Pixel-oriented Visualization Techniques for Exploring Very Large Databases
An important goal of visualization technology is to support the exploration and analysis of very large amounts of data. In this paper, we describe a set of pixeloriented visualization techniques which use each pixel of the display to visualize one data value and therefore allow the visualization of the largest amount of data possible. Most of the techniques have been specifically designed for v...
متن کاملTechniques for Large Data Visualization
Often scientific datasets are several times larger than the main memory of a computer. The size of datasets, in general, has exceeded that of main memory for several decades and will continue to do so for the foreseeable future. Because of large disk-drive latency, visualization algorithms designed to process data from main memory can rarely be directly applied to data stored on disk without mo...
متن کاملPixel bar charts: a visualization technique for very large multi-attributes data sets{
{Portions reprinted, with permission from Keim et al. #2001 IEEE Abstract Simple presentation graphics are intuitive and easy-to-use, but show only highly aggregated data presenting only a very small number of data values (as in the case of bar charts) and may have a high degree of overlap occluding a significant portion of the data values (as in the case of the x-y plots). In this article, we ...

متن کاملDesigning Pixel-Oriented Visualization Techniques: Theory and Applications
ÐVisualization techniques are of increasing importance in exploring and analyzing large amounts of multidimensional information. One important class of visualization techniques which is particularly interesting for visualizing very large multidimensional data sets is the class of pixel-oriented techniques. The basic idea of pixel-oriented visualization techniques is to represent as many data ob...
