Figure \ref{fig:saxdiscordsankey} visualizes the frequency of the SAX strings and substrings in the form of an augmented suffix tree. Suffix trees have been an integral part of string manipulation and mining for decades \citep{Weiner:1973gq}. Augmented suffix trees enable a means of visualizing the substring patterns to show frequency at each level. This figure incorporates the use of a sankey diagram to visualize the tree with each substring bar height representing the number of substring patterns existing through each window of the day-types. The more frequent patterns are categorized as motifs, or patterns which best describe the average behavior of the system. One can see the patterns with the lower frequencies and their indication as discords, or subsequences that are least common in the stream.
