Research on Methods to Improve Parallel Coordinates Visualization

Article Preview

Abstract:

In parallel coordinate plots, the density could not be represented where the polylines were over intensive. Based on the problem, the aggregation degree conception was proposed. The three-dimension parallel coordinate system with the aggregation degree axis was built, and the mapping from aggregation degree to gray degree value was built. The three-dimension polylines with gray color were projected onto the original two-dimension plane, and the two-dimension parallel coordinate plots with the aggregation degree information were acquired. The results show that they are effective in representing the density change of polylines on parallel coordinate plots.
