Résumé
Software are getting more and more complex and are developed by teams that are constantly changing and not necessarily working in the same location. Moreover, most software, nowadays, are recycled rather than being developed from scratch. A comprehension task is crucial when performing maintenance tasks; it consists of analyzing multiple software dimensions concurrently. Time is one of these dimensions, as software change state with time in two manners: during their execution and during their evolution. These changes make sense only when analyzed within the context of other software dimensions, such as structure or bug information. Multidimensional analysis is a difficult problem to solve. However, there are certain methods that bypass this difficulty, such as semiautomatic approaches. Software visualization is one of them, as it allows being part of the analysis by exploring and guiding information search.
