2D and 3D Scatter Plot Display for Tours


Display method for a high performance 2D or 3D scatter plot. Performance is achieved through the use of Three.js / WebGL, and the 2D or 3D variant is selected automatically based on the tour generator provided.

a detour object


used to support aesthetic parameters for the plot, including

  • size: point size, defaults to 1

  • alpha: point opacity, defaults to 1

  • background_colour: defaults to "white"


Colour palette to use with the colour aesthetic. Can be:

  • A character vector of R colours. This should match the number of levels of the colour aesthetic, or the number of bins to use for continuous colours.

  • A function which takes the number of colours to use as input and returns a character vector of colour names and / or hex values as output.


If TRUE, center the projected data to (0, 0, 0).


Can be one of:

  • TRUE draw axes and use column names for axis labels

  • FALSE do not draw axes or labels

  • NULL draw axes with no labels

  • An unnamed vector of labels with the same length as cols

  • A named vector in the form c("h" = "head"), where head is renamed to h


A two column numeric matrix giving indices of ends of lines.


whether the widget should be initialised in the 'paused' state


used as a multiplier for the point coordinates so they are displayed on a sensible range. Defaults to the reciprocal of maximum distance from a point to the origin.


This display method produces an interactive scatterplot animation which supports both 2D and 3D tours. Linked selection and filtering is also supported using crosstalk. The set of interactive controls available are:
