Abstract: Software Ⅰ-Miner is lack of visualization methods of association rules, and existed visualization methods of association rules have many shortcomings, such as ambiguity, shelter, disorder and so on. The paper presented two visualization methods, named improved parallel methods and improved U-matrix methods, which solved the ambiguity and shelter problem by using the combination of color, words, and lines; and avoided the disorder problem using page display of the rules. The two methods made up for the lack of visualization methods of association rules in software Ⅰ-Miner.
