3-3, D8). Default false. PositionStack/PositionFill override this to true — a shared x category’s stack height must not mix rows from different panels. Dodge and jitter stay pooled across panels for now (a follow-up, sipemu/ggplot-rs#154).

fn validate(&self, warnings: &mut Vec<String>)

Validate this position’s own parameters once per layer (D2); default no-op. Implementations push a warning and fall back to a sane default rather than panicking or silently miscomputing.
