Xiaoyue Cheng, Dianne Cook, Heike Hofmann

TL;DR
This paper introduces a taxonomy of interactive visualization techniques for multivariate time series and longitudinal data, implemented in the R package cranvas, to enhance exploration and analysis of temporal components.
Contribution
It provides a comprehensive taxonomy and data pipeline for interactive exploration of temporal data, including implementation in an R package, bridging visualization and data analysis.
Findings
Developed a taxonomy of interactions for temporal data visualization.
Implemented interactive graphics in the R package cranvas.
Enabled linking of temporal plots with other data displays.
Abstract
Temporal data is information measured in the context of time. This contextual structure provides components that need to be explored to understand the data and that can form the basis of interactions applied to the plots. In multivariate time series we expect to see temporal dependence, long term and seasonal trends and cross-correlations. In longitudinal data we also expect within and between subject dependence. Time series and longitudinal data, although analyzed differently, are often plotted using similar displays. We provide a taxonomy of interactions on plots that can enable exploring temporal components of these data types, and describe how to build these interactions using data transformations. Because temporal data is often accompanied other types of data we also describe how to link the temporal plots with other displays of data. The ideas are conceptualized into a data…
