Calculate two-dimensional bins using scale breaks — stat_bin_2d

This is mostly equivalent to ggplot2::stat_bin_2d() except that the bin edges can be copied from the scale breaks. For this effect to work properly, you either need to use fixed scale breaks (e.g. using a vector instead of a function), or use the breaks_cached() helper.

Usage

stat_bin_2d_auto(
  mapping = NULL,
  data = NULL,
  geom = "tile",
  position = "identity",
  ...,
  breaks = "all",
  bins = 30,
  binwidth = NULL,
  drop = TRUE,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)

Arguments

mapping, data, geom, position, bins, binwidth, drop, na.rm, show.legend, inherit.aes, ...: See ggplot2::stat_bin_2d().
breaks: Controls the break positions for the bins. Can be NULL, a numeric vector, or a function as per ggplot2::stat_bin(). Can additionally be a character specifying which breaks from the scale should be used: "minor" for minor breaks, "major" for major breaks, or "all" for both. This can be a scalar or a list of length 2 to control the axes separately.

Value

ggplot2 stat layer.

Examples

library(ggplot2)

ggplot(diamonds, aes(x, y)) +
  scale_x_continuous(limits = c(4, 10)) +
  scale_y_continuous(limits = c(4, 10)) +
  stat_bin_2d_auto()
#> Warning: Removed 478 rows containing non-finite outside the scale range
#> (`stat_bin2d_auto()`).


# You can control the x and y binning separately:
ggplot(diamonds, aes(x, y)) +
  scale_x_continuous(limits = c(4, 10)) +
  scale_y_continuous(limits = c(4, 10)) +
  stat_bin_2d_auto(breaks = list("major", NULL), bins = list(NULL, 20))
