Show nodes as points

This geom is equivalent in functionality to geom_point and allows for simple plotting of nodes in different shapes, colours and sizes.

geom_node_point(mapping = NULL, data = NULL, position = "identity",
  show.legend = NA, ...)

Set of aesthetic mappings created by aes or aes_. By default x and y are mapped to x and y in the node data.


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.


Position adjustment, either as a string, or the result of a call to a position adjustment function.


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.


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.


geom_node_point understand the following aesthetics. Bold aesthetics are automatically set, but can be overridden.

  • x

  • y

  • alpha

  • colour

  • fill

  • shape

  • size

  • stroke

  • filter
