Existing visual analytic systems have deficiency in supporting the iterative process of analytic reasoning, which bring heavy memory burden to users. To solve these problems, this paper studies and designs a visual analytic system based on interaction history on-line tracking mechanism. Firstly this paper analyses the interactive task model, secondly studies the interaction history on-line tracking mechanism of the system. Thirdly the paper studies the action predicting method based on interaction history, and then put forward the visual metaphor self-adapting layout mechanism. Finally, it gives the application instance of the system and the experiment evaluation. The result of the evaluation experiment demonstrates that the system can provide natural and effective support for the process of analytic reasoning.
