ggplot2 (version 2.0.0)

annotation_custom: Annotation: Custom grob.

Description

This is a special geom intended for use as static annotations that are the same in every panel. These annotations will not affect scales (i.e. the x and y axes will not grow to cover the range of the grob, and the grob will not be modified by any ggplot settings or mappings).

Usage

annotation_custom(grob, xmin = -Inf, xmax = Inf, ymin = -Inf,
  ymax = Inf)

Arguments

grob

grob to display

xmin, xmax

x location (in data coordinates) giving horizontal location of raster

ymin, ymax

y location (in data coordinates) giving vertical location of raster

Details

Most useful for adding tables, inset plots, and other grid-based decorations.

Examples

# Dummy plot
df <- data.frame(x = 1:10, y = 1:10)
base <- ggplot(df, aes(x, y)) +
  geom_blank() +
  theme_bw()
# Adding a table
if (require(gridExtra)) {
base + annotation_custom(grob = tableGrob(head(iris[ ,1:3])),
        xmin = 3, xmax = 6, ymin = 2, ymax = 8)
# full panel
base + annotation_custom(grob = roundrectGrob(),
          xmin = -Inf, xmax = Inf, ymin = -Inf, ymax = Inf)
}
# Inset plot
df2 <- data.frame(x = 1 , y = 1)
g <- ggplotGrob(ggplot(df2, aes(x, y)) +
  geom_point() +
  theme(plot.background = element_rect(colour = "black")))
base +
  annotation_custom(grob = g, xmin = 1, xmax = 10, ymin = 8, ymax = 10)
