Hexagonal binning is a technique used to show the density of a large number of points. We can encode the density of the data in two ways. The first of which is by colour, this means that more dense areas of the plot are encoded with darker hexagons. The second is where we set the area of each hexagon to correspond to the density within its locality. This means that more dense regions have larger hexagons.
This example is a simple one which enables transitions between the two encodings.
The following video demonstrates the
hexbin example found in the
sjpMScThesis package, which can be downloaded at my Master’s Thesis page.
To run this example yourself, open R and run the following
library(sjpMScThesis) ; thesisExample("hexbin")
