Enhancing Pixel Oriented Visualization by Merging Circle View and Circle Segment Visualization Techniques

摘要

Analyzing large datasets is a difficult task in data analysis. For this many techniques have been proposed to display data in such a way that analysis can be done easily. There are many techniques used for data visualization, like geometric, icon based, hierarchical, graph based (line graph) and pixel oriented visualization techniques. In pixel oriented technique a single pixel is represented by a single data value and pixel color depends on the scale of data value i.e. if its scale is high then pixel is represented with light color and if the scale is low then it is represented with dark color. Visualizing large amount of data onto the screen is a challenge, because large data sets cannot be displayed on single screen at a time. There are two different types of pixel oriented techniques, query dependent and query independent pixel oriented techniques. Query dependent pixel oriented visualization technique are circle segment visualization technique, spiral and generalize spiral technique. A hierarchical technique: circle view technique is like a pie chart. For better visualization new technique is proposed by combining the idea of circle segment and circle view technique. This will enhance visualization technique and will display the data in circle form. The circle will be divided into segments and sub segments. This technique will display time series data in pixel oriented visualization for better analysis.
