Collection Node

Collections are similar to histograms except that collections show the distribution of values for one numeric field relative to the values of another, rather than the occurrence of values for a single field. A collection is useful for illustrating a variable or field whose values change over time. Using 3-D graphing, you can also include a symbolic axis displaying distributions by category. Two dimensional Collections are shown as stacked bar charts, with overlays where used. See the topic Aesthetics, Overlays, Panels, and Animation for more information.
