An extension of geom_point into the third dimension.

Note that points in ggplot2 are circles, and this function still plots circles, but with the option of raising or lowering the circle in the z direction.

geom_point_z(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  ...,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE,
  extrude = FALSE,
  material = list(),
  npolys = 10,
  keep2d = FALSE
)

Arguments

mapping, data, stat, position, ..., na.rm, show.legend, inherit.aes	see documentation for ggplot2::geom_point()
extrude	whether or not to extrude the polygon
material	Arguments passed to rgl::material3d() to specify the material properties for this geom. Any parameters specified in this argument override the defaults. See rgl documentation for more info. Also see ggrgl::standard_material for the standard default material parameters used for all objects.
npolys	Circles in ggrgl are approximated by polygons. npolys controls how many polygons are used to represent each cicle. Default: 10
keep2d	keep the original 2d representation? default: FALSE

Details

For points with a fully 3-dimensional appearance see geom_sphere_3d.

Z Offset Geom

The z suffix indicates that this geom produces planar graphical elements, parallel to the ground i.e. the drawn element is the same as that for ggplot2 except it has a vertical offset (constant across each graphical element).

Geom Supports Extrusion

This geometry supports extrusion. Set extrude = TRUE and adjust aesthetics:

extrude_face_fill

The colour of the extruded faces. Default: 'grey20'

extrude_face_alpha

Alpha for the extruded faces. Default: 1

extrude_edge_colour

Colour of the edges of the extrusion. Default: NA (invisible)

extrude_edge_alpha

Alpha for the extruded edges. Default: 1

extrude_edge_size

Width of the line to draw the extruded edge. Default: 1

extrude_z

The lower limit of the extrudsion. Default: 0.05
