Graphical user interface component to transpose a histogram
A histogram of values recorded during time units in a time period is represented by dividing the time period into a set of time segments, each time segment thereby being associated with a subset of histogram bins. A graph is displayed that includes drawing an expanding spiral according to a golden ratio spiral, and defining a set of quarter circles using the expanding spiral, each quarter circle having an edge formed by a portion of the expanding spiral, and a center. Drawn within a quarter circle is a set of sectors about the center of the quarter circle. The quarter circle represents a time segment and the set of sectors represent time units.
