Annotation: Custom grob

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.

Note

annotation_custom expects the grob to fill the entire viewport defined by xmin, xmax, ymin, ymax. Grobs with a different (absolute) size will be center-justified in that region. Inf values can be used to fill the full plot panel (see examples).
