Item Congnostics: Visual Features for Doubly Time Series Plots(The Eurographics Association, 2020) Nguyen, Bao Dien Quoc; Hewett, Rattikorn; Dang, Tommy; Turkay, Cagatay and Vrotsou, KaterinaIn this paper, we propose an analytical approach to automatically extract visual features from doubly time series capturing the unusual associations which are not otherwise possible by investigating individual time series alone. We have extended the visual measures for 2D scatterplots, incorporated univariate time series analysis, and proposed new visual features for doubly time series plots. These measures are discussed and demonstrated via visual examples to clarify their implications and their effectiveness. The results show that distributions, trend, shape, noise, among other characteristics, can be used to uncover the latent features and events in temporal datasets.Item DualNetView: Dual Views for Visualizing the Dynamics of Networks(The Eurographics Association, 2020) Pham, Vung; Nguyen, V. T. Ngan; Dang, Tommy; Turkay, Cagatay and Vrotsou, KaterinaThe force-directed layout is a popular visual method for revealing network structures, such as clusters and important vertices. However, it is not capable of representing temporal patterns, such as how clusters/communities evolve. Dynamic network visualizations trade the overall structures for temporal relationships. In this paper, we present a dual view framework for capturing both overall structures and temporal patterns within networks. The linked supplemental views utilize the strengths of both visualization techniques to provide useful insights into the given networks. To demonstrate the usefulness of our proposed dual views, we provide three use cases of dynamic networks: computer networks communications, activities of suspicious processes in computer systems, and social networks.
