Abstract
In this paper, we prototype a visualization system of characters’ activity for considering user’s intention for analysis of match in the "League of Legends" (LoL). Previous system calculates characters’ activity based on three attributes with constant weights and per minute time period during the match. Therefore, a user can not reflect his/her intention to analysis by controlling weights of attributes and select time period during the match. In this paper, we extend the previous system and allow user controlling weight of the attributes and select time period during the match.
