Spiral displays have been developed to visualize the cyclic character of a data set. They are particularly useful for spotting seasonal patterns in time series data. This; however; requires expressive visual 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 twotone spiral display with efficient interaction facilities. These allow for easy exploration of the data space and easy adjustment of a variety of visualization parameters. Our tool is fully implemented and freely available for experimentation.
