Experimental Data for: Comparing Trace Visualizations for Program Comprehension through Controlled Experiments

Empirical studies, such as controlled experiments, are required to assess the effectiveness and efficiency of proposed visualization techniques. We present controlled experiments to compare the trace visualization tools EXTRAVIS and ExplorViz in typical program comprehension tasks.

We replicate the first controlled experiment with a second one targeting a differently sized software system. In addition to a thorough analysis of the strategies chosen by the participants, we report on common challenges comparing trace visualization techniques. Besides our own replication of the first experiment, we provide a package containing all our experimental data to facilitate the verifiability, reproducibility and further extensibility of our presented results.
