UpSet plots are a method for visualizing set data with more than three intersecting sets. UpSet shows intersections in a matrix, with the rows of the matrix corresponding to the sets, and the columns to the intersections between these sets (or vice versa). The size of the sets and of the intersections are shown as bar charts.

History

UpSet plots were first proposed in 2014 [1]. The first prototype was implemented as an interactive, web-based application[2]. UpSet plots are also related to Mosaic Plots, though Mosaic plots are designed for categorical instead of set data. UpSet plots became popular as they were re-implemented in various programming languages, such as R (based on Matplotlib)[3], Python, and others[4]. As of May 2022, UpSet R has been downloaded from C-RAN more than 1 million times[5]. UpSet plots are now frequently used instead of Venn diagrams, especially in life sciences [6].== Usage ==


An upset matrix is shown on the left, where each row corresponds to an intersection of multiple sets, which are shown in the columns. Three intersections (just in B; in A and B, but not in C; and in all of A, B, and C) are highlighted and the corresponding segments are shown in a Venn diagram.

An UpSet plot showing three sets (A, B, and C) and the corresponding Venn diagram. The size of the intersections (the cardinality) in the UpSet plot are visualized using labelled bar charts. The venn diagram labels the intersections.

UpSet plots tend to perform better than Venn diagrams for larger numbers of sets and when it is desirable to also show contextual information about the set intersections[7].
