abstract: >-
  Runtime data of software systems is often of multivariate
  nature, describing different aspects of performance among
  other characteristics, and evolves along different
  versions or changes depending on the execution context.
  This poses a challenge for visualizations, which are
  typically only two- or three-dimensional. Using
  dimensionality reduction, we project the multivariate
  runtime data to 2D and visualize the result in a scatter
  plot. To show changes over time, we apply the projection
  to multiple timestamps and connect temporally adjacent
  points to form trajectories. This allows for cluster and
  outlier detection, analysis of co-evolution, and finding
  temporal patterns. While projected temporal trajectories
  have been applied to other domains before, we use it to
  visualize software evolution and execution context changes
  as evolution paths. We experiment with and report results
  of two application examples: (I) the runtime evolution
  along different versions of components from the Apache
  Commons project, and (II) a benchmark suite from
  scientific visualization comparing different rendering
  techniques along camera paths.
