Pass in a data frame of states and values and let this do the work. It enables easy faceting and makes it simpler to have a uniform legend across all the plots.

There are two special/critical aes() mappings:

  • state (so the geom knows which column to map the state names/abbrevs to)

  • fill (which column you're mapping the filling for the squares with)

  mapping = NULL,
  data = NULL,
  border_col = "white",
  border_size = 2,
  lbl_size = 3,
  dark_lbl = "black",
  light_lbl = "white",
  radius = grid::unit(6, "pt"),
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE




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.


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.


border color of the state squares, default "white"


thickness of the square state borders


font size (relative) of the label text

dark_lbl, light_lbl

colrs to be uses when the label should be dark or light. The function automagically computes when this should be.


the corner radius


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.


If FALSE, the default, missing values are removed with a warning. If TRUE, missing values are silently removed.


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.


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().


An object of class GeomStatebins (inherits from Geom, ggproto, gg) of length 7.
