stat-waffle
Waffle statistic: turn per-group counts into unit grid cells.
Counts one cell per row, or the rounded sum of the weight aesthetic when mapped (the pre-aggregated (category, count) case). Cells fill the grid column-major from the bottom-left: rows cells stack up a column, then the next column starts. Groups (usually the fill aesthetic) occupy consecutive runs in first-appearance order, so the grid reads as a whole made of parts. The stat emits integer x/y centres for geom-tile; no input x/y mapping is needed.
Usage
stat-waffle(
rows: 10,
)Parameters
| Parameter | Default | Description |
|---|---|---|

Grid height in cells (a positive integer). Columns grow as needed to hold the total count. |
Returns
Statistic object with name: "waffle", consumed by geom layers (usually @geom-tileGitHub).
Outputs
x.y.
