Figure 1: Enhanced interactive spiral display – Left to right: Red sequential color scale, rainbow color scale, and custom color scale Spiral displays have been developed to visualize the cyclic charac-ter of a data set. They are particularly useful for spotting seasonal patterns in time series data. This, however, requires expressive vi-sual encoding and efficient interaction. In this paper, we improve existing spiral displays by applying the expressive two-tone pseudo coloring. This allows users to read off data values more precisely. More importantly, we enhance our two-tone spiral display with efficient interaction facilities. These allow for easy exploration of the data space and easy adjustment of a vari-ety of visualization parameters. Our tool is fully implemented and freely available for experimentation.
