Abstract: Restricted by Cartesian coordinate system and affected by the amount of resource，the multivariable visualization and analysis of a large number of resources become difficult points during grid resource searching.A new visualization method for resource searching based on parallel coordinate is presented to map multi-dimensional data to two-dimensional space.Three new visualization measures are given，coverage of resource，overlap of resource and similarity of resource.The assessment and optimization of visualization result and clustering quality are studied.New method overcomes the drawback of unscalability of traditional methods to handle growing amounts of resource.The visualization based on new measurements dynamically adjusts the data distribution on coordinate axis and quantificationally assesses the clustering assessment.
