Waffle (Square pie chart) Geom — geom

There are two special/critical aes() mappings:

fill (so the geom knows which column to map the fills to)
values (which column you're mapping the filling for the squares with)

geom_waffle(mapping = NULL, data = NULL, n_rows = 10,
  make_proportional = FALSE, flip = FALSE, na.rm = NA,
  show.legend = NA, radius = grid::unit(0, "npc"),
  inherit.aes = TRUE, ...)

stat_waffle(mapping = NULL, data = NULL, geom = "waffle",
  n_rows = 10, make_proportional = FALSE, flip = FALSE,
  radius = grid::unit(0, "npc"), na.rm = NA, show.legend = NA,
  inherit.aes = TRUE, ...)

Arguments

mapping	Set of aesthetic mappings created by `aes()` or `aes_()`. If specified and `inherit.aes = TRUE` (the default), it is combined with the default mapping at the top level of the plot. You must supply `mapping` if there is no plot mapping.
data	The data to be displayed in this layer. There are three options: If `NULL`, the default, the data is inherited from the plot data as specified in the call to `ggplot()`. A `data.frame`, or other object, will override the plot data. All objects will be fortified to produce a data frame. See `fortify()` for which variables will be created. A `function` will be called with a single argument, the plot data. The return value must be a `data.frame.`, and will be used as the layer data.
n_rows	how many rows should there be in the waffle chart? default is 10
make_proportional	compute proportions from the raw values? (i.e. each value `n` will be replaced with `n`/`sum(n)`); default is `FALSE`.
flip	If `TRUE`, flip x and y coords. n_rows then becomes n_cols. Useful to achieve waffle column chart effect. Defaults is `FALSE`.
na.rm	If `FALSE`, the default, missing values are removed with a warning. If `TRUE`, missing values are silently removed.
show.legend	logical. Should this layer be included in the legends? `NA`, the default, includes if any aesthetics are mapped. `FALSE` never includes, and `TRUE` always includes. It can also be a named logical vector to finely select the aesthetics to display.
radius	radius for round squares
inherit.aes	If `FALSE`, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification, e.g. `borders()`.
...	other arguments passed on to `layer()`. These are often aesthetics, used to set an aesthetic to a fixed value, like `color = "red"` or `size = 3`. They may also be parameters to the paired geom/stat.
geom	geom to use (default is "waffle")

Format

An object of class GeomWaffle (inherits from GeomRtile, GeomRrect, Geom, ggproto, gg) of length 5.

Examples

data.frame(
  parts = factor(rep(month.abb[1:3], 3), levels=month.abb[1:3]),
  vals = c(10, 20, 30, 6, 14, 40, 30, 20, 10),
  fct = c(rep("Thing 1", 3), rep("Thing 2", 3), rep("Thing 3", 3))
) -> xdf

ggplot(xdf, aes(fill = parts, values = vals)) +
  geom_waffle() +
