Abstract Matrices are data structures that underlies many types of visualizations, such as heatmaps. Lots of algorithms permute their rows and columns in order to improve visual understanding and highlight patterns. Previous works used Matrix Reordering Analyzer (MRA) tool for helping to create new reordering algorithms (MB and SMB, based on multiple binarization of matrices) and specially for comparing reordering quality and execution time of algorithms. Analysis of these algorithms pointed out good results for reordering matrices whose data obey some canonical data pattern defined by the literature. However, algorithms SMB and MB were tested only with canonical patterns configured with fixed parameters. Therefore, this research project aims to increase the analysis of applying algorithms SMB and MB for reordering matrices created from canonical data patterns, taking into consideration possible variations of these patterns. Besides, this work also aims to adapt MRA for automatic creation of graphics about reordering experiments, which currently is made through spreadsheet editors. | |
