Struct MatrixRef 

pub struct MatrixRef {
    pub columns: Vec<ColumnId>,
    pub orientation: MatrixOrientation,
    pub grid_layout: GridLayout,
}

A 2-D grid declared as a bundle of column ids — and nothing more.

There is no separate matrix container, no renderer-side registry, and no new data trait. The grid is those columns in the pool; this says which ones and how to read them. Keeping the declaration inline in the render type is what lets Config + series fully define the picture: an id pointing at something the renderer holds privately would not.

z statistics come from the constituent columns’ own cached min / max / min_positive, combined. No GPU round trip, no second extent engine.

Fields

columns: Vec<ColumnId>

The grid’s constituent columns, in grid order.

orientation: MatrixOrientation

Whether each constituent column is a slice along x or along y.

grid_layout: GridLayout

Whether the coordinate columns hold cell boundaries (n + 1 values) or cell centres (n). Never inferred from the lengths.

Implementations

impl MatrixRef

pub fn effective_extent( &self, x_len: usize, y_len: usize, shortest_column_len: usize, ) -> (usize, usize)

Cells along each axis, given the coordinate column lengths.

Returns (cols, rows) in constituent-column order: cols is how many constituent columns are usable, rows how deep into each of them to read. A declaration that does not line up with the data is not an error — the smallest common extent is drawn and the caller reports the truncation. Refusing to draw would turn a data-shape surprise into a blank chart.

pub fn coordinate_cells(&self, x_len: usize, y_len: usize) -> (usize, usize)

Cells the coordinate columns alone can bound, in constituent-column order: (along, across).

The half of Self::effective_extent that does not depend on the data, split out because a caller reporting truncation has to know what the coordinates offered before the grid columns capped it.
