An Improved Radviz Data Visualization Method
Hu Jia · 2015
Aiming to solve the problem of the present Radviz visualization algorithm of attribute value being uniformly distributed on the circumference of a circle between properties that resulted in the value offsetting of each other,which may lead to a larger data hiding,and the problem of the visual graphics being retracted,we propose a new visualization algorithm.By using only aquarter of a circle,the new algorithm enhances the force between the attributes,reduces the data cover degree,and better maintains the characteristics of the original data set.Through two groups of experiments to verify this new improved algorithm of Radviz,the experimental result shows that the modified algorithm visualization effect is better than that of the original Radviz.In order for the spring model to continue to be used in the new algorithm,we put forward the concept of fixed point elasticity coefficient and propose two formulae to determine the elastic coefficient.
